OX Tools Pro Cartridge Applicators (Caulking Guns)
OX Pro caulking gun range gives you controlled, clean bead application for silicone, mastic and sealant work on site, snagging jobs and fit-outs.
If you're sealing baths, bedding trims or running long beads round frames, a poor gun makes a mess and wrecks your wrists by lunchtime. The OX Pro caulking gun range is built for regular trade use, with smoother trigger action, solid frames and better control when you're laying consistent lines. If you already rate OX Pro tools, this is the same no-nonsense kit for sealing, bonding and finishing jobs properly.
What Are OX Pro Caulking Guns Used For?
- Sealing around baths, shower trays and kitchen worktops is where an OX Pro caulking gun earns its keep, giving you better control over silicone so the bead stays neat instead of ending up all over the tile.
- Running mastic and frame sealant round windows, doors and skirting boards is quicker with a solid OX Pro applicator gun, especially when you need a steady, even push across longer runs.
- Applying grab adhesive behind trims, panels and small fixings is easier when the cartridge feeds smoothly, so you are not fighting the gun every time you pull the trigger.
- Snagging and finishing work on refurbs suits an OX Pro cartridge gun well, whether you are filling movement joints, touching up cracked sealant lines or sorting the final details before handover.
- Working through multiple cartridges in one day is less of a chore with an OX Pro sealant gun that puts up with site abuse and keeps pressure consistent from the first squeeze to the last.
Choosing the Right OX Pro Caulking Gun
Sorting the right one is simple: match the gun to the material and how many cartridges you get through in a normal day.
1. Cartridge Work or Heavier Sealants
If you are mainly running standard silicone, decorators caulk or general frame sealant, a standard OX Pro cartridge gun is the obvious pick. If the material is thicker and harder to push, go for the more robust option with stronger drive and better control so you are not crushing your hand by mid-afternoon.
2. Short Snagging Jobs or All Day Use
If it only comes out now and then for touch-ups, almost any decent trade gun will do the job. If you are sealing all day on bathrooms, windows or fit-outs, buy the smoother-running OX Pro caulking gun with a solid frame, because that trigger action matters more than lads think.
3. Control Matters More Than Force
Do not just buy the stiffest gun and assume it is better. For neat visible beads, you want steady feed and clean pressure release, otherwise the sealant keeps creeping out and leaves a mess at the end of every run.
Who Uses These on Site?
- Bathroom fitters and plumbers swear by an OX Pro silicone gun for sealing trays, baths and basins cleanly, where a tidy bead saves call-backs and keeps water where it should be.
- Window and door fitters use an OX Pro mastic gun for perimeter sealing and weatherproofing, especially on longer external runs where cheap guns start flexing and jerking.
- Kitchen fitters reach for an OX Pro caulking gun when bedding upstands, sealing worktops and fixing trims, because smoother feed means less mess on finished surfaces.
- Decorators and snagging teams keep an OX Pro applicator gun in the van for quick filling and finishing work, then usually pair it with OX scrapers and filler knives for cleaning up edges and excess.
The Basics: Understanding Caulking Guns
A cartridge gun is simple kit, but getting the right type makes sealing work cleaner and faster. Here is what actually matters on site.
1. It Pushes the Cartridge, Not the Sealant
The gun drives a rod into the back of the cartridge, forcing sealant out through the nozzle. A smoother mechanism gives you a steadier bead, which is what you need for bathrooms, frames and any finish the client is going to stare at.
2. The Nozzle Cut Controls the Bead
Most of the mess on sealant jobs comes from cutting the nozzle wrong, not from the cartridge itself. Cut small if you want neat finishing work, and only open it up when you genuinely need a heavier bead for wider gaps.
3. Pressure Release Stops the Dribble
A decent OX Pro sealant gun should let pressure off cleanly when you stop squeezing. That matters because it cuts down on oozing, wasted material and the constant wiping up that slows the whole job down.
Caulking Gun Extras That Save Time on Site
The gun is only half the job. A few simple extras make sealing work cleaner and a lot less frustrating.
1. Sealants and Adhesives
Get the right cartridge for the job in the first place. There is no point pairing a decent gun with the wrong product when you are sealing wet areas, sticking trims or filling movement joints. Start with OX sealants and adhesives so the cartridge and task actually match up.
2. Scrapers and Blades
Old sealant ruins new work if you leave any behind. Keep OX scrapers and blades close by for stripping out failed silicone, cleaning back edges and tidying cured excess without chewing up the surface.
3. Spare Applicator Guns
If you swap between silicone, adhesive and mastic during the same fit-out, a second gun stops you wasting time stripping cartridges in and out. Keeping a couple of OX caulking guns in the van is a sensible move on busier jobs.
Choose the Right OX Pro Caulking Gun for the Job
Pick the gun by material thickness, finish level and how often you actually use it.
| Your Job | Caulking Gun Type | Key Features |
|---|---|---|
| Sealing baths, sinks and shower trays | Standard cartridge gun | Smooth trigger action, clean pressure control and good bead accuracy for visible silicone lines |
| Running frame sealant round doors and windows | Heavy duty cartridge gun | Stronger frame and steadier feed for longer runs and thicker mastic |
| Applying grab adhesive behind trims and panels | High thrust applicator gun | More pushing force for thicker materials that are hard work in lighter guns |
| Snagging and occasional touch-up work | General trade cartridge gun | Simple loading, reliable trigger and enough control for short bursts of use |
Common Buying and Usage Mistakes
- Buying the cheapest frame for daily work is a false economy. It twists under load, feeds badly and leaves you fighting the tool instead of laying a clean bead, so spend properly if this is regular site kit.
- Using a light-duty gun for thick adhesive or heavy mastic usually ends with sore hands and uneven application. Match the gun to the material or the whole job becomes harder than it needs to be.
- Cutting the nozzle too wide too early dumps out far more sealant than the joint needs. Start smaller, test a short run, then trim more only if the gap genuinely calls for it.
- Forgetting to release pressure after a run causes the cartridge to keep dribbling. That wastes material and makes a mess on finished surfaces, so get into the habit of stopping the flow properly.
- Leaving old cured sealant in place before resealing ruins the finish and the bond. Strip it back clean first, otherwise even a good OX Pro cartridge gun cannot rescue the result.
Open Frame vs Heavy Duty vs Drip Reduced Guns
Open Frame Guns
Best for standard silicone, decorators caulk and light snagging work. They are straightforward, quick to load and fine for general use, but they are not the first choice for thick materials or constant all-day sealing.
Heavy Duty Guns
These are the better option for thicker sealants, tougher adhesives and longer runs round frames. They put up with more abuse and keep feeding under load, though they are more gun than you need for the odd little bathroom touch-up.
Drip Reduced Guns
If neatness matters, these are worth a look because they cut down on sealant oozing after the trigger is released. That makes them handy for kitchens, bathrooms and any finished area where constant wipe-up slows you down.
Maintenance and Care
Wipe It Down After Use
Do not leave fresh sealant all over the frame and trigger. A quick clean at the end of the job stops buildup hardening round moving parts and keeps the gun feeding properly next time.
Keep the Rod Clean
The push rod needs to slide cleanly through the mechanism. If it gets clogged with dried material or site muck, the action turns jerky and you lose control of the bead.
Store It Dry in the Van or Box
Chuck it loose in the back with wet gear and you will shorten its life. Keep your OX Pro applicator gun dry and protected so the frame, spring and trigger do not corrode or get bent out of shape.
Replace Bent or Rough Running Guns
If the frame is twisted or the rod slips under pressure, stop nursing it along. Once a gun starts feeding badly, you waste more time and sealant than the replacement costs.

OX Pro Caulking Gun FAQs
What is a caulking gun used for?
A caulking gun is used to push sealant, silicone, mastic or adhesive out of a cartridge in a controlled bead. On site, that means sealing baths, frames, worktops, skirting and joints without trying to squeeze the cartridge by hand like a muppet.
What is the difference between a caulking gun and a sealant gun?
In real trade use, there usually is not much difference. Most lads use caulking gun, sealant gun, mastic gun and silicone gun to mean the same basic cartridge applicator. What matters more is whether the gun is sturdy enough for the material you are pushing through it.
Are OX Pro caulking guns any good?
Yes, for regular trade use they are a solid choice. OX Pro caulking guns are built better than throwaway DIY frames, with smoother action and better control, which matters when you are laying visible beads or getting through multiple cartridges in a day.
How do you load a cartridge gun?
Release the push rod, pull it right back, drop the cartridge into the frame, then seat the nozzle end at the front and bring the rod back onto the base of the cartridge. Cut the nozzle to size, pierce the inner seal if needed, then squeeze a little material through before starting the proper run.
What size cartridge does a caulking gun take?
Most manual caulking guns are made for standard cartridges, which covers the usual silicone, caulk and sealant tubes used on UK jobs. Always check the gun and cartridge size before buying, but standard trade cartridges are what this sort of gun is generally built around.
Will an OX Pro caulking gun cope with thick grab adhesive?
Some will, some will not comfortably, so check the duty level before you buy. For standard silicone and sealant, no issue. For thicker adhesive, you want a stronger frame and more pushing force or you will feel it in your hand straight away.
Does a better caulking gun really make a difference to the finish?
Yes, especially on visible work. A smoother gun gives you steadier feed and cleaner pressure release, which means straighter beads, less dribble and less wiping up afterwards. On bathrooms and kitchens, that absolutely shows in the final finish.
