OX Tools Cartridge Applicators (Caulking Guns)
An OX caulking gun is the bit of kit you reach for when sealant needs going in clean, controlled, and without fighting the trigger all day.
For sealing baths, bedding frames, filling movement joints or running silicone round second fix, a decent gun saves waste and gives you a neater bead first time. The OX applicator guns range covers solid site-ready options that suit regular cartridge work without feeling flimsy after a week in the van.
What Are OX Caulking Guns Used For?
- Sealing around baths, showers, sinks and worktops, where a steady feed and proper trigger control help you lay silicone neatly without leaving a mess to tidy after.
- Applying frame sealant around windows, doors and internal joinery, which matters on snagging jobs where gaps show up fast and the finish needs to look right first time.
- Running adhesive from standard cartridges onto boards, trims and panels, especially when you need more control than squeezing by hand and do not want product wasted down the side.
- Filling movement joints and perimeter gaps on fit-out and refurb work, where an OX cartridge applicator gives you better pressure and a more even bead over longer runs.
- Handling day-to-day mastic and sealant work in vans, workshops and site boxes, where robust frames and simple loading matter more than fancy extras that do not earn their keep.
Choosing the Right OX Caulking Gun
Sorting the right one is simple: match the frame and feed to the sealant you use most, not just the cheapest gun on the page.
1. Skeleton or Cradle
If you are mainly running standard silicone or decorators caulk from regular cartridges, an OX skeleton caulking gun is lighter and easier to carry round all day. If cartridges get knocked about in the van or you are using stiffer materials, a cradle style gives the tube more support and usually feels steadier on long beads.
2. Trigger Feel Matters More Than You Think
If you only use a gun now and then, a basic manual model will do the job. If you are sealing kitchens, bathrooms or frames every week, buy the one with smoother action and better push ratio because your hand will know the difference by lunchtime.
3. Check Cartridge Size First
Do not assume every gun takes every tube. Most day-to-day work is standard cartridges, but if you are set on an OX 400ml applicator gun, make sure the sealant or adhesive you use matches the gun capacity before you order.
4. Buy for the Material, Not Just the Bead
If you are pushing soft sanitary silicone, almost any decent gun will manage. If you are using thicker grab adhesives or heavy mastic, go for a sturdier OX cartridge applicator with enough leverage, otherwise you will fight the trigger and end up with an uneven finish.
Who Uses These on Site?
- Bathroom fitters rely on an OX silicone gun for sealing trays, baths and basins cleanly, especially when the final bead is the bit the customer stares at first.
- Window and door installers use an OX mastic gun for perimeter sealing round frames, where smooth trigger pressure helps keep lines tidy and cuts back on wipe-off.
- Kitchen fitters keep one in the van for worktops, upstands and trim fixing, because cartridge adhesive and sealant jobs crop up on nearly every install.
- Decorators and maintenance teams use them for filling cracks, sealing edges and sorting snagging, where quick loading and reliable feed save time over a full day of small jobs.
- General builders and chippies reach for an OX 400ml applicator gun on first fix and second fix work, especially when they want site gear that does not twist or flex under pressure.
Useful Extras for OX Caulking Guns
A few cheap add-ons make sealant work cleaner, quicker and less frustrating on site.
1. Sealant Smoothing Tools
If you want neat corners and clean sanitary lines, get a proper smoothing tool. It saves you dragging sealant everywhere with a wet finger and cuts down the snagging afterwards.
2. Masking and Jointing Tapes
Clean tape lines save a lot of wipe-down, especially around finished trims, tiles and painted edges. The OX tapes range is worth keeping nearby when the finish actually matters.
3. Spare Cartridges and Sealants
Nothing wastes time like running out halfway round a bath or frame. Keeping the right tubes from the OX sealants and adhesives range means you can finish the run in one go without patching sections later.
Choose the Right OX Caulking Gun for the Job
Use this quick guide to sort the right gun for the type of sealing work you do most.
| Your Job | Category or Type | Key Features |
|---|---|---|
| Occasional sealing round baths, sinks and skirtings | Skeleton caulking gun | Light to carry, simple to load, fine for standard silicone and caulk cartridges |
| Regular window and door perimeter sealing | Cradle caulking gun | Better cartridge support, steadier feed, more control on longer runs |
| Applying thicker grab adhesives and heavy sealants | Higher leverage cartridge applicator | Smoother trigger pressure, less hand strain, better with stiff materials |
| General van stock for snagging and maintenance jobs | Standard OX cartridge applicator | Takes common cartridge sizes, quick for small repairs, easy to keep in the tool bag |
| Larger volume work with 400ml cartridges | OX 400ml applicator gun | Sized for bigger tubes, fewer changeovers, better for longer uninterrupted beads |
Common Buying and Usage Mistakes
- Buying on price alone and ending up with a gun that flexes under pressure. That usually means jerky feed, sore hands and a rough bead, so pick one that suits how often you actually use it.
- Not checking cartridge size before ordering. If the tube does not match the gun, you are stuck on site with the wrong kit and a job that cannot be finished properly.
- Using a light skeleton gun for thick adhesive all day. It will do in a pinch, but for heavy product you want more leverage or you will fight it from the first squeeze.
- Cutting the nozzle too big too early. Once that bead is oversized, you will waste sealant and spend longer cleaning edges than sealing the joint.
- Leaving old product in the frame and rod after use. Dried sealant gums everything up, so wipe it down before it sets and the next cartridge will load properly.
Skeleton Caulking Guns vs Cradle Guns vs High Leverage Guns
Skeleton Caulking Guns
These are the straightforward choice for general silicone and decorators caulk. They are lighter, cheaper and easy to keep in the van, but they offer less support for the cartridge and can feel harder work with thick materials.
Cradle Caulking Guns
Cradle guns hold the cartridge more securely, which helps on longer runs round frames, baths and boards. If your tubes get battered in transit or you want a steadier feel, this is often the better everyday site option.
High Leverage Guns
If you use dense adhesive or tougher sealants, high leverage guns make the job easier on your hand and give better flow control. They are worth it for regular use, but they are more gun than you need for the odd small bead of sanitary silicone.
Maintenance and Care
Clean It After Each Cartridge
Wipe the frame, plunger and trigger area before sealant skins over. It takes a minute and stops the rod sticking or dragging next time you load up.
Store It Dry in the Van or Box
Do not leave it rolling around wet behind the seats. Keeping your OX sealant gun dry helps prevent surface rust and stops grit getting into the trigger mechanism.
Check the Rod and Release
If the push rod is bent or the release plate is clogged, feed becomes jerky fast. Sort it early before you ruin a bead on finished work.
Do Not Force Damaged Cartridges
Split or crushed tubes can jam the gun and make a mess inside the frame. Swap the cartridge rather than trying to bully it through and wasting half the product.
Replace When the Action Turns Rough
If the trigger slips, the frame twists or the rod no longer tracks straight, it is usually time for another. For heavier regular use, look at the OX Pro cartridge applicators range.

OX 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 cleaner sealing around baths, frames, skirtings, kitchens and joints, without trying to squeeze product out by hand and making a mess of it.
What is the difference between a skeleton and cradle caulking gun?
A skeleton caulking gun has an open frame and is lighter, so it is handy for general cartridge work and quick jobs. A cradle gun supports the full cartridge body, which makes it steadier on long runs and better when tubes get knocked about or the material is a bit stiffer.
Are OX caulking guns any good?
Yes, OX caulking guns are a solid choice for trade use. They are built for site handling, the frames feel properly usable rather than flimsy, and they suit the sort of sealing and adhesive jobs that come up week in, week out on fit-outs, bathrooms and general snagging.
What size cartridge does a caulking gun take?
Most standard caulking guns take common cartridge sizes used for silicone, caulk and sealant, but not every gun takes every tube. Always check the product spec before ordering, especially if you need an OX 400ml applicator gun or are using anything outside a standard cartridge format.
How do you load a caulking gun?
Press the release, pull the rod back fully, drop the cartridge into the frame, then push the rod forward until it sits against the tube base. Cut the nozzle to size, pierce the inner seal if needed, and give the trigger a few squeezes until the product starts feeding cleanly.
Will an OX caulking gun handle thick adhesive as well as silicone?
Some will, yes, but it depends on the gun and the material. For soft sanitary silicone, most manual guns are fine. For thicker grab adhesive or heavy mastic, pick a sturdier model with better leverage, otherwise the trigger can feel hard work and the bead will be less consistent.
Do I need a separate gun for 400ml cartridges?
If the cartridge size is larger than a standard tube, usually yes. A gun sized for 400ml cartridges gives the tube proper support and correct travel, which stops awkward loading and wasted product when the plunger does not line up as it should.
