Best OverallPros
- Consistent bead with zero drip
- Works with Triton 20V battery ecosystem
- Lightweight and well balanced
Cons

- Not suitable for 600ml sausages
The Triton TSSM20 is the clear leader for anyone applying silicone sealant regularly. Its variable speed trigger allows precise control over the flow rate, which means you can lay down a perfect bead without the jerky starts common with manual guns. Owner reviews consistently praise the anti-drip mechanism that stops sealant oozing when you release the trigger.
This cordless sealant gun is part of Triton's 20V platform, so if you already own other Triton tools, you can share batteries. The tool itself is well built with a comfortable grip that reduces fatigue during long jobs. For professional plumbers and serious DIYers, this is the best Triton silicone sealant tool available.
Triton TSSM1 Manual Sealant Gun
Best Budget / DIYPros
- Very affordable
- Lightweight and easy to handle
- Smooth ratchet action
Cons
- Requires two hands for best control
- Not for heavy-duty or frequent use
The Triton TSSM1 is the perfect entry-level sealant gun for occasional DIY tasks. Its simple ratchet mechanism gives you good control over the bead, and the lightweight design means it is easy to manoeuvre in tight spaces. Owner reviews highlight the smooth action that does not stick or skip.
While it lacks the speed and convenience of a cordless model, the TSSM1 is reliable and built to last for home use. It is best suited for sealing around sinks, baths, and windows where you only need a few tubes per year. If you want a no-fuss tool that gets the job done without breaking the bank, this is the choice.
Triton TSSM2 Heavy-Duty Manual Sealant Gun
Best for Thick SealantsPros
- High thrust for thick sealants
- Durable steel construction
- Comfortable grip
Cons
- Heavier than standard manual guns
- Overkill for basic silicone
The Triton TSSM2 is built for tough jobs. Its 10:1 thrust ratio makes it easy to extrude thick, high-viscosity sealants like polyurethane and bitumen without straining your hand. The steel frame ensures it can handle repeated heavy use without flexing or breaking.
Owner reviews note that the TSSM2 feels solid and well made. It is not the best choice for everyday silicone work, but if you regularly apply construction adhesives or thick mastics, this tool will save you significant effort. It is a specialist tool for a specific need.
Triton TSSM3 Sausage Sealant Gun
Best for Large JobsPros
- Holds 600ml sausages for less waste
- Good for large areas
- Steel barrel is durable
Cons
- Not compatible with standard cartridges
- Heavy when full
The Triton TSSM3 is designed for professionals who need to apply sealant in large volumes. It accepts 600ml foil sausages, which are more economical for big jobs and produce less plastic waste than cartridges. The steel barrel and smooth ratchet mechanism ensure reliable performance.
Owner reviews mention that the TSSM3 is excellent for flooring, roofing, and large glazing projects. It is not a tool for small bathroom jobs, but if you are sealing a whole house or a commercial space, this sausage gun will save you time and money on materials.
Triton TSSM4 Caulk Finishing Kit
Best for Perfect FinishPros
- Creates professional-looking joints
- Multiple profile shapes included
- Reusable and easy to clean
Cons
- Not a sealant gun itself
- Tips can wear over time
The Triton TSSM4 is not a sealant gun but an essential accessory kit for achieving a perfect finish. It includes ten profiled smoothing tips and a handle that lets you create concave, convex, and flat joints with ease. This kit is invaluable for anyone who wants their silicone work to look neat and professional.
Owner reviews highlight that the TSSM4 eliminates the messy finger-smoothing method. The tips are made from a non-stick material that glides over the sealant without tearing it. If you already own a Triton sealant gun, adding this finishing kit will significantly improve the quality of your results.
What to check before buying a Triton silicone sealant tool
Choosing the right sealant tool depends on the scale of your work and the type of sealant you use. For occasional DIY, a manual gun like the TSSM1 is sufficient. For regular professional use, the cordless TSSM20 offers speed and consistency. Consider the battery ecosystem if you already own Triton 20V tools. Also check the thrust ratio for thick sealants and whether you need a sausage gun for large volumes.
Mistakes to avoid when using a sealant gun
A common mistake is cutting the nozzle too small or too large. Always cut at a 45-degree angle and match the hole size to the joint width. Another error is not priming the gun before use. For manual guns, squeeze a small amount onto scrap cardboard to remove air pockets. For cordless models, set the speed to low for better control. Finally, never use a manual gun for thick sealants without a high thrust ratio, as it will cause hand fatigue and poor results.
