Sealant 310ml Gun for Vivarium & Terrarium Builds

The Sealant 310ml Gun is a standard applicator designed for use with 310ml sealant cartridges, giving reptile keepers controlled, consistent delivery when sealing vivariums and terrariums. Whether you're building a bioactive enclosure or waterproofing a background, a proper applicator gun makes the difference between a clean bead and a messy one.

Smooth, Controlled Application

The squeeze trigger mechanism allows you to regulate flow as you work, reducing waste and giving you a neater finish along seams, corners, and joins. This is particularly useful when working in the confined spaces of a vivarium where precision matters.

Compatible with 310ml Cartridges

Fits standard 310ml sealant cartridges — the format used by most reptile-grade silicones and aquarium-safe sealants. No adapters or modifications required.

A straightforward, reliable tool that takes the frustration out of sealant work, leaving you with cleaner builds and better results.
