The Tec7 Gun is a premium quality gun made tough to handle high 
viscosity products due to it’s massive 1:18 compression ratio. With its wide, 
rounded hand grip it’s been designed for comfort and ease of use. The Tec7 
Guns automatic no-drip system with on/off function means that the user can 
decided if the automatic no-drip function is switched on or off.

We only recommend using Tec7 caulking guns or a high quality electric caulking gun with all Tec7 adhesives.
