With the TEC7 TecGun professional cartridge gun, you can dispense flexible sealants and heavy mounting adhesives with ease. Thanks to the powerful 18/1 thrust ratio, high-viscosity materials and 2-part products in standard cartridges up to 310 ml flow smoothly with minimal grip force. The built-in pressure release mechanism stops the product flow immediately, preventing unwanted dripping and ensuring neat joints. Its rotating cradle allows you to guide the nozzle effortlessly around tight corners and awkward angles. This ensures fast, precise, and fatigue-free caulking on every installation or renovation job.
