Clean, even joints require the right tool: the OTTO silicone cartridge guns H 17 and H 37 are reliable cartridge guns for acrylics, hybrids, polyurethanes and silicones – ideal for precise dispensing during renovation, construction and installation work. Both versions are designed for medium- to high-viscosity sealants and adhesives and support controlled, low-effort application.
The OTTO hand-operated cartridge gun H 37 is the premium solution for daily use. It is made of high-impact plastic, is particularly lightweight and features a sliding sleeve release as well as a smooth push rod for 290 / 300 / 310 ml cartridges. With a gear ratio of approx. 18:1, it is ideal when high control and comfortable force transmission are required for viscous materials.
The OTTO hand-operated cartridge gun H 17 is a solid and cost-effective option with a rotating barrel for 280 / 290 / 300 / 310 ml cartridges. The push and drive components are made of a special alloy and are corrosion-resistant. A rubberized handle and trigger improve handling. The feed mechanism is designed for increased pressure resistance and operates with a smooth push rod and ladder hook. The gear ratio is 17:1.
With the H 37, pressure release is achieved by quickly releasing or pushing forward the trigger lever. This allows fast and clean control of material flow during daily work.
Whether you choose the robust premium version or the cost-effective all-round solution: with OTTO H 17 / H 37 you get reliable cartridge guns for clean joint results and precise dispensing – perfectly suited for processing our silicone caulk.
