Rain caps are used to cover the vertical open ends of your piping system. A TIO BV rain cap protects your engine and exhaust system for the corrosive influences of rain and snow. Our rain caps are all made of SS304 in a ‘silent’ execution. This SS304 material guarantees a very long lifetime, without any maintenance. TIO BV rain caps are very well balanced to open directly after the start of the engine and close whenever the engine stops. Due to this balancing, they have a very low back pressure. Our rain caps can be executed with welding strips (type RK) or with a clamp (type RKB) and can be obtained in H (heavy duty) and L (light - commercial) executions. Other materials are on request available.
