The No Rust Raincap gives full protection to your diesel engine and is desinged to be fully automatic - opens when engine starts - closes when engine stops, prolonging the life of your diesel engine by keeping rain, sleet, snow, dust, dirt and critters out of your exhaust system.


Our exhaust covers are constructed of non-sparking cast aluminum and cast brass materials, perfect for gas pipelines and diesel engines. We also offer custom powder coating. The weathercap is maintenance free, easy to install and designed to be wind proof.

You can also add a signal flag to any size raincap for a very low cost! This addition to the Raincap is a visual indicator that alerts technicians that the pop-off relief valve has cycled. Just ask to add the signal flag when ordering!
