Exhaust Rain Caps
Exhaust Rain Caps
Protect your exhaust system from water ingress with our high-quality rain caps. Designed for vertical stacks and industrial or agricultural vehicles, these caps open with exhaust pressure and shut when idle — keeping out rain, dirt, and debris.
Made from durable materials with a spring-loaded hinge, our rain caps are perfect for tractors, trucks, and machinery that operate outdoors or in harsh environments. Easy to install and reliable in all conditions.
Looking to build your own vertical system? Pair rain caps with exhaust pipe & tube and clamps for a secure fit. Finish off the job with universal mufflers or custom tips for your application.
Popular in 4x4 and off-road setups, our rain caps are available in various pipe sizes and finishes — ready to ship Australia-wide.
