Description
There’s nothing worse than hearing water gurgling in your exhaust when you go to start your equipment after a good rain. Water sitting in your exhaust system causes rust, corrosion, and can even damage valves if enough accumulates. This plastic rain cap gives you simple, reliable protection that keeps moisture out while still letting exhaust gases flow freely when you’re running.
What You’re Getting
- 101.2mm inner diameter fits standard 4-inch exhaust pipes perfectly
- Durable plastic construction that won’t rust or corrode over time
- Large 250mm outer diameter provides excellent weather protection
- Direct replacement design that slides right on without modifications
Built for Real Farm Work
This cap works great on any equipment with vertical exhaust stacks – tractors, combines, generators, irrigation pumps, or backup equipment that sits idle between seasons. Whether your machine spends time parked in the field during busy seasons or stored outside year-round, this cap prevents rain from turning your exhaust into a water collector.
Made to Last
The tough plastic construction handles temperature swings, UV exposure, and constant moisture cycling without cracking or warping. Unlike metal caps that eventually rust through, this plastic design maintains its protective seal season after season, even through harsh winter storage conditions.
Installation Notes
Simply slide the cap over your exhaust pipe – it should fit snugly but not require forcing. Measure your pipe’s outside diameter first to ensure proper fit. The large outer diameter means this cap sheds water effectively while still allowing proper airflow during operation.
