Description
There’s nothing worse than hearing water gurgling in your muffler when you go to start your tractor after a heavy rain. Water sitting in your exhaust system causes problems you can’t see right away—internal corrosion that leads to rust-through, premature muffler failure, and contamination that’ll eventually affect engine performance. This 3.25-inch rain cap is simple protection that prevents those expensive surprises.
What You’re Getting
- Perfect 3.25-inch (82mm) size fits most standard exhaust pipes on general purpose tractors and equipment
- Hinged flap design opens automatically when exhaust pressure builds, then closes securely when you shut down
- Weather-resistant construction handles temperature extremes, UV exposure, and constant moisture cycling
- Keeps rain, snow, and debris out while still allowing normal exhaust flow during operation
Built for Real Farm Work
This cap fits a wide range of general purpose tractors and equipment that spend time sitting outside between jobs. Whether you’re running utility tractors for loader work, older equipment that stays parked in the field, or backup machines that sit for weeks at a time, exposed exhaust stacks are water magnets during storms and wet weather.
Made to Last
Unlike cheap plastic caps that crack and break after a season or two, this weather cap is built to handle years of outdoor exposure. The balanced flap mechanism works reliably even with the lower exhaust pressures from smaller engines, and the corrosion-resistant construction maintains its protection properties through harsh winter storage conditions.
Installation Notes
Installation takes just minutes—simply slide it over your exhaust pipe and secure with the clamp. Measure your exhaust pipe’s outside diameter first to confirm the 3.25-inch size is right for your equipment. The cap should fit snugly but not require hammering, and make sure the flap can open freely without hitting any nearby obstacles.
