Description
Water sitting in your exhaust stack is trouble waiting to happen. If you’ve ever heard that sickening sound of water sloshing around in your muffler when you go to start up after a hard rain, you know exactly what I’m talking about. This galvanized rain cap keeps moisture out while still letting exhaust gases flow freely when you’re running – simple protection that prevents expensive problems down the road.
What You’re Getting
- Heavy-duty galvanized steel construction that won’t rust out like cheap painted caps
- Hinged flapper design opens automatically under exhaust pressure, closes tight when you shut down
- 2 1/4 inch (57.15mm) outside diameter fits standard general purpose tractor exhaust stacks
- Clamp-on installation that requires no drilling or welding to your existing pipe
- Weighted flap ensures positive closure without depending on springs that weaken over time
Built for Real Farm Work
This size is common on general purpose tractors, utility models, and older equipment that might not get used every day. Whether your tractor sits outside during planting season or waits under the shed between jobs, exposed exhaust stacks are magnets for rain, snow, and even curious critters looking for a warm spot.
Made to Last
The galvanized coating handles years of weather exposure without the maintenance that painted surfaces require. The hinge mechanism is built robust enough to withstand thousands of opening cycles as exhaust pressure lifts the flap during operation. When you shut down, that weighted design ensures it closes completely – no gaps for water to sneak through.
Good to Know
Installation takes about five minutes – just slide it over your exhaust pipe and secure with the included clamp. Measure your pipe’s outside diameter first to make sure you’ve got the right size. The cap should fit snugly without requiring a hammer. Check the hinge occasionally for smooth operation – a drop of oil keeps it working freely in dusty conditions.
