Description
There’s nothing quite like the frustration of trying to start your generator or small engine after a heavy rain, only to hear that telltale water gurgling in the exhaust. Rain getting into your exhaust system causes rust, corrosion, and can even lead to bent rods if enough water accumulates. This simple weather cap keeps moisture out while still letting exhaust gases flow freely when your equipment is running.
What You’re Getting
- Precise fit for 1 to 1-3/16 inch outside diameter exhaust pipes
- Gray finish that blends with most equipment colors
- Durable construction that handles temperature swings and weather exposure
- Simple slip-on design that stays put through vibration and wind
- Automatic operation – no springs or moving parts to fail
Built for Real Farm Work
This cap is sized perfectly for the smaller exhaust stacks you’ll find on generators, pump engines, welders, air compressors, and stationary equipment around the farm. These 1-inch exhaust systems are especially vulnerable to rain damage because they’re often on equipment that sits idle between uses, giving water time to accumulate and cause problems.
Made to Last
The TISCO brand is known for making parts that hold up to farm conditions. This weather cap handles the constant temperature cycling, UV exposure, and moisture that comes with outdoor equipment storage. Unlike cheap plastic caps that crack and break, this one keeps protecting your equipment season after season.
Good to Know
Installation is as simple as sliding the cap over your exhaust pipe – it should fit snugly without needing to force it on. Measure your exhaust pipe’s outside diameter first to make sure you’re getting the right size. A quick tip from the shop: check these caps occasionally on equipment that sits for months between uses – spiders and wasps love building homes under idle rain caps.
