Small engines need protection too, and water finding its way into your generator, pump engine, or compact equipment can cause just as much havoc as in larger machines. This 2.5-inch rain cap is sized perfectly for those smaller exhaust stacks, providing reliable weather protection that keeps your auxiliary equipment ready to run when you need it most.
Key Features
- 2.5-inch (63.5mm) outside diameter fits small engine exhausts perfectly
- Galvanized steel construction for long-lasting rust resistance
- Hinged cap opens automatically with exhaust flow
- Gravity-close design seals tight when engine stops
- Simple clamp attachment installs in seconds
Essential Protection for Support Equipment
Every farm depends on smaller diesel engines – the generator that keeps the lights on during outages, irrigation pump engines in the fields, air compressors in the shop, or that old diesel welder on the service truck. These 2.5-inch exhaust systems are particularly vulnerable to rain because they’re often on equipment that sits idle between uses. Water accumulation in these smaller exhausts happens quickly, and starting a water-logged engine can bend rods faster than you can hit the kill switch.
Made to Last
Don’t let the smaller size fool you – this cap is built with the same heavy-duty galvanized steel as its larger cousins. The flapper mechanism works reliably despite the lower exhaust pressures these engines produce. Galvanizing provides years of weather resistance without the maintenance painted caps require.
Installation Notes
Measure your exhaust pipe’s outside diameter carefully – 63.5mm or 2.5 inches exactly. The cap should slide on firmly but not require hammering. Position the clamp where it won’t interfere with other components, and ensure the flap can open freely without hitting obstacles. These smaller caps are perfect candidates for painting bright colors – they’re easier to lose track of on cluttered equipment than larger versions.
