Rainproof Exhaust Caps for Generator and Tractor Flapper Pipes Keep exhaust flapper pipes dry, quieter, and working longer with a purposebuilt waterproof cap. Designed for generator sets, tractors, and similar equipment, this exhaust cover prevents water intrusion, reduces flapper noise, and installs quickly for reliable, lowmaintenance protection. Key benefits Protects equipment: Prevents rain and moisture from entering exhaust flapper pipes, reducing corrosion and operational problems caused by water ingress. Reduces noise: Helps dampen flapper and exhaust noise during idling and shutdown, improving operator comfort and reducing disturbance in work sites and residential areas. Simple installation: Designed for quick fitment to flapperstyle exhaust pipes so installation is fast and straightforward during routine maintenance. Durable and weather resistant: Built to withstand outdoor exposure and regular use so it continues to perform under wet conditions. Broad compatibility: Intended for use with generator exhausts, tractor exhaust flappers, and other similar pipe outlets. Function and performance Waterproof cap design channels rain away from the pipe opening to keep internal components dry. Noise reduction comes from covering the flapper outlet and limiting direct sound escape paths without affecting normal exhaust flow when in use. Lowmaintenance solution that minimizes downtime and routine repairs related to water damage. Compatibility and size Made to fit flapperstyle exhaust pipes commonly found on portable generators, stationary generator sets, tractors, and agricultural engines. Compact cap profile designed for standard flapper pipe diameters; check your exhaust outlet diameter for fit. Suitable for onroad and offroad equipment where protection from weather and noise control is required. Easy installation Install quickly during routine checks or maintenance. The cap fits over the exhaust flapper outlet and secures in place to form an effective barrier against rain and spray. No major disassembly of the exhaust system required for most flapperstyle configurations. Use scenarios Backup power generator at a residential property: Protects the exhaust flapper from rain during outdoor storage and reduces noise when the unit runs for testing or emergency use. Farm tractor parked in open sheds or fields: Keeps moisture out of the exhaust outlet during wet seasons, helping prevent corrosion and sticking of the flapper valve. Construction site generator or worksite equipment: Reduces flapper noise near occupied areas while preventing water entry during outdoor operation. What to check before Verify your exhaust outlet is a flapperstyle pipe and measure the outlet diameter to ensure compatibility. Inspect mounting area to confirm there is space for the cap profile without interfering with adjacent components. This rainproof exhaust cap is a practical, loweffort solution for protecting flapper pipes on generators, tractors, and similar equipment. It reduces waterrelated damage and lowers flapper noise while remaining easy to install and maintain.
