Description

The 2.1/2″ Counterweight Style Exhaust Rain Cap (MPN 311 212) is a clamp-on cover for vertical exhaust stacks that keeps rainwater out of your engine and silencer. Built from heavy-duty steel with a corrosion‐resistant finish, it uses a counterweight flap that opens with exhaust flow and closes when the engine stops, sealing the pipe against water ingress. This helps prevent internal rust, contamination and potential engine damage, supporting reliable starting and longer component life. Sized to fit 2.1/2″ (63.5 mm) outside-diameter exhaust pipes, it suits a wide range of plant, agricultural and industrial machines such as tractors, excavators, dumpers, rollers and generators used outdoors.

Key Features:
– Fits 2.1/2″ (63.5 mm) outside-diameter exhaust stacks
– Counterweight action for automatic opening during running and closing when stopped
– Robust steel construction with a weather-resistant finish for long service life
– Effective barrier against rainwater to reduce corrosion and water ingress
– Clamp-on installation; supplied with a clamp for straightforward fitting
– Smooth, positive flap movement for reliable operation in daily use
– Suitable for vertical exhausts commonly found on plant, agricultural and industrial equipment
– Low maintenance design; easy to remove for inspection or servicing
– Helps protect engines, turbos and silencers from moisture-related damage
– Practical upgrade for machines stored or operated outdoors

Typical Applications:
Used on tractors, telehandlers, excavators, dumpers, rollers, compressors, generators, pumps, forestry chippers and other machinery with vertical 2.1/2″ (63.5 mm) exhaust stacks. Ideal for equipment working or parked in the open, on construction sites, farms, yards and depots. Helps maintain reliability during wet weather and reduces downtime caused by water entering the exhaust system.

Also known as:
Exhaust rain flap, stack cap, weather cap, exhaust flapper, muffler rain cap, exhaust cover, rain guard, stack cover, exhaust lid, exhaust protector. These terms all describe the same counterweight‐closing cap designed to keep rain out of an exposed exhaust pipe.
