304 Stainless Steel Exhaust Stack Rain Cap with Counterweight Flap and Bumper Block for Tractor Exhaust Pipe

Heavy-duty 304 stainless steel exhaust stack rain cap designed for tractor exhaust pipes. The built-in counterweight flapper opens automatically with exhaust airflow and closes tightly when the engine is idle. Equipped with a bumper block to cushion impact when the cap drops, it keeps rain, leaves, debris, and small animals out of your tractor exhaust system.

• Premium SUS304 Stainless Steel Construction

  Made of solid 304 stainless steel, rust and corrosion resistant. It stands up to harsh outdoor farm environments and long-term high-temperature exhaust from heavy tractors without deformation or rusting.

• Precision Counterweight Flapper Hinge — Automatic Opening & Closing

  The balanced flapper hinge enables smooth automatic operation. Exhaust gas pressure lifts the flap open during engine running; the weighted flap falls and seals tightly once the engine shuts down. No spring design means fewer failure points.

• Bumper Block for Impact Cushioning

  Comes with a dedicated bumper block at the hinge mounting area. It effectively absorbs and relieves the impact when the rain cap flap closes, reducing metal clanging, avoiding wear on the exhaust stack, and extending service life.

• Excellent Protection for Tractor Exhaust

  The sealed closed flap blocks rainwater, fallen leaves, dust debris, birds, and small critters from entering the exhaust pipe. Prevents internal rust, clogging, and engine damage caused by foreign objects.

• Easy & Secure Adjustable Installation

  Clamp-on adjustable mounting structure fits standard tractor exhaust stacks. Quick to install without complicated welding. Stable locking ensures the cap will not shake or fall off during tractor operation.

Specially designed for heavy-duty tractors. Also compatible with diesel generator sets, construction machinery, and other equipment exhaust stacks with matching pipe diameters.
