6 Inch Counterweight Exhaust Rain Cap Matte Black Exhaust Flapper Cap for Tractor Heavy Machinery

The flap on a 6 inch cap is heavy, and at this size gravity alone is unreliable in gusty conditions on a rooftop. Our answer is a deeper counterweight arm and a wider flap seat, so the flap seats on a machined ring and stays there. The matte black coating matches typical plant-room exhaust lines and hides the condensate staining that shows up quickly on bright metal at this diameter.

• High-Strength Carbon Steel Base Material Made of thick carbon steel, sturdy and not easy to deform. Excellent mechanical strength to withstand strong wind, vibration and frequent shaking on construction vehicles and farm machinery.
• Black Powder Coating Finish Uniform matte black spray coating, great wear resistance, scratch resistance and rust resistance. Effectively resists corrosion from rain, mud, fertilizer and dust in farm and construction sites. The smooth coated surface is easy to clean.
• Clamp-On Quick Installation Equipped with an adjustable hose clamp. Fits vertical exhaust stacks of different diameters. No complicated welding required — fast to mount and remove, convenient for maintenance.
• Wide Adaptation for Vertical Exhaust Stacks Designed for vertical exhaust outlets, will not affect normal exhaust efficiency while providing reliable weather protection.

This black coated carbon steel automatic exhaust flapper rain cap is widely used for large farm tractors, combine harvesters, excavators, wheel loaders, bulldozers, heavy-duty trucks, diesel generators and other off-road heavy machinery.

Ideal for farmland, construction sites, mining yards, logistics yards and other harsh outdoor working environments. It is an essential exhaust stack accessory to protect diesel engine exhaust systems during long-time outdoor parking.
