Exhaust, Vents and Caps

Where your system meets the sky. After-the-fan stack caps, no-loss rain caps, and vent fittings exhaust air cleanly while keeping weather, backdraft, and debris out of your ductwork.

Exhausts, vents, and caps are where your duct system meets the outside air — and where a poor design leads to rain intrusion, backdraft, or lost system pressure. US Duct's after-the-fan stack caps, no-loss rain caps, and vent fittings are engineered to exhaust air cleanly while keeping weather and debris out. Gas and jet caps and related fittings round out the exterior transition points of your system, protecting both performance and equipment longevity.

No-Loss Rain Protection

No-loss rain caps protect system performance while keeping weather out.

Prevents Backdraft & Loss

Engineered exterior fittings prevent backdraft and pressure loss at the stack.

Shields Downstream Equipment

Protects downstream equipment and ductwork from weather-related damage.
