Breather Clamp-ON 1-3/4in Mount

The Breather Clamp-ON 1-3/4in Mount is a precision engine breather solution designed for serious automotive enthusiasts and engine builders who demand reliable crankcase ventilation routing. This clamp-style mounting system addresses a critical need in modified and high-performance engines: managing crankcase pressure and moisture evacuation without sacrificing underhood aesthetics or complicating plumbing runs. Whether you're building a street machine, circle-track competitor, or upgrading a stock engine to handle forced-induction demands, a quality breather clamp ensures your PCV or catch-can system stays secure and functional across engine vibration and thermal cycles.

The 1-3/4-inch clamp diameter accommodates standard breather hoses and separator outlets, providing a robust mechanical grip that won't slip or rattle under sustained RPM or lateral G-forces common to performance driving. Its compact footprint—measuring 4 inches long by 1.5 inches wide by 5 inches tall—allows flexible mounting to chassis, firewall, or engine bay structure without fouling headers, fuel systems, or spark plug access. The all-metal construction with corrosion-resistant finish withstands oil vapor, fuel vapor exposure, and temperature swings typical of engine compartments, ensuring years of reliable service whether your build runs pump gas or race fuel.

Fabricators and engine builders integrating custom PCV systems, catch cans, or oil separators will appreciate the universal design that accepts any standard 1-3/4-inch diameter hose stub. Installation requires only basic hand tools and a mounting point—drill a hole or weld a tab to your chosen location, slide the clamp over your breather outlet, and tighten securely. Weighing just 0.17 pounds, this clamp adds negligible mass while delivering the security needed to keep your crankcase ventilation system isolated from engine movement and road vibration.
