The Aeroflow AERFCM3474 #6 O-Ring is a sealing element sized for -6 AN fitting connections in fuel, oil, and coolant plumbing systems. It is engineered to deliver a dependable seal at threaded and flared fitting interfaces where fluid containment is critical. Having the correct o-ring on hand during plumbing assembly or service prevents costly leaks and system downtime.
Manufactured from Nitrile (Buna-N) rubber, these o-rings resist degradation from petroleum-based fluids, hydraulic oils, and a broad range of commonly used chemicals. The material maintains its elasticity and compression characteristics across the temperature and pressure fluctuations typical of automotive and light industrial fluid systems. Each ring is precision-molded to match -6 AN port dimensions, ensuring uniform seating and consistent sealing force.
This 10-pack gives technicians, fabricators, and hobbyists a ready supply of replacement seals for ongoing projects and routine maintenance. The o-rings are compatible with fuel system fittings, oil line connections, coolant plumbing, and pneumatic circuits that accept -6 AN hardware. Keeping a set like this in your parts inventory means you are prepared for new builds and emergency repairs alike.
