This is an O-ring, a circular sealing element designed to prevent fluid or gas leaks between two mating surfaces.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
O-rings are common in heavy-duty truck and trailer systems such as air brake fittings, hydraulic connections, fuel line couplings, and air conditioning components. They are replaced when they show signs of hardening, cracking, deformation, or loss of elasticity to ensure a leak-free seal.
