Its job is to create a leak-proof barrier between two mating surfaces in static or dynamic joints, keeping fluids like oil, fuel, or coolant inside your engine or hydraulic system. You replace it whenever you disassemble a sealed connection, or if you spot a leak caused by a hardened, cracked, or worn-out ring. This particular ring is made from FKM (Viton) with a PTFE coating, which gives it strong resistance to high heat, abrasion, and a wide range of truck fluids.
