Full model list at the end of this description.

⚙️ Key Features

• Resistant to the designated fluid and operating temperature
• Designed for the original groove or flange
• Exact joint position must be confirmed
• Quantity varies by assembly, most commonly two

🔌 Function

Seals the joint it sits in, squeezed into its groove so that the pressure difference across the joint is held by the ring rather than by the metal faces touching.

⚠️ Common Signs of Failure

• Seepage or a wet ring of dirt around the joint
• Fluid level falling steadily with no external damage to account for it
• A leak that appears only once the engine is up to temperature and pressure
• On removal the ring is found hardened, swollen or flattened, with a permanent groove pressed into it

🛠️ Service Notes

• Renew the ring whenever the joint is dismantled, and check the groove and the mating bore for scoring or corrosion before reassembly
• Lubricate the new ring with clean fluid of the type the joint carries so it rolls into place instead of twisting
