⚙️ Key Features

• Genuine Volvo Penta OEM ring
• OEM part number 20513745
• Technical distinction: Single-use compression cutting ring for a matched rigid pipe and union; approximate listed weight 0.004 kg; Volvo product group 2520, function group 1159

🔌 Function

Compresses into the matched union to grip and seal the rigid pipe connection. Clean and inspect both sealing surfaces, renew the seal whenever the joint is opened, avoid twisting or cutting and tighten the joint evenly to specification.

⚠️ Common Signs of Failure

• Visible oil, coolant, fuel or air leakage at the sealed joint
• Loss of pressure, vacuum or fluid level in the connected system
• Contamination passing across the seal or entering the assembly
• Seal hardened, cut, swollen, flattened or displaced
• Repeat leakage caused by a damaged groove, shaft or mating face

🛠️ Service Notes

• Renew rather than reuse: rings of this kind seal or retain by being sprung or compressed into place and take a permanent set once fitted
• Clean the groove, register or bore the ring sits in and remove any burr or old sealing residue before fitting — debris in the groove stops a ring seating and is a common cause of a repeat leak
• Open or compress the ring only as far as it needs to go on; overstretching or twisting it during fitting distorts it permanently
• Check the ring is fully seated all the way round its groove or register, and the right way round where its faces differ, before closing the assembly up
