17515231 O-Ring | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta o-ring is a precision fluid-sealing component used in the fuel-filter or fuel-system sealing joint. It is manufactured to the original Volvo dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. In service, it seals the matched fuel-system connection against diesel leakage and air ingress. Selection must be confirmed by OEM part number 17515231, the exact engine/product model, serial number and installed configuration.

🚤 Compatibility

• Engine Family: D, TAD, TWD, TADH

⚙️ Key Features

• Genuine Volvo Penta OEM o-ring
• OEM part number 17515231
• Clean and inspect the shaft, groove and mating surfaces; lubricate only where specified and install without twisting, cutting or contaminating the seal.

🔌 Function

The O-ring sits in a groove and is compressed on assembly, deforming to fill the gap between two mating surfaces and block leakage. Its elasticity maintains sealing contact as pressure and temperature vary.

⚠️ Common Signs of Failure

• Fluid weeping, seeping or dripping at the joint
• Hardening, cracking or loss of elasticity on removal
• Flattening or permanent set so the ring no longer springs back
• Swelling or chemical attack from the fluid it seals
• Nicks, cuts or twisting from incorrect installation

🛠️ Service Notes

• Always fit a new O-ring — never refit one that has been removed, as it has already taken a set in its groove
• Clean the groove and both sealing faces and check them for nicks, scoring and corrosion pitting; a damaged groove will leak however good the new seal is
• Smear the ring with a little clean lubricant compatible with the fluid it seals, then roll it into place by hand so it sits untwisted and fully in its groove
• Never lever an O-ring over a sharp edge or thread with a screwdriver; use a blunt plastic tool and protect any edge the ring has to pass
• Assemble the joint squarely and tighten to the figure and sequence given in the workshop manual for your engine — over-tightening extrudes the ring and causes the very leak you were curing
