🔧 Product Description

A genuine Volvo Penta o-ring used in the engine fluid or pressure sealing joint. It is supplied as an individual service component under part number 20586720 and is intended to restore the original fit, sealing, alignment, retention or operating function of the specified assembly. This listing supplies the named component only; adjoining parts are serviced separately.

🚤 Compatibility

  • Engine Family: TAD, TWD

Full model list at the end of this description.

⚙️ Key Features

  • O-ring for an engine fluid or pressure joint
  • Listed for 67 applications across TAD and TWD engines

🔌 Function

Creates an elastomeric seal between mating surfaces.

⚠️ Common Signs of Failure

  • Leakage develops at the joint
  • The O-ring is flattened, cut or swollen
  • The seal extrudes or twists
  • Contamination enters the circuit

🛠️ 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
