🔧 Product Description

A genuine Volvo Penta o-ring used in the temperature-control compressor assembly. It is supplied as an individual service component under part number 20443759 and is intended to restore the original fit, alignment, sealing, support or operating function of the specified assembly. This listing supplies the named part only; adjoining components shown in an parts list for your engine are serviced separately unless explicitly stated.

🚤 Compatibility

  • Engine Family: TAD, TWD
  • HP Range: Approximately 428 HP

Full model list at the end of this description.

⚙️ Key Features

  • Supersedes 3537507
  • Listed for 31 applications across TAD and TWD series engines
  • For the temperature-control compressor assembly
  • Supplied as a single o-ring, not as part of a kit

🔌 Function

Seals a joint inside the temperature-control compressor assembly, holding the mating faces gas- and oil-tight so pressure is not lost past the connection.

⚠️ Common Signs of Failure

  • Oily or damp film creeping out around the compressor joint
  • Cooling performance falling away as pressure escapes past the seal
  • Dirt sticking in a ring around the joint line
  • Ring found flattened, hardened or split when the joint is opened

🛠️ Service Notes

  • Fit a new ring whenever the joint is opened - an o-ring takes a set in service and will not seal a second time
  • The number replaces 3537507, so an older parts list and the current one are describing the same ring
