🔧 Product Description

Genuine Volvo Penta o-ring supplied in the gasket kit and available separately under this number, listed for 361 applications across the MD, D, TD, AQ, AQD and TMD families - the widest fitment of any o-ring in this group. It supersedes 833278, which was catalogued earlier as a thermostat housing, so on older engines the seal alone now covers what was once ordered as a housing.

🚤 Compatibility

  • Engine Family: MD, D, TD, AQ, AQD, TMD, AD, TAMD, AQAD, TSK, BB, MS, B, IPS, DP, SP, DPX, HS, S, PJX, PT, MB, KAD, KAMD
  • HP Range: 75-480 HP

Full model list at the end of this description.

⚙️ Key Features

  • Included in the gasket kit
  • Supersedes 833278, previously catalogued as a thermostat housing
  • 361 applications across six engine families
  • Available as a single ring
  • Quantity varies by assembly, most commonly one

📋 Kit Contents

  • Included in gasket kit.

🔌 Function

Seals the joint between two faces, squeezed into its groove to hold coolant or oil in.

⚠️ Common Signs of Failure

  • Coolant or oil weeping at the joint
  • Ring hardened, flattened or gone shiny
  • Nicks or splits from assembly damage
  • Swelling or softening from the wrong fluid
  • Slow coolant loss with no obvious drip

🛠️ Service Notes

  • Because 833278 was a housing rather than a seal, an order raised against the old number may leave you short of the housing itself - check what is actually damaged
