🔌 Function

The gasket seals the exhaust elbow / riser joint while allowing full cooling-water flow through the open gasket ports. Using the wrong gasket style can restrict cooling flow or create an incorrect water path.

Common signs of failure:

• Rust staining around riser joint

• Exhaust leak or ticking noise

• Water leakage at gasket face

• Riser removed during exhaust service

• Gasket crushed, split or delaminated

• Incorrect restricted gasket fitted in a full-flow layout
