🔌 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
