Sierra Exhaust Elbow Gasket 18-2819-1-9, Replaces 27-39915, for Elbow 18-1973, Pack of 2

The Sierra Exhaust Elbow Gasket 18-2819-1-9 is a two-piece pack of gaskets designed for use with exhaust elbow 18-1973. Each gasket is made from a stainless steel infused graphite material engineered for superior compressibility, helping the gasket seal effectively against the pressures and heat cycling found in a marine exhaust elbow joint. A tight, consistent seal at this connection point helps prevent exhaust leaks and the corrosion that can follow when combustion gases or water escape past a worn or hardened gasket.

This gasket is the component specified for elbow 18-1973 and is also included as part of mounting kit 18-8508. It corresponds to OEM reference number 27-39915, so it can be used as a direct replacement when that number is called for. Sierra backs this gasket with its standard product warranty, and each package contains two gaskets so a spare is on hand for the next service interval.
