Sierra Exhaust Elbow Gasket 18-2854-1-9, Open Riser Gasket, Replaces Barr 01-0107, Pack of 2

The Sierra 18-2854-1-9 is an open-style exhaust elbow gasket sold in a pack of two, built to meet or exceed the quality of the original equipment part it replaces. It is designed for use with exhaust manifold and riser assemblies on Volvo Penta exhaust manifold systems, sealing the connection between the exhaust elbow and riser to prevent exhaust and water leaks at this joint.

This is the open-gasket configuration, distinct from the blocked-gasket version used on different riser setups. It is compatible with Sierra risers 18-1939, 18-1999, and 18-1907, and with Sierra manifold 18-1997-1. The gasket is also included as a component of the Sierra 18-4364 open-gasket mounting kit, so it can be sourced individually for a straightforward gasket-only replacement or as part of a complete mounting kit rebuild. Each pack of two lets you service a matched pair of risers or keep a spare on hand for future maintenance.

Round in shape and silver in color, this gasket cross-references directly to Barr part number 01-0107, making it a straightforward drop-in replacement for boat owners and marine technicians who already run that part number.
