Additional Features:
The Bosch 87167711550 is a replacement O-Ring supplied in a pack of ten, used to form a watertight and gas-tight seal at threaded connections, valve bodies, pump fittings, and heat exchanger unions within compatible HVAC units. Each ring measures 13.87 mm inside diameter with a 3.53 mm cord thickness, giving it a substantial round cross section that compresses evenly into its groove and holds steady contact pressure as the assembly heats, cools, and vibrates during normal operation. The black elastomer construction is molded as a single continuous piece with a smooth, uniform sealing surface free of seams or flash, so the ring seats fully in its recess without the leak paths that develop once a seal becomes distorted, flattened, or hardened. Because these components lose elasticity over time, the ten-piece quantity lets a technician renew every affected seal in one service visit and keep spares on hand for future maintenance.
