OVERVIEW & BENEFITS

The High-Pressure Bonded Sealing Washer (93786A150) is designed to provide a leak-tight seal under high-pressure conditions. Constructed with a zinc-plated steel outer ring and a Buna-N (Nitrile) rubber sealing core, this washer combines strength with reliable sealing performance.

Sized for M8 screw heads, this bonded washer is commonly used in pressure washing equipment, hydraulic systems, pumps, and fluid connections where vibration and pressure can cause standard washers to leak. The metal outer ring prevents over-compression while the Buna-N insert creates a tight, durable seal.
