JB982 Combination Sealing Washer
JB982 combination sealing washer is a specialized sealing fastener component designed to provide reliable sealing performance and prevent leakage in hydraulic, pneumatic, mechanical, and industrial systems. The JB982 combination sealing washer combines a metal support ring with an elastic sealing element, creating a compact sealing solution that maintains pressure resistance and improves connection reliability.
Manufactured with high-quality metal materials and sealing rubber components, the JB982 combination sealing washer offers excellent sealing performance, vibration resistance, and durability. It is widely used in hydraulic equipment, automotive systems, engineering machinery, pumps, valves, and industrial fluid control applications.

Product Overview
The JB982 combination sealing washer is engineered for threaded connections requiring both mechanical fastening and fluid sealing. Its integrated structure consists of a precision metal washer bonded with an elastomer sealing ring, allowing it to withstand pressure while preventing oil, air, and liquid leakage.
Compared with traditional flat washers, the JB982 combination sealing washer provides improved sealing capability without requiring additional sealing materials. The metal component supports the sealing ring, while the elastic element compensates for surface irregularities between the bolt, screw, and mounting surface.
This design makes it a practical choice for hydraulic systems, lubrication equipment, and industrial machinery requiring dependable leak prevention.
