The JB982-77 Combined Sealing Washer is a precision-engineered,Composed of a metal gasket and rubber, it uses oil as the medium and is used for sealing threaded pipe joints and plugs. Its operating pressure is 400 kgf/cm² (39.2 MPa) and operating temperature ranges from -25℃ to 80℃. The gasket is a component placed between the connected part and the nut, usually a flat metal ring. It serves to protect the surface of the connected part from scratches by the nut and distribute the pressure of the nut on the connected part.

• Two-in-One Design: Combines the functions of a flat washer and a sealing washer, simplifying the assembly process.
• All-Metal Construction: Made of stainless steel, suitable for extreme temperature and pressure environments.
• Pressure-Activated Sealing: The sealing lip deforms under bolt torque to form an airtight or liquid-tight seal.
• Reusable: Can usually be reused multiple times if within the deformation limit, reducing lifecycle costs.
• Wide Compatibility: Resistant to corrosion, radiation, and most highly corrosive chemicals.

It is widely used in hydraulic and pneumatic systems, construction machinery and other fields. It is suitable for working conditions with sealing surface deviation or vibration, ensuring sealing reliability.
