Product description

The lipped gasket (NSW 20-30-6) is a high-performance sealing component designed for use in the hydraulic and pneumatic systems of Snap-On automotive equipment. This gasket features a specialized lip design that creates a tight, dynamic seal against moving parts, such as a piston or shaft. The 20-30-6 dimensions refer to its inner diameter, outer diameter, and thickness in millimeters, ensuring a precise fit for specific Snap-On tool applications. Sealing integrity is paramount in shop equipment; a leaking gasket can cause a loss of pressure in a hydraulic jack, a failure in a tire changer's air cylinder, or an oil leak in a wheel balancer's drive system. This gasket is manufactured from durable elastomeric materials that are resistant to hydraulic fluids, oils, and the varying temperatures found in a workshop. By maintaining a perfect seal, this part prevents contamination of the internal systems and ensures that the equipment can generate and maintain the forces required for heavy-duty automotive work.

Product highlights
