PTFE piston seal specifications

PTFE piston seal specifications are designed to meet the needs of high-performance hydraulic and pneumatic systems where low friction and chemical resistance are essential. PTFE offers excellent dimensional stability, wide temperature tolerance, and compatibility with aggressive media. These specifications outline pressure ratings, surface finish requirements, groove dimensions, and operating speed limits. For OEMs and system designers, adhering to PTFE piston seal specifications ensures optimal efficiency, reduced stick-slip, and long-term performance in precision cylinders and automation equipment.

Dustproof Seal

The dustproof seal is a single-acting seal that is installed by extruding the outer diameter. It can effectively prevent dust and dirt from entering, and allow the residual oil to flow back.
