Details
1. Application and properties
It is composed of three parts. The rubber star-shaped ring is in the middle of the top, the rubber O-ring is at the
bottom, and the filling PTFE sealing sliding ring is in the middle.
Suitable for two-way and reciprocating piston seal. It has dual safety with low friction and high elasticity, and good
dynamic and static sealing performance. It allows for larger extrusion clearances while also having pressure retention
capabilities. It has good dynamic and static sealing performance with minimal leakage in the cylinder. It is suitable for
cylinders with strict requirements for position or pressure retention and relatively slow movement speed (<0.5m/s),
such as pressure machine cylinders, support cylinders, positioning cylinders, piston-type accumulators, etc.
It has low friction coefficient and good sliding performance without crawling phenomenon. It can adapt to a wide
range of working media and working temperature range by changing the material of O-ring and star-shaped ring. It
is suitable for integral piston and the installation groove is small.
Compliant with GB/T 15242.1-94 and GB/T 15242.3-94 standards.
2. Standard material
Sealing ring: filled PTFE
X-Ring: NBR / FKM
