Details
1. Application and properties
Suitable for one-way and reciprocating piston seal, especially for fast response cylinders in control cylinders, servo
cylinders, machine tools, and construction machinery.
Low friction coefficient, wear-resistant, long service life. Can work with or without lubrication, and can be used for
oil-free lubrication cylinder sealing. The adaptability to working medium and working temperature range can be
changed by replacing the O-ring material. Can be used in special working conditions such as extremely high speed,
extremely low speed, and micro-stroke.
Suitable for integral pistons and the installation groove is small.
Complies with GB/T 15242.1-94 and GB/T 15242.3-94 standards.
Good extrusion resistance and larger installation clearances than general sealing components.
Different cross-sectional products can be selected according to the actual working pressure value. In principle, the
larger the working pressure, the larger the cross-sectional product should be selected
2. Standard material
Sealing ring: filled PTFE
O-Ring: NBR / FKM
