Quantity:
1.Application and properties
Suitable for single-acting and double-acting reciprocating rod sealing, particularly for heavy-duty conditions. It has strong extrusion resistance in a wide range of fluids and high-temperature environments.
Low friction, simple groove and can be used for special conditions such as extremely low speed, micro-stroke etc.
The seal is easy to install and generally does not require special tools.
2. Standard material
Sealing ring: filled PTFE
Square rubber ring: NBR / FKM
