Details
1.Application and properties
Suitable for one-way and reciprocating piston seal. It has good sealing performance at high, medium and low
pressures, especially suitable for low pressure and low temperature conditions. The work pressure adaptation range is
wide, and the pressure resistance can be enhanced by adding back-up rings.
The friction coefficient is small, the contact pressure with the matching surface is low, and the frictional force is
small during operation, can work with or without lubrication. It has wear-resistant and has a long service life. The
working medium of the sealing sleeve is widely adaptable, and other chemicals do not react with it except soluble
alkali metal, high temperature fluorine gas and chlorine trifluoride.
Operating temperature range from -200°C to +250°C, and it can be used for special working conditions such as
extremely high speed, extremely low speed, and micro-stroke
Suitable for aviation, military and industrial sealing groove size. Small installation groove and the groove is open
or semi-open.
Flexible size change, wide adaptability, can be designed for any size of the installation groove of the seal, non
standard part design is very convenient.
2. Standard material
Sealing ring: filled PTFE
Spring: SUS301, 302, 304, 316 or 718 Default use SUS301, please specify if there are special requirement/103A
