1. Application and properties

Suitable for end-face static sealing or low-speed rotary sealing, to prevent pressure fluid leakage from the outside, with good sealing performance in low, medium, and high pressure situations.
Low friction coefficient, low contact pressure with the mating surface, and the friction with the mating surface is the smallest among all types of seals. It can work with or without lubrication. It has good wear resistantance and 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. It can be used in special working conditions such as extremely low speed.
Suitable for sealing groove sizes in aviation, military, and industrial applications. The standard installation groove is the same as the standard O-ring installation groove, and the size is small. It can also be designed as non-standard parts to meet the sealing requirements of any size groove. The groove can be open or semi-open.

2. Standard material

Sealing ring: filled PTFE
Spring: SUS301, 302, 304, 316 or 718 Default use SUS301, please specify if there are special requirment/103A
