Home Appliance Used Compact Double Springs Variseals Seals FSVI-X
FSVI-X
Quantity:
1. Application and properties
Suitable for static end-face sealing or rotary sealing to prevent pressure fluid from leaking from the outside to the inside, with good sealing performance at low, medium and high pressures.
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 high speed and extremely low speed.
It is suitable for sealing groove sizes in aviation, military and industrial fields. The standard installation groove is the same as the standard O-ring installation groove, with small size. It can also be designed as non-standard parts to meet the sealing requirements of any size groove. The groove is 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/APS
