Details
1. Application and properties
Suitable for one-way and reciprocating rod seal. It provides good sealing performance at high, medium, and low
pressures. The working pressure range is wide and pressure resistance can be enhanced by adding a back-up ring
The friction coefficient is small, the contact pressure with the matching surface is low, the friction with the matching
surface is small and it can work with or without lubrication. It has good wear resistance and long 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 in special working conditions such as
extremely high speed, extremely low speed, and micro-stroke.
The spring is a oblique spiral type, and the spring force remains constant within a larger deformation range, so it
can be used in working conditions with some eccentricity. The cross-sectional shape of the spring is elliptical, which
provides good lip support for the sealing component and has a long sealing life.
Suitable for sealing groove sizes in aviation, military and industrial field. The installation groove is small and 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 requirement /APS
