1.Application and properties

Suitable for rotating single-acting pressure bars/shaft seals, and can also be used for reciprocating and rotating composite motion rod/shaft seals, with excellent sealing performance in high, medium and low pressure situations.

The friction coefficient is small, and the contact pressure with the mating surface is low. It can work with or without lubrication, and it is wear-resistant with 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 and micro-stroke,.

Suitable for aerospace, military and industrial sealing groove sizes, with small installation grooves and open grooves.

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

5. Marking method:

Mark with the dimension of installation groove as below：

FSXL “Rod Diameter d” × “Groove Diameter D” × “Foot Diameter D1” × “Groove Width L” (Foot Height H1”)- “Spring material and shape”

For example: FSXL160×170×177.5×7.1(2.05)-316X means Groove dimensions d=160, D=170, D1=177.5, L=7.1, H1=2.05, Spring material 316, Oblique spiral shape
