FSKR-X Pump Hydraulic Peek Spring Energized Seals
FSKR-X
Quantity:
1. Application and properties
Suitable for reciprocating piston rod or piston single-acting seal, which has good sealing performance at high and low pressure.
The working pressure 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, 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.
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 requirment /APS

5. Marking method
Marking it with the dimension of installation groove as below：
FSKR“Groove Diameter/Bore Diameter D” × “Rod Diameter d” × “Groove Width L” - “Spring Material” X Shape
For example: FSKR100×90×7.5-316X means “Bore and rod dual-use Variseals with oblique spiral-shaped Spring，Working Dimension：Rod Dia.90，Groove Dia. /Bore Dia. 100，Groove Width 7.5，Spring material SUS316
