1.Application and properties
Suitable for rotary single-acting pressure rod seals, and can also be used for reciprocating rod seal with rotary compound movement, and has good sealing performance at high and medium pressures. The working pressure adaptation range is wide,
The friction coefficient is small, and the contact pressure with the mating surface is low. During operation, the frictional force with the mating surface is the lowest among all types of sealing components. It can work with or without lubrication, is wear-resistant, and has 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, extremely low speed, micro-stroke, etc.
It is suitable for aviation, military, and industrial sealing groove sizes. The installation groove is small and 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/400A

4. Related Dimensions
R1=0.1～0.2;R2=0.3～0.5; R3=0.3～0.5; D1,H1, Can be determined according to the specific structure installation space, C=(0.5～1.0)L; The specific values are selected according to the section size of the seal. The remaining values are listed in the table below:
| Rod | Groove | Groove | Radial |
| Diameter | Width | Diameter | Clearance e |
| d | L | D | e |
| 2～10 | 2.5 | d+3.0 | 0.05 |
| 10～22 | 3.2 | d+4.0 | 0.065 |
| 22～52 | 4.7 | d+6.0 | 0.075 |
| 48～150 | 7.5 | d+10.0 | 0.09 |
| 150～1000 | 11 | d+15.0 | 0.1 |
5．Marking method
Mark it 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)-304V means Groove dimensions d=160, D=170, D1=177.5, L=7.1, H1=2.05, Spring material 304
