Product name: Polyurethane Y-type seal PU air seals
Usage: Y type can be used for piston and piston rod sealing, and has a wide range of applications in various mechanical equipment. The groove design can be according to Chinese standard HG4-335 .
Working pressure: ≤200bar
Operating temperature: standard type ( NBR ) -30~+120 ℃
Reciprocating speed: ≤0.5m/s
Medium : (NBR) general petroleum-based hydraulic oil , water glycol hydraulic oil , oil-water emulsified hydraulic oil , (FPM) general-purpose petroleum-based hydraulic oil , phosphate ester hydraulic oil , water , gas .
Install ;
In order to avoid damage to the sealing lip , measures should be taken to avoid sharp edges during installation . In the case of large pressure changes and high speeds , such seals are usually fixed in the groove with a backup ring .
Material :
The standard material is nitrile rubber of 80 degrees . According to different uses such as hydraulic and pneumatic, the material of Y type is nitrile of 65~95 degrees, and fluorine rubber of 65-85 degrees is optional
