Rod Seal UPH

UPH type can be used for piston and piston rod seals. This type of seal has a large cross-section and can be used for a wide range of operations. The nitrile rubber and fluororubber materials used can ensure a wide range of operating temperature. range of use.

NBR O Rings UPH Application:

Working pressure: ≤32MPa, in order to prevent extrusion, when the pressure is higher than 15MPa, it is recommended to use a retaining ring at the root, which can ensure a large gap during normal operation.

Working temperature: 

standard type (NBR) -30℃～+100℃

Heat-resistant type (FPM) -10℃～+150℃

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.

UPH Gasket Ring Installation:

Such O Ring Seals shall have an axial clearance (see columns h and H in the table). To avoid damage to the sealing lip, precautions should be taken during installation to avoid sharp edges.

Material:

The standard material is nitrile rubber, Shore Hardness (SHA) 90°.
