Features
1.It is applied to hydraulic system from middle load to high load.
2.antiextrusion characteristics is improved greatly.Long service life
3.Good Shape stability ,high wear resistance,good chemical stability
4.Excellent sliding performance,no creeping phenomenon
Do not open the seal package if unnecessary, otherwise the dust will stick to the seal or scratch it.
Store in cool place, not on sunlight place. UV and moisture will accelerate the deterioration of rubber and plastics and dimensional changes
Carefully pack, store unpackaged product, do not glue or put into impurities, keep the original state. Keep the Nylon seal package close to prevent moisture cause dimensional changes
Do not put seals near heat sources, such as boilers, stoves. Otherwise heat will accelerate the aging of seals
Do not put seals near the motor and other place where produces ozone
Do not use a needle, wire, rope hang seals, otherwise, would cause the seal deformation, damage the lip
Sometimes, there are color change or white powder on the seal surface (frost phenomenon), this will not affect the performance of the seal
Application
(1) Full of elasticity and resilience;
(2) Appropriate mechanical strength, including expansion strength, elongation and tear resistance.
(3) The performance is stable, it is not easy to swell in the medium, and the thermal shrinkage effect (Joule effect) is small.
(4) It is easy to process and shape, and can maintain precise dimensions.
(5) Does not corrode the contact surface, does not pollute the medium, etc.
The most suitable and commonly used material to meet the above requirements is rubber, so the sealing ring is mostly made of rubber. There are many types of rubber, and new types of rubber are constantly appearing. When designing and selecting, one should understand the characteristics of various rubbers and choose them reasonably.
