?The use of the hydraulic seal performance

??Hydraulic seals the use of performance requirements seal leak amount is very small, has good sealing effect, and with the increase of the hydraulic oil pressure to automatically improve their sealing effect, even under the bad working environment, hydraulic seal leak amount is no obvious increase.

??Good compatibility for hydraulic seals long soak in the hydraulic oil, swelling, dissolved, or embrittlement harden extremely easily, sealing function loss, so the hydraulic seal of the hydraulic oil has good compatibility.

??Small friction resistance to avoid or reduce hydraulic equipment produce the bad phenomena, such as low pressure crawling for hydraulic seals has lower static friction resistance and friction resistance, and its friction coefficient should be very stable.

??Long life of the hydraulic seals should have good flexibility, heat resistance, cold resistance, pressure resistance, wear resistance and certain physical and mechanical strength etc., and long service life.

??Hydraulic seals cheaper relatively easy to manufacture and installation, the seal grooves corresponding also convenient processing and manufacturing, the sealing surface machining accuracy requirements are relatively low, so the price is cheap.
