Automotive air conditioning O-rings you know?

??Is an automotive air conditioning system in a car, automotive air conditioning O-ring hydraulic and pneumatic systems are the most widely used seal. Automotive air conditioner is an O-ring seal extrusion, extrusion seals rely on the basic principle of the seals is elastically deformed, the contact pressure caused by the sealing member contact surface, the contact pressure greater than the pressure within the sealed medium side It does not leak, otherwise leakage occurs.

??Automotive air conditioning O-rings according to the national standard GB3452.1 series design, automotive air conditioning O-ring groove through the gap to comply with the relevant provisions of automotive air-conditioning to prevent O-ring being squeezed in the gap. Warp space and system pressure sealing element, automotive air conditioning O-ring cross-section diameter, automotive air conditioning O-ring cross section are inextricably linked

??Automotive air conditioning O-rings designed properly, will not only affect the performance of automotive air conditioning O-ring, it will increase the degree of damage.

??Xinhua Xu customer as a starting point to further improve infrastructure to provide high-quality quality, service behavior, truly satisfied customers be assured.
