INTRODUCTION OF QUICK CONNECTOR
1) the design and production
Innovative, secure and quick, Our quick connect fittings made of synthetic material are suitable for most media carrying lines. Be it fuel , oil vapor , water cooling and air carrying lines . We offer the idea means of connection. These quick connectors are specially suited to being matched up with the automotive pipe system.
The design and production of quick connector are strictly accord with SAE J2044-2009. Quick connect coupling specification for liquid fuel and vapor or emissions systems . If the product does not meet customer needs, we can design and manufacture according to customers requirements. Plug-in and sel-locking structure enables connect and disconnect more quick and easier. The space required for the operation is only the width of a finger on both sides. These features ensure quicker connector can be high-density arrangement and an increase in customer design flexibility.
2) Security of quick connector
Quick connector with double sealing rings radial sealing structure, modified rubber o-rings used, mainly for fluid The physics chemistry, custom, anti-aging, corrosion, and swelling; outer o-rings are separated by the intermediate spacer ring. Corresponding space on the two sealing ring, rubber substrate bonding does not occur, the outer synthetic rubber o-rings used, Increased mechanical properties. preventing air aging. Sealing ring and spacer ring through the outer ring of elastic clamping device securely fastened in Shell will not result in phenomena such as ring falls of, and shift. Great seal security is guaranteed.

5) Connect &disconnect peration method of quick connector
Quick connector is made up of body , in o-ring , out o-ring , spacer ring , securing ring and locking spring . When a mating tube end piece inserts the connector , as locking spring has certain elasticity , Tie clip fastener to connect two connectors together ,and then pull back to assure complete connection.; Repair or remove the quick connector is difference . first advance push the male connector and press the clip button , lock expansion , you can easily pull out the connector ;please note,SAE 30th heavy oil lubrication should be used before Reseat
The Step of inserts the connector 
The Step of pull out the connector
