How to avoid leakage or looseness during installation?
1. Preprocessing: Ensure that the pipe end is cut flat, deburred, and avoid scratching the O-ring< 2. Insertion depth: The pipe should be inserted to the bottom and a "click" sound should be heard (snap lock)< 3. Stress test: After installation, perform a low pressure test and gradually increase the working pressure< 4. Do not rotate: Some quick connectors are not allowed to rotate after connection to avoid wear on the sealing ring
How to choose a suitable quick plug connector?
1. Pipe compatibility: For hard pipes (such as stainless steel pipes) or flexible pipes (such as PU pipes), ensure that the joint supports the corresponding outer diameter (OD) of the pipe< 2. Medium type: water, oil, gas, corrosive liquid, etc. Choose matching sealing materials (such as NBR oil resistant, PTFE acid and alkali resistant)< 3. Pressure/temperature range: ordinary joint pressure resistance ≤ 1.6MPa, high-pressure type can reach 10MPa; The temperature range is limited by the sealing material (such as -20 ° C~150 ° C)< 4. Interface standard: The threaded end can be selected from NPT, BSPP, G thread, etc., and should match the device port
How to achieve fast connection and sealing with quick plug connectors?
1. Connection mechanism: The pipe is locked by internal spring buckles (such as steel balls or claws), which spring open when inserted and automatically rebound and lock in place< 2. Sealing method: O-ring (fluororubber, EPDM, etc.) compression sealing is usually used, and some designs have conical metal seals< 3. Disconnecting operation: Press or pull the collar (such as single key/double key structure), release the buckle to separate
What are the installation steps for stainless steel quick connect fittings?
(1) After cutting off the trachea, remove the burrs and insert one end of the trachea into the joint socket (be sure to insert it to the bottom) to achieve a firm connection and sealing effect. (2) After repeatedly pulling out the trachea. The worn part at the end should be cut off Continue to use after leveling. (3) When disassembling the trachea, press the connector sleeve in with your thumb and gently apply force to pull out the trachea. (4) Terminal pipe joints such as right angle, three-way, four-way, etc. After installation, simply rotate the adapter body to adjust the direction of the joint connection
