## Description

CAUTION 1.The tube connectors are primarily made for air and water . Other fluid types are highly prohibited.2. The use of pneumatic connector is limited to areas that are highly prone to fire outrage3. Don't use the connections in areas whose water temperature is above 120'C4. To avoid leakages and damage,you're advised to resist the temptation of adding extra loads to the push connectorsUSER GUIDE Carefully examine the tube connectors ends for a right angle cutting. Don't also forget to check the external connectors surface for any scratch.You need to consider the following guidelines during installationsFix the air hose connector into the joint ; there are two sections around this region namely : 1 Locking claw2 Sealing ring : it's important to insert the tube into this ring.Use sleeve for fittings connection and disconnection.Note that the sleeve is an oval shapedplumbing material that is essentially used for assembling and disbanding purpose. The round sleeve is available for any plumbing needs.On the other hand, there is limited space for the oval sleeve. Once the connection has been established ,pull the connectors to confirm their firmness.Use the right tool to tighten the external hexagonal and internal hexagonal parts of the tubefitting. It's crucial for you to use the approved torque on screws. The use of other types oftorque can damage thread and further lead to leakages . Low quantity of torque can as well leadto loosen screw and leakages.Adjust the tubes direction after the screws have properly the tightened. In a situation where theadjustment is quite difficult to achieve,use the recommended torques to change the direction ofthe tubing.

Review: Works well as described. The tubing stays securely under pressure as should be. Also there were no leaks.
Review: Works perfectly on the air suspension on my 2003 mercedes e55. Works just like air brake fittings on big rigs

*by A***R on 17 September 2025*

High quality. They have No center post so I was able to connect two 1/4” OD air lines together even though they had different ID measurement. One had double the thickness wall so the ID was very small and would not work with a center post.
