【APPLICATION SCENARIO】 PU connector plug and play, no air leakage. Tube push fit straight quick connect have both internal and external hexagonal functions. Quick and convenient loading and unloading with twist and use. Push to connect fittings suitable for 1/2 inch 1/4 inch 3/8 inch outer diameter air hose, such as air line blow gun kit, dust gun air pipe, and air line behind the seat of semi-truck. Also featuring DOT NPT connectors, a box contains push-in connectors of different sizes and materials.

【 CONVENIENT 】 Quick connect air hose fittings is convenient to install, maximum bending no air leakage, flexible 360 degrees free rotation, easy to disassemble.

【MATERIAL】High quality copper is used in the copper parts. The plastic part adopts high strength PBT, the maximum pressure is up to 35 kg. Release ring using POM material. Raw spring material is stainless steel 301, tempered treatment, service life up to one million times. Zinc jacket material for high quality zinc alloy! Stable performance and long service life.

【PLASTIC】 Air quick fittings maximum bending no air leakage, can withstand the maximum bending of the gas pipe, no obvious gap at the interface, no air leakage for daily use. PBT high grade injection molding plastic body, through the pressure resistant plastic body can bear ≈662kgf/cm² pressure resistance is not damaged. The density is as high as ≈1.5g/cm³.

【HIGHT DENSITY】Copper alloy has good mechanical properties, withstand cold, hot pressure strong force, durable wear resistance in complex environment, not easy to damage. The sealing property of the joint thread connection avoids the direct long-term friction of the thread. Rub and lead to gap expansion of air leakage, not easy to fall off and leak.

【ADVANTAGE】Circlip fatigue is the direct cause of affecting the life of the clamping force of the circlip, we push-to-connect fittings can be used repeatedly after clogging, high pressure resistance and stability. Ordinary after the ordinary joint trip, the clamping force of the spring is very weak, the pressure resistance is poor, and it can not be reused.
