SOLID BRASS CONSTRUCTION MATERIAL :made of nickel-plated brass for durability and corrosion resistance. which ensures longevity and resistance to the effects of compressed air and environmental factors,DOUBLE O-RING COMPRESSION SEALING : ensures 100% sealing in high working pressure. Max working pressure: 300 PSI. Connect with no glue, soldering or crimping, dismantle is also easy, just unscrew the sleeve and unplug the tubing.,AN ESSENTIAL 3/4" ELBOW FITTINGS: In the context of compressed air systems, such fittings are crucial for routing tubing around corners or obstacles while ensuring proper airflow. By using elbow fittings, you can create a more flexible and adaptable layout for your compressed air system, optimizing space and efficiency in the workshop or garage.,EASE OF INSTALLATION : Bevel the inside of the tubing by inserting the reaming tool and rotating it. Remove nuts and split ring from fittings and place on tubing; Push the fitting onto the tubing and fully against the shoulder of the fitting; Turn the nut finger tight. Put a reference mark on the nut and fitting body; Tighten nut with wrench a minimum of 3/4 of a turn or until tight.,VERSATILE USAGE : Our Equal Elbow Fitting has various applications within compressed air systems, particularly in workshop or garage settings. Some common applications include:Pneumatic Tools,Air Line Distribution,Air Filtration Systems,Air Suspension Systems,Painting Equipment,Air Dryers and Filters,Material Handling Systems,Air Brake Systems etc.
