Helpful Ways of Finding the Best Stainless-Steel Pipe Fittings Suppliers
February 6, 2018What You Should Know About Push to Connect Air Fittings?
March 20, 2020The rapid screw or push-on fittings have multiple applications in the pneumatic industries. They help in making the right connection between a water supply valve and soft tubing. They ensure a simple insertion of tubing into the fitting for making secure connections. These valves can be used manually without any special tools. They ensure a tight grip with a steady and secure connection.
The Basics of Their Build:
The rapid screw fittings are designed with three main components, viz. a flexible collet, a fitting body, and an O-ring. The body is made of polypropylene or Acetal having a precise geometry to house the collet, tubing, and O-ring at the time of assembly. They are available in different configurations like elbows, tees, threaded, and union connectors. The plastic collet of push on valves is designed stainless steel gripping teeth that are moulded into its legs. It provides a firm grip on the copper or plastic tube. The collet legs are flexible to allow easy connection and disconnection of the tubing. The O-ring of these fittings is made from food-grade rubber compounds like EPDM or Nitrile. It remains seated inside the fitting body to form a seal on the outer diameter of a tube.
The Installation of Push Fittings:
When making the connections with push on fittings, the tubing is cut square and cleaned properly to be free from burrs, sharp edges, and score marks. This tube is inserted through the collet past the O-ring to the end of a tube. Push it as far as it can go. The O-ring will seal it on the outer diameter. Similarly, it can be easily disconnected by pushing the collet against the fitting.
The Applications of Push Fittings:
These fittings are designed as a component of various industrial processes. It can be used for pneumatic control systems and for air supply flow in the advanced pneumatic machines. Also, they are used for precision parts used in the automatic devices.
The Features of Push Fittings:
When looking to buy push fittings for your specific requirements, you must check the features integrated into their design to offer accuracy in the processes. The pressure ratings of these fittings should be 290 psi at CWP while their temperature ratings can be measured up to 160 degrees Celsius. Check the leak-proof seal system of the push fittings to ensure reliability and performance.
They should be manufactured with SS316 materials. The fittings made by a reputed company can withstand any level of purge without any drop in pressure. It should have proper testing facilities to check the quality of fittings.
The availability of a variety of designs makes them ideal for use in many industries and commercial installations. You must check their features and specifications clearly when buying them.
