A one touch fitting is a fitting that allows one-touch removal of gas, air, and water tubing. A one touch fitting makes it easy to connect piping and tubing for gas, air, and water. To use, simply insert the tube and connect the piping with a screw. The fitting is secured with a click so you can check to make sure it is properly fitted. The connection to the piping can be either male or female thread.
The shape of the fitting includes elbow type, union type, and branched type, etc., and can be selected according to the intended use.
One touch fittings are used in a wide range of applications to connect air and water piping for machinery and equipment in a wide range of fields, such as food, medicine, medical care, and semiconductors. One touch fittings come in a variety of shapes and sizes, including those that connect pipes to tubes and those that connect tubes to tubes. A one touch fitting makes it easy to convert tube diameters.
Recently, fittings have become lighter and more compact, and they can be used in smaller spaces.
The mechanism of the one touch fittings is simple. When the tube is inserted all the way into the fitting, the inner back ring and lock ring bite into the tube and snap it into place. The fitting is then sealed with a sealant to prevent leakage. When the open sleeve made of resin is pushed in, the lock ring loosens and the tube can be pulled out.
The threaded part of most one touch fittings is made of stainless steel. Some products use corrosion-resistant SUS304, while others use brass with electroless nickel plating to prevent rusting. Resins such as polypropylene and polybutylene terephthalate are used for the ring portion. Nitrile butadiene rubber is often used as the sealing material, but fluorine rubber is used for products with high chemical resistance. Products with high heat resistance, flame resistance, and chemical resistance are available. One touch fittings made of resins are also available.
Air, water, and gases are used as fluids that flow through one touch fittings. When water or other liquids are used, an insert ring is inserted into the tube. The operating temperature is about 32°F to 140°F. It is not designed to withstand freezing.
