Straight Union Push-In Fitting

The straight union is a two-port push-in fitting with a straight body. It is made of stainless steel, offering corrosion resistance and durability. The fitting uses a push-in mechanism: the tube is inserted into the collet, which grips it and creates a seal. To release, a simple push on the collet collar frees the tube. This allows for quick assembly and disassembly without tools. Typical construction includes a stainless steel body, a collet with stainless steel teeth, and an O-ring seal. The fitting is used in pneumatic circuits, water lines, and other fluid systems where a reliable connection is needed. It is suitable for tube sizes from 4 mm to 16 mm.
