One-Touch Couplings (Other Shapes: PT Jacks)
Quick connect fittings are couplings used when connecting tubes used as pneumatic equipment lines. They can be fastened just by inserting them into a tube of compatible size, and can be easily removed by pressing in a ring on the fitting opening. Quick connect fittings come in a number of different varieties. Examples include straight (having a male screw thread at the side connecting to the tube), female straight (having a female screw thread), elbow (having a male screw thread tilted at a 90-degree angle), union (having a tube fitting mechanism on both ends designed to connect 2 tubes together) and tee (having the outlets to the tubes branched into a T shape). Screw threads are made of different materials for different applications. There are quick-connect fittings that can be used for applications such as clean environments, food/chemicals, static electricity dispersal/charge prevention and powder spattering.
