Stainless steel tube-to-tube push-to-connect fittings are used for joining pneumatic tubes without a threaded machine port. This page includes union, tee, Y, bulkhead and reducing styles for 304/316 stainless steel air-line connections.
Some pneumatic lines need to join tube to tube instead of connecting to a threaded port. In wet, washed, outdoor or corrosive working areas, stainless steel fittings can be a better choice than standard plated fittings.
This page covers stainless steel tube-to-tube push-to-connect fittings, including ZKQG2U, ZKQG2T, ZKQG2E, G2U, G2H and G2T styles. These fittings are used when an air line needs to branch, pass through a panel, continue straight, or change from one tube size to another.
The push-in tube ports allow the tube to be installed by hand. Cut the tube end square, keep the outside surface clean, and push the tube fully into the fitting. After the line is pressurized, check each connection point for leakage.
Different body shapes are used for different layouts. A T fitting is used when one line needs to split from a straight tube run. A Y fitting gives a smoother branch direction in some compact layouts. A bulkhead style can help a tube connection pass through a panel or mounting plate. Reducing unions are used when two tube sizes need to be connected in the same air line.
Before ordering, confirm the tube outside diameter and fitting shape. For reducing styles, both tube sizes should be checked, because each side may have a different outside diameter.
