M sub-miniature tube fittings are available for applications where space is more of a concern than flow rate. The tubing features a tight minimum bend radius of just 4 mm. The economical tubing is available in 20 m rolls of your choice of seven available standard colors. Four fitting types are available in two connect the tubing to a straight or angled M3 or M5 threaded port, and two connect the tubing to larger tubing or plug into a standard KQ2 Series one-touch fitting.

KQ2 one-touch, metric and inch size fittings are available in a wide variety of sizes, body styles and thread types. The specially designed packing provides positive sealing under pressure without the reduced flow common with compression fittings. The KQ2 release collar releases both the chuck and collet to provide a low disconnection force for easy removal of the tubing. KQ2 fittings are available to order in multiples of 10.
