JACO has been able to mold the sleeve as an integral part of the nut, eliminating the need for a two piece assembly. Although fittings were originally developed for copper tubing, other fittings were then later engineered with plastic grippers for plastic tubing. Today, JACO fittings are widely used with all types of tubing including copper, plastic, aluminum and glass. JACO Vibra-Pruf fittings typically cost less than metal fittings and they offer better resistance to corrosion and chemicals. Additionally, we offer four different plastic resins for a range of applications dealing with temperatures, acids and chemicals.
Metric sizes are also available.
Various resins are used, depending on the application. JACO plastic fittings are made of nylon, acetal copolymer, polypropylene, and polyvinylidene fluoride.
