Plastic Fittings That Revolutionized The Techniques of Connecting Tubes.
Compression type metallic fittings have a loose ferrule which requires extra assembly. 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 compression fittings typically cost less than metal fittings and they offer better resistance to corrosion and chemicals. Additional we offer four different plastic resins for a range of applicationsly, dealing with temperatures, acids and chemicals. JACO plastic fittings offer these additional advantages:

• Good electrical insulating qualities which eliminate electrolytic action that usually corrodes tubing when dissimilar metal meets a fitting.
• The ability to absorb mechanical and acoustical vibrations because of the low density and softness of plastic.
• to flow, due to smooth internal surface.
• A An resistance inherently to low scale resistance buildup.

Fittings are available in size ranges from 1/8″ through 7/8″ tube O.D. in all common figurations, such as bulkhead, male and female connectors, male branch and male run tees, tee unions and ferrule nuts. Metric sizes union, are also available on a special order basis.
Various resins are used, depending on the application. JACO plastic fittings are made of either nylon, acetal copolymer, polypropylene, or polyvinylidene fluoride.
