JACO fittings are widely used with all types of tubing including copper, plastic, aluminum, stainless steel, and glass. JACO compression fittings are typically less expensive 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. JACO plastic fittings provide the following additional advantages:

• Exceptional 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.

• An inherently low resistance to flow, due to smooth internal

• A resistance to scale buildup.

JACO fittings are available in size ranges from 1/8″ through 7/8″ tube O.D. in most common figurations, such as: union, bulkhead, male and female connectors, male branch and male run tees, tee unions, and ferrule nuts. Metric sizes are also available on a special order basis. (Contact JACO for available metric sizes).

Various resins are used, depending on the application. JACO produces plastic fittings in four different materials: nylon, acetal copolymer, polypropylene, or polyvinylidene fluoride. (PVDF). The fittings can be manufactured in the resins natural color or in black pigment.
