JACO fittings are widely used with all types of tubing including copper, plastic, aluminum, stainless steel, and glass while offering four different plastic resins for a wide range of applications dealing with temperatures, acids, and chemicals.
Proper 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 due to the low density and softness of plastic
An inherently low resistance to flow, caused by smooth internal surface
A resistance to scale buildup
JACO fittings are available in size ranges from 1/8 in. through 7/8 in. 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.
The appropriate resin should be used depending on the application of the fitting. JACO produces plastic fittings in four different materials: polyvinylidene fluoride (PVDF), acetal copolymer, polypropylene and nylon.
How to identifying Jaco fitting materials:
PVDF is a semi translucent off white color, somewhat translucent.
Acetel Copolymer is a shiny white color, smooth slippery shiny white.
Polypropylene is a solid opaque white, flat white (most white of fittings).
Nylon is an off white almost a very light gray in color, (a little whiter than PVDF material but not as white as Celcon).
