Parker Hannifin Corporation’s Fluid System Connectors Division introduces its black TrueSeal fittings, which offer the same leak-free benefits and ease of assembly as the rest of the TrueSeal line. Widely used in water conditioning, filtration and RO applications, as well as on dispensing systems. TrueSeal fittings feature an all-plastic body design that offers reduced weight and eliminates rust, corrosion and system contamination that can be associated with metal fittings. These fittings are available in ANSI/NSF 51- and/or NSF/ANSI 61-compliant materials. The collets are offered in either a patented, all-plastic design for use with flexible tubing or with a metal grip edge made from 300-series stainless steel for use on all tubing, including copper. A removable collet design permits O-ring replacement in the field. Collets are available in colors for easy color-coding of systems.
