Appleton UNY UNF and UNL explosionproof and dust-ignitionproof unions are used for joining conduit and connecting conduit to enclosures. They facilitate modifications and permit the removal of enclosures without turning or removing conduit. They are also available as expansion unions which compensate for the expansion and contraction of conduit.
Features
Explosionproof dust-ignitionproof Smooth rounded integral bushing in each hub protects conductor insulation Accurately tapped tapered threads for tight rigid joints and ground continuity Non-expansion unions are concretetight. The concentric ring interlocked design of the 1/2in 3/4in and 1in sizes makes possible smaller diameter allowing use in tighter spaces. 1-1/4in and larger UNY?sizes have a removable male nipple Expansion unions are a one-piece design that eliminates the need for disassembly during installation. The telescoping cylinder within cylinder design permits expansion or contraction. Both standard or long types are available The small external diameter of the expansion unions makes them ideal for use in restricted areas such as the wiring of pumps motors and other equipment. The internal phosphor bronze inbonding jumperin ring assures positive ground between telescoping cyl
