Applications
• UNY and UNF unions are used for joining conduit and
connecting conduit to enclosures. Facilitates modifi cations,
permits removal of enclosures without turning or removal of
conduit.
• Expansion unions compensate for 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
— Concentric ring interlocked design of 1/2”, 3/4” and 1” sizes
makes possible smaller diameter, allowing use in tighter
spaces. 1-1/4” and larger UNY sizes have removable male
nipple.
• Expansion unions
— One-piece design eliminates need for disassembly during
installation.
— Telescoping cylinder within cylinder design permits
expansion or contraction.
— Standard or long types available.
— Small external diameters—excellent in restricted areas in
wiring of pumps, motors, and other equipment.
— Internal phosphor bronze “bonding jumper” ring assures
positive ground between telescoping cylinders.
