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.

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 bonding jumper ring assures positive ground between telescoping cyl
