| For Connecting Conduit To Conduit |
| Explosionproof, dust-ignitionproof; Smooth, rounded integral bushing in each hub protects conductor insulation; Accurately tapped, tapered threads for tight, rigid joints and ground continuity; Concentric ring interlocked design sizes makes possible smaller diameter, allowing use in tighter spaces; UNF unions are used for joining conduit and connecting conduit to enclosures, Facilitates modifications, permits removal of enclosures without turning or removal of conduit |
| Smooth, rounded integral bushing in each hub to protect conductor insulation |
| Accurately tapped, tapered NPT threads for tight, rigid joints and ground continuity |
| Concentric ring interlocked design sizes makes possible smaller diameter, allowing use in tighter spaces |
| Facilitates modifications, permits removal of enclosures without turning or removal of conduit |
| Female threaded coneection |
| Chromate/epoxy powder coated/zinc electroplated finish |
| Triple-coated (Zinc electroplated/chromate/epoxy powder coated) |
| 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 |
| 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 cylinders |
