Crouse-Hinds UNY Male Conduit Union

The Crouse-Hinds UNY conduit union joins two lengths of threaded rigid or IMC conduit, or connects conduit to an enclosure hub, without turning either run. Tighten the union nut and the joint is complete, which makes it the practical choice where conduit is already fixed in place or where equipment needs to come out for service. The union is offered in steel or in copper-free aluminum (SA catalog numbers) and is built for hazardous (classified) locations, so the joint keeps the explosionproof integrity of the conduit system.

Key Features

  • Male thread on one end, female on the other
  • Material: Steel, or copper-free aluminum on SA catalog numbers for corrosive areas.
  • Ground joint design: machined mating faces form a flame path that keeps the conduit system explosionproof once tightened.
  • Trade sizes: 1/2" through 2" NPT for threaded rigid steel and IMC conduit.
  • Service access: disconnect fixtures, enclosures or equipment without unthreading the conduit run.

Certifications & Compliance

  • Class I, Division 1 and 2, Groups C, D (1/2" through 1" sizes also Groups A, B)
  • Class II, Division 1, Groups E, F, G; Class II, Division 2, Groups F, G
  • Class III
  • NEC/CEC

Applications

  • Refineries, chemical and petrochemical plants
  • Paint spray booths and fuel handling areas
  • Grain elevators, flour and feed mills (dust locations)
  • Wastewater treatment and other classified industrial areas

Crouse-Hinds UNY205 SA – Frequently Asked Questions

1) Can I use a Crouse-Hinds UNY union in a Class I Division 1 area?
Yes. The UNY series male conduit union is rated Class I, Division 1, so it's approved where ignitable gas or vapor concentrations can be present during normal operation, not just under fault conditions. It also carries a Group B rating, which covers hydrogen and gases with similar ignition characteristics. That Group B rating is the part worth checking against your area classification drawing, because most conduit fittings stop at Groups C and D.
2) What is the difference between the UNY and UNY SA versions of the Crouse-Hinds male conduit union?
The SA suffix is copper-free aluminum. Both builds exist in every trade size, so a 3/4 inch opening can be filled with either the UNY205 or the UNY205 SA. Specify SA where your plant standard bans copper-bearing alloys, which is common in refineries, chemical process areas, and anywhere acetylene or ammonia service is a concern. If your spec doesn't call it out, the standard version is the one to order.
3) Will a Crouse-Hinds UNY union work with EMT or PVC conduit?
No. The UNY union is built for rigid metal conduit and IMC only. EMT uses compression or setscrew connectors and has no threads, and PVC is solvent welded, so neither will make up to this fitting. A Class I Division 1 run should be threaded rigid or IMC anyway, EMT is not permitted in Division 1 as a wiring method.
4) What trade sizes does the Crouse-Hinds UNY conduit union come in?
Six trade sizes: 1/2, 3/4, 1, 1-1/4, 1-1/2 and 2 inch, ordered as UNY105, UNY205, UNY305, UNY405, UNY505 and UNY605. Each size is available in both standard and copper-free aluminum (SA). Match the union to the conduit trade size you're joining, there's no reducing version in the range.
5) Why would I use a conduit union instead of just a coupling on a rigid conduit run?
A standard threaded coupling requires you to rotate one length of conduit to make it up, which is impossible once both ends are fixed to boxes, enclosures, or structure. A union like the UNY makes the joint without turning either conduit, so it's what you install at the point where two fixed runs meet, or where you need a serviceable break to pull an enclosure later. On this one the male threaded end mates to female conduit threads and maintains the electrical continuity path through the raceway.
6) Does the Crouse-Hinds UNY union meet NEC and Canadian Electrical Code requirements?
The UNY series is built to NEC and CEC standards, which matters for cross-border work and for facilities that spec to CEC. That's the standards reference the manufacturer states for the fitting, alongside the Class I Division 1, Group B rating.
7) Is the Crouse-Hinds UNY union suitable for a paint spray booth or fuel dispensing area?
Yes, both are named applications for the UNY union, along with chemical processing plants, refineries, aircraft hangars, pharmaceutical manufacturing, and grain handling. All of those are areas where a Class I Division 1 rated fitting is what the classification calls for. Confirm the gas group for your specific area, the UNY covers Group B, which is the most demanding of the Class I gas groups.
8) What does the aluminum extended handle on the Crouse-Hinds UNY union do?
It's the wrenching surface. The extended handle gives you leverage to tighten the joint by hand or with a wrench in tight spots, in a tray, against a wall, or overhead, where you can't get a pipe wrench onto a plain hex. The aluminum body also resists corrosion in wet process and outdoor areas.
