SKU CH-ZHAR-MS1SK

Threaded aluminum nipple joins 1-1/4 inch IMC conduit in hazardous locations

  • Product typeCable Management & Conduit
  • Threaded male ends join IMC conduit securely
  • Aluminum construction resists corrosion in harsh environments
  • Hazardous-location rated for Class I, II and III divisions
  • Compact 1-5/8 in length fits tight spaces
  • Lightweight at 0.05 lb eases installation

Electrical Conduit Nipple

This 1-1/4 inch IMC nipple connects two threaded conduit sections in hazardous-location wiring systems. The aluminum body carries Class I Division 1 and 2, Groups A through D, plus Class II and III ratings for explosive atmospheres.

Sustained Load Performance

The plain aluminum finish resists corrosion during long-term exposure in industrial environments. Male NPT threads on both ends maintain a secure mechanical bond when conduit runs are subjected to vibration or thermal cycling.

Critical Specification

The 1 5/8 inch overall length determines whether the nipple fits between existing fittings in a tight enclosure. Buyers who need a longer or shorter spacer cannot use this part.

Questions about this item

Does the 1 5/8 in aluminum nipple generate heat or noise when conduit runs continuously?

The aluminum nipple is a passive fitting with no moving parts or electrical load, so it produces no heat or noise regardless of how long the conduit system operates.

What conduit and threading must already be in place for this 1 1/4 in MNPT nipple to install?

You need 1 1/4 in IMC or threaded RMC conduit with matching 1 1/4 in male NPT threads on both ends to thread the nipple between them.

Will the Class I Division 1 rating on this aluminum nipple stay valid when paired with older steel IMC conduit?

Yes, the nipple is listed for use with IMC and threaded conduit, so connecting it to existing steel IMC does not change its hazardous-location rating.
