Conduit Straight Union 1 1/2in Iron

This Appleton Century Crofts straight union connects two rigid conduit runs of 1 1/2in trade size. The iron body carries a chromate, powder-coat and electroplate finish for corrosion resistance. It suits vertical or horizontal installations in hazardous-location wiring systems.

Female FNPT ends thread onto conduit

Both ends are 1 1/2in FNPT so the fitting threads directly onto male conduit threads without adapters. The 2 3/16in overall length fits tight enclosures. Cross-threading is the typical issue; start threads by hand and use a strap wrench on the flats to avoid damaging the coating.

Verify conduit trade size and thread standard

Confirm the existing conduit is 1 1/2in trade size rigid with male NPT threads before ordering. The fitting is restricted from sale in certain states; check local regulations for hazardous-area approval. No other conduit types or thread forms are compatible.

Questions about this item

How do I confirm the straight union is sealing properly after installation?

Check that both 1 1/2 in FNPT ends thread fully into the rigid conduit with no visible gaps and that the chromate and powder-coated iron surfaces sit flush at the 2 3/16 in overall length.

What comes in the box and what must I source separately?

The package contains the silver-finished iron straight union fitting only; compatible 1 1/2 in vertical or horizontal rigid conduit and thread sealant are not included.

Which trade-size version matches a 1 1/2 in rigid conduit run?

Choose the UNF150NR model with trade size 1 1/2 in and female-to-female FNPT ends, designed specifically for 1 1/2 in rigid conduit in vertical or horizontal orientation.
