Five gray nylon 1/2" NPT liquid-tight strain relief connectors with rubber seals and locknuts

Arlington Industries Inc

Arlington Industries Inc Liquid Tight Strain Relief 1/2" NPT Gray Pack of 5

SKU CH-BYFG-1GA8M

A five-pack of 1/2" NPT gray liquid-tight strain-relief connectors with a single round hole for #10 or #12 USE wire (.100–.300") and Buna-N seals for waterproof, direct-burial use

  • Waterproof cable entry with 1/2" NPT threads for outdoor enclosures
  • Chemical-resistant nylon body with Buna-N seals withstands salt water and oils
  • Single-hole design accepts one #10 or #12 USE-2 conductor per connector
  • UL Listed for NEMA 4, 4X and 6 ratings in direct-burial installations
  • Pack of five includes rubber washers and locknuts for immediate installation

Connector Type & Thread Size

These Arlington liquid-tight strain-relief connectors feature a 1/2 inch NPT thread and a single round hole. They accept one #10 or #12 USE-2 conductor with an insulation diameter between .100 and .300 inch. The nylon body and Buna-N seal resist salt water, weak acids, alkalis, alcohol, and many oils.

Critical Wire-Range Match

The opening narrows as the nut is tightened, compressing the rubber seal around the wire. Verify that each conductor falls within the .100 to .300 inch range before purchase; cables outside this window will not seal properly and the fitting will not meet its UL listing.

Installation Notes

Each pack includes five connectors with rubber washers and locknuts for a complete assembly. Thread the connector into a 1/2 inch NPT knockout, insert the wire, and tighten the nut to compress the seal. The non-corrosive nylon construction allows direct burial, but over-tightening can damage threads or split the rubber washer.

Questions about this item

What does the 0.100 to 0.300 inch wire opening mean when I am running cable through it?

The opening accepts one #10 or #12 USE-2 conductor; as you tighten the nut the rubber seal compresses around the wire to create a watertight grip.

What does the 1/2 inch NPT thread limit in a real installation?

The 1/2 inch NPT thread fits standard 1/2 inch knockout holes in junction boxes and PV combiner enclosures, capping the connector to that opening size.

What clearance do I need behind the box to mount this strain relief?

You need enough depth for the connector body, the rubber washer and the locknut to seat fully against the enclosure wall.
