Liquid-tight cord connector for 1/2 in NPT entry

This Hubbell SEC50BA connector seals a single cable where it enters a 1/2 inch NPT threaded opening. The nylon body accepts cord diameters from 0.17 in to 0.45 in and provides an insulated, straight-through connection. It is suited for installers who need a compact, low-profile gland for indoor or outdoor junction boxes. The black finish matches standard enclosures and the unit meets CSA C22.2 No. 18, UL 514B and VDE requirements.

Replaces open knockouts

The connector upgrades a plain threaded hole into a sealed, strain-relieved entry point without adding external relief hardware. The jump is worth it when the installation must meet liquid-tight standards and the cable falls within the 0.17 in to 0.45 in range. It is not for cables thicker than 0.45 in, for multi-cable entries, or for applications that require a separate external strain-relief device.

Limited to 1/2 in NPT threads

The NPT interface restricts use to enclosures tapped for 1/2 in NPT; metric or PG threads will not engage. The sealing gland only accommodates one cable between 0.17 in and 0.45 in, so larger conductors or bundles need a different fitting. No external strain relief is fitted, so the connector relies on the gland compression alone for cable retention.

Questions about this item

What is the 1/2 in MNPT box connection size for this Hubbell SEC50BA cord connector?

The connector mounts to a 1/2 in MNPT threaded opening, with an overall length of 1 11/16 in from box to end, and accepts cord diameters from 0.17 in to 0.45 in.

How do you install the Hubbell SEC50BA liquid-tight connector, and what step is often missed?

Thread the nylon body into the 1/2 in MNPT opening, insert the cord through the gland, then tighten the compression nut to seal the 0.17 in to 0.45 in range; the step often missed is fully tightening the nut to engage the liquid-tight seal.

When should the nylon gland be replaced on this SEC50BA connector?

Replace the gland if the nylon body shows cracking, the compression threads strip, or the seal no longer grips cords within the 0.17 in to 0.45 in diameter range.
