Liquid-Tight Cord Connector

The Hubbell SEC38BA is a liquid-tight cord connector built to seal a single cable where it enters a 3/8 in NPT threaded enclosure. Its black nylon body resists corrosion and provides insulated protection for indoor or outdoor wiring runs. The straight style keeps the cable path short and direct. UL 514B and CSA C22.2 No. 18 listings confirm code-compliant installation.

Installers Sealing Small-Diameter Cables

This connector suits electricians and maintenance crews who need to seal cords from 0.18 in to 0.31 in outside diameter in junction boxes or control cabinets. It is not for armoured cable, multi-conductor bundles or applications that require external strain-relief glands. Buyers needing larger cord ranges or right-angle entry should select a different fitting.

3/8 in MNPT Box Connection

The defining specification is the 3/8 in male NPT thread that mates with the enclosure knockout. Only cords within the 0.18 in to 0.31 in diameter range will seal correctly in the nylon gland. Match both the thread size and the cord diameter before ordering.
