Liquid-tight cord connector

This straight nylon connector provides a liquid-tight seal and strain relief for flexible cord and cable. It accepts cord diameters from .50 to .63 inches and fits a 3/4 inch male NPT thread. The fitting can be tightened with a screwdriver or pliers when space is limited. Suitable for wet or dry locations.

Nylon construction benefits

The nylon body resists corrosion and many common chemicals found in automotive and industrial environments. Its non-metallic design eliminates the risk of conductivity between the connector and the enclosure. The material also reduces weight compared to metal alternatives while maintaining mechanical strength.

Installers needing liquid-tight strain relief

Electricians and maintenance technicians terminating flexible cord in junction boxes or equipment enclosures will find this connector appropriate. Buyers who require a metallic connector for grounding continuity or high-temperature applications should look at something else. Those needing a larger cord diameter range or a different thread size will also need a different fitting.

Questions about this item

Will the nylon body or sealing gasket need periodic replacement?

The connector is moulded from nylon with an integral liquid-tight seal; no separate gasket or user-replaceable parts are specified.

What is the maximum cable diameter the 0.50–0.63 in range can reliably grip?

The connector accepts flexible cord from .50 in up to .63 in outer diameter; cables outside this range will not seal properly.

Does the nylon housing soften or deform when the connector runs warm in a sealed enclosure all day?

Nylon construction is rated for use in wet or dry locations; no temperature derating or deformation limit is provided in the specifications.
