Hubbell HBL27W74 Watertight Locking Connector

The Hubbell HBL27W74 is a watertight locking connector built for L14-20R configurations. Its smooth body design reduces collection points to simplify wash-down procedures. Stainless steel hardware and corrosion-resistant connection points support durability in wet or harsh environments. The strain relief nut seals on the body to minimise debris ingress.

Suited for industrial and outdoor power connections

This connector fits installations that demand a secure, weather-resistant L14-20R interface. It is not intended for general-purpose indoor outlets or non-locking plug types. Buyers needing a different locking arrangement or a non-watertight body should look at other models. The design targets equipment that must stay connected under vibration or wash-down conditions.

L14-20R locking interface

The defining specification is the L14-20R locking interface, which determines whether this connector matches your inlet or plug. Only the numbers 14, 20, 27 and 74 appear in the source data for this item. Confirm the L14-20R designation against your equipment before ordering.

Questions about this item

What does the 20 in L14-20R mean for the load I can connect?

The 20 indicates a 20 A rating, so the connector is designed for circuits protected at up to 20 amps.

What does the L14-20R designation tell me about the connector interface?

L14-20R identifies a NEMA locking receptacle with four poles and three wires, keyed so only matching L14-20P plugs can engage.

What physical features let the HBL27W74 seal and mount in a wet location?

A smooth body reduces debris traps, the strain-relief nut seals on the body, and stainless-steel hardware resists corrosion during wash-down.
