Single-Pole Protective Cap

The Hubbell HBL15FCAPW is a white thermoplastic elastomer cap designed to seal female single-pole connectors. It carries NEMA 12, 3R and 4X enclosure ratings for indoor and outdoor use. Electrical contractors and maintenance teams use it to protect 150 A rated contacts on Series 15 devices from moisture and debris.

Replaces lost or damaged caps

This cap fits Series 15 connectors rated at 150 A, restoring the NEMA 12, 3R and 4X seal when the original cover is missing or cracked. The upgrade is worth it whenever an exposed female connector risks water ingress or contamination in wash-down or outdoor environments. It does not serve connectors outside the Series 15 range or devices with different current ratings.

Simple press-on installation

The cap presses onto the female connector by hand; no tools are required for a secure fit. The 2.25 in length and 0.8 in width match the Series 15 profile so the seal engages fully. Problems arise if the cap is forced onto a non-Series 15 device or if the connector face is already deformed, preventing the NEMA-rated seal from forming.
