Product details

It is a 7-piece kit that includes the connector body, contact, ferrule, gasket, lockwasher, nut, and sleeve — everything needed for a single cable termination.

It accepts RG-179, 179A, 179B, 187, and 187A cable groups — the crimp shield termination and crimp contact termination match the standard field-termination workflow for these small-diameter coax cables.

Mounting and Hardware

The bulkhead front-side nut mounting style means the jack installs from the outside of the panel — the gasket and lockwasher seal the opening and prevent rotation. The kit includes the nut and lockwasher, so no separate hardware order is needed for a single-port install.
