Product details

The 31-342-RFX: This connector is built for RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907 cables. Both the shield and center contact use crimp termination, which gives a consistent, repeatable mechanical and electrical bond—no solder wicking into the dielectric.

What the Kit Includes for a Bulkhead Install

The front-side nut mounting means the connector installs from the outside of the panel—the gasket seals against the panel face, and the lockwasher prevents the nut from backing off under vibration. No need to order hardware separately; it's all in the bag.
