This kit is compatible with the RG-59, 62, 140, 210, and Belden 8241, 8263, 8279, 9209 cables. The crimp ferrule and centre contact are sized for the dielectric and braid diameters of those cables. ## Bulkhead Install — Front-Side Nut, No Backside Access Needed The mounting feature is bulkhead with a front-side nut — you drop the jack through the panel from the front and tighten the nut from the same side. That matters when the back of the panel is a rats-nest of cables or a sealed enclosure you don't want to open. The kit includes the gasket for a weather-resistant seal against the panel face; the lockwasher keeps the nut from backing off under vibration.","metaTitle":"Amphenol RF 31-343-RFX BNC Jack, 50 Ohm, 4 GHz, Bulkhead Kit","metaDescription":"Amphenol RF 31-343-RFX BNC jack, 50 Ohm, 4 GHz max, 500 mating cycles. 7-piece bulkhead kit for RG-59/62/Belden 8241.
