The kit ships as four pieces: the connector body, a crimp contact, a ferrule, and an insulator. ## Cable Compatibility — Which Coax Fits This plug is specced for RG-174, RG-188, RG-188A, RG-316, LMR-100, and M17/119-RG174 — all thin-jacket cables with a nominal dielectric diameter around 0.100 inch. The crimp ferrule and centre contact are sized for that cable group; the plug will not crimp properly on RG-58 or RG-213, which have a thicker dielectric. For RG-58 cable, the sibling 31-320-RFX uses the same BNC plug body but with a larger ferrule and contact set. No last-time-buy or end-of-life notice has been issued.","metaTitle":"Amphenol RF 31-315-RFX BNC Plug, 50 Ohm, 4 GHz","metaDescription":"Amphenol RF 31-315-RFX BNC plug, male pin, 50 Ohm, 4 GHz max, crimp termination for RG-174/188/316 coax.
