The 50 Ohm impedance and TNC threaded interface make this a direct fit for systems where a BNC's bayonet lock is too loose under vibration — the threaded coupling holds the pair mated through the full 500-cycle rating without the intermittent opens a push-on interface can develop. ## Cable group — what fits the crimp The crimp ferrule and centre contact are sized for RG-174, RG-188A, RG-316, LMR-100, and M17/119-RG174. 500 mating cycles is the standard durability for a threaded RF connector — the gold-over-phosphor bronze centre contact resists fretting corrosion through repeated connects. In practice, the threaded coupling wears the plating on the outer thread more than the centre contact; if the nut starts to feel gritty before 500 cycles, the connector is still electrically sound but the interface torque should be checked against the manufacturer's spec.","metaTitle":"Amphenol RF 031-2318-RFX TNC Jack, 50 Ohm, Bulkhead, Crimp","metaDescription":"Amphenol RF 031-2318-RFX TNC jack, 50 Ohm, bulkhead front-side nut mount, crimp termination for RG-174/316/LMR-100.

These are all 50 Ohm flexible coax with a nominal 0.100-inch outer diameter. RG-58 and RG-142 require a larger ferrule — the 031-2367-RFX plug covers those cables."},{"question":"Does 031-2318-RFX include the mounting hardware?","answer":"Yes — the kit includes 7 pieces: the connector body, one centre contact, one ferrule, one gasket, one lockwasher, one nut, and one sleeve. No additional hardware is needed for a standard bulkhead installation."},{"question":"Is 031-2318-RFX compatible with RG-58 cable?","answer":"No, the crimp ferrule and centre contact are sized for RG-174/188/316-class cables, not RG-58.
