The kit includes the plug body, a gold-plated brass centre pin, a crimp ferrule, and a PTFE dielectric sleeve, all in one order code. The threaded coupling (not bayonet) gives a positive mechanical lock — the TNC interface is essentially a threaded version of the BNC, offering better vibration resistance and a higher frequency ceiling. This kit is dimensioned for RG-174, RG-188, RG-188A, RG-316, LMR-100, and M17/119-RG174 — all roughly 0.110-inch-diameter coax with a solid or stranded centre conductor. The crimp-style shield termination and contact termination mean you need a crimp tool with the correct hex die for the ferrule and centre pin.","metaTitle":"Amphenol RF 031-2315 TNC Plug Kit, 50 Ohm, RG-174/316","metaDescription":"Amphenol RF 031-2315 TNC plug kit, 50 Ohm impedance, for RG-174/188/316/LMR-100 cable.

This is the standard impedance for most RF test, telecom, and antenna systems — match it with 50 Ohm cable and 50 Ohm TNC jacks to avoid return-loss penalties."},{"question":"What cable does the 031-2315 fit?","answer":"The kit is designed for RG-174, RG-188, RG-188A, RG-316, LMR-100, and M17/119-RG174 cables. These are all approximately 0.110-inch-diameter coax with a 50 Ohm characteristic impedance."},{"question":"Does the 031-2315 connector kit include all necessary parts?","answer":"Yes — the kit contains four pieces: one TNC plug body, one centre contact (gold-plated brass pin), one crimp ferrule, and one PTFE dielectric sleeve. You will still need the correct crimp tool for the centre pin and shield ferrule."},{"question":"Is the 031-2315 connector threaded or bayonet?","answer":"Threaded. The TNC interface uses a threaded coupling nut, not a bayonet lock.
