Cable Fit and Termination — RG-174, 188, 316 Double Braid
The 413985-4: This plug is designed for RG-174, RG-188, and RG-316 double-braid cable groups. The contact terminates by crimp or solder; the shield crimps over the ferrule. The PTFE dielectric handles the temperature range and keeps impedance stable through the termination. If you're working with RG-316, this plug is a direct fit.
