It's built around a brass body with a nickel finish, which gives it the conductivity and corrosion resistance you'd expect from a field-grade RF adapter. The adapter is intended for use with standard UHF plugs, so if your rig runs on UHF connectors (PL-259 style), this part fits right into that thread pattern. ## Construction and Finish Brass body with a full nickel plating — the nickel provides a hard, corrosion-resistant surface that holds up to repeated mating cycles in a field environment. The silver color is the natural appearance of the nickel finish. It ships in bulk packaging, which is typical for adapter hardware that gets kitted into a maintenance stock or a harness build. The 83-185-RFX and the 83-168-RFX are both UHF reducing adapters from Amphenol, sharing the same brass/nickel construction and bulk packaging. The difference is in the base product number — 83-185 vs 83-168 — which typically indicates a different step size (e.g., adapting between different UHF thread diameters). If you're cross-referencing a BOM line, check which adapter size your assembly actually needs; the 83-168 won't mate the same step as the 83-185.","metaTitle":"Amphenol 83-185-RFX UHF Reducing Adapter, Nickel/Brass, Bulk","metaDescription":"Amphenol 83-185-RFX UHF reducing adapter.
