For use with UHF plugs.","salesMarkdown":"## UHF Reducing Adapter for Interface Conversion The Amphenol RF 83-168-RFX is a UHF reducing adapter, designed to step down between two different UHF connector sizes. It is a passive accessory — not a complete connector — that allows a larger UHF plug to mate with a smaller UHF jack or cable connector. The nickel-plated brass body provides the RF shielding and mechanical durability typical of the UHF series, which is a threaded-coupling interface common in low-frequency RF applications up to about 300 MHz. ## Construction and Compatibility Machined from brass with a nickel body finish, the 83-168-RFX resists corrosion and maintains a consistent ground path through the adapter shell. It is intended for use with UHF plugs — the threaded coupling of the UHF interface ensures a vibration-resistant mate once tightened. The silver color is standard for nickel-plated RF components and does not indicate a separate plating grade. ## Comparing the 83-168-RFX with the 83-185-RFX Both the 83-168-RFX and the 83-185-RFX are Amphenol RF UHF reducing adapters with the same nickel-plated brass construction and silver color. The difference is the adapter step — each one converts between a specific pair of UHF interface sizes. For a procurement decision, confirm which UHF plug and which target jack size your harness uses, then select the adapter that bridges that gap.","metaTitle":"Amphenol RF 83-168-RFX UHF Reducing Adapter, Nickel Brass","metaDescription":"Amphenol RF 83-168-RFX UHF reducing adapter, nickel-plated brass body.
