BRASS REDUCER COUPLING 3/8 X 1/8

This brass reducer coupling joins a 3/8in NPT female pipe end to a 1/8in NPT female pipe end, letting you connect two pipes or fittings of different sizes directly in line without extra adapters.

Machined from solid brass for corrosion resistance, it's commonly used on air brake, fuel, and pneumatic accessory lines across Kenworth, Peterbilt, Freightliner, International, Mack, and Volvo trucks. United Truck Parts stocks this coupling at our Pennsylvania warehouse for fast shipping across the I-78 corridor — call us for fitment questions or bulk pricing.
