BRASS REDUCING NIPPLE 1/2 X 3/8

This brass reducing nipple has male NPT pipe threads on both ends — 1/2in on one end and 3/8in on the other — letting you join two female-threaded fittings or ports of different sizes without an extra coupling.

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