  • 3/8" NPT MALE × 1/4" NPT MALE THREADS – Features standard National Pipe Taper (NPT) male threads on both ends (MNPT to MNPT), designed to connect female pipe fittings of different diameters or extend pipe length. Compatible with most air tools, hoses, and NPT-threaded systems used in plumbing, compressed air, hydraulics, refrigeration, instrumentation, and gas lines.
  • ACTUAL FITTING SIZE: 5/8" OD × 1/2" OD – Although the thread sizes are 3/8" NPT and 1/4" NPT, the actual outer diameters measure approximately 5/8" and 1/2", respectively. NPT thread sizes are nominal and do not represent actual measurements. These threads have a 60° taper and typically do not screw completely flush. Please refer to the size chart and verify dimensions before purchase.
  • FUNCTION & APPLICATION – Designed to connect female pipes of different diameters or extend pipe length. Ideal for a wide range of applications, including residential plumbing, commercial air compressors, hydraulic systems, instrumentation setups, gas piping, and HVAC or refrigeration equipment. The hex nipple design allows for easy tightening and loosening with a standard wrench.
  • PREMIUM BRASS CONSTRUCTION – Constructed from thick, solid brass for excellent corrosion resistance, strength, and longevity. Features deep, precise threads, low magnetic permeability, and high temperature ductility. Suitable for demanding environments and frequent use.
  • VALUE 2-PACK WITH 300 PSI RATING – Includes 2 pieces of 3/8" NPT male × 1/4" NPT male brass reducing hex nipples. Each adapter is rated for up to 300 PSI working pressure, ensuring secure performance in both light-duty and heavy-duty systems.
