  •     1/2-28 x 3/4 NPT Thread Adapter

** This is no Ordinary 3/4" NPT Thread Adapter **

  • Adapter is Gun Barrel Flat Black (MagPhosphate finish)
  • Solid Steel and CNC'd to perfection (no aluminum galling here)
  • Female threading fits all 1/2-28 threaded barrels (.223, 5.56, 9MM, etc)
  • Male outside threading fits all 3/4 NPT Accessories (example: WIX-24003 and NAPA 4003
  • MagPhosphate finish (just like your barrel or BCG) exceeds all MIL-SPECS for other's Black-Oxide finishes

  • The 3/4" NPT is a tapered design of the 1"-14 SAE bolt thread pattern. They are similar with the exception of this taper.
  • We've modified our 3/4" NPT so it remains within the specs of both the 3/4" NPT and 1"-14 SAE style threads.
  • THIS modification prevents the adapter from cutting into the threads of the female filter (or auxiliary device) as standard 3/4" NPT adapters are designed to do. The threads on a standard fully tapered unmodified 3/4" NPT are larger than the female threads. The ridges are designed to cut into the valley's of the female threads - it's how they tighten and seal. Our modified thread adapter remains within the specs of the 3/4" NPT female and will NOT damage or cut into the filter housing or its threads.
  • Our 3/4" NPT thread permits no wiggle tightening to the backstop (shoulder) acting the same as a nut and bolt preventing Leakage and unwanted Movement (Wiggling). Standard 3/4" NPT devices tighten mid thread preventing symmetry and device security.
  • BONUS - Our 3/4" NPT thread permits all 1"-14 SAE threaded devices to be used providing for more auxiliary options
  • You will not notice a taper but you will notice better fitting and a more secure device attachment!!!

  • Oil as you do your barrel. WD-40 works great as do all gun oils. MagPhosphate crystals store the oils and provides a long lasting barrier against rust

What's Included:
  • (1) 1/2-28 x 3/4" NPT MagPhosphate Barrel Thread Adapter
