3/8" DOT/PTC – ½" NPT Straight

Big port. Small line. One fitting between them. Tanks and compressors do not all speak 3/8 inch. A half inch NPT bung on a tank needs an adapter that steps it down to the push-to-connect line the rest of the system runs; and it needs to do it without a stack of bushings that leak at every joint. This is that adapter in one piece: 1/2 inch NPT male on the port side; 3/8 inch DOT push-to-connect on the line side. One thread to seal instead of three. One place to chase if it ever weeps. Read the title rather than the description on this one - the body copy on this listing was written for the 3/8 inch NPT version. The part you are buying is the 1/2 inch.

  • Half inch port to 3/8 inch line in one step - no bushing stack and no extra joints to seal.
  • Push-to-connect line side - the tube pulls for service without cutting.
  • Largest thread in the range - the fitting for a big tank bung or a compressor outlet.
  • Kit-matched part - the same straight Accuair supplies inside its systems.
  • Thirteen dollars - worth having spare rather than stalling an install over a fitting.
