3/8" DOT/PTC - 1/8" NPT Straight Fitting

Eighth inch thread. Three eighths line. The 1/8 inch NPT port is the small one - the sensor boss; the gauge tap; the spare hole in a manifold end cap. It is also the easiest thread in the whole system to strip. This straight takes that port up to a 3/8 inch DOT push-to-connect tube in a single body. No bushing stacked under a fitting; one tapered thread to seal and one tube to push home. It is the same fitting Accuair supplies inside its own systems. A cracked collet or a rounded hex on install day costs eleven dollars rather than a week of waiting. Seal the NPT side. Leave the push-to-connect end dry.

  • Small port to full line - a 1/8 inch NPT boss feeding 3/8 inch tube in one body.
  • No bushing stack - one tapered thread to seal instead of two joints to chase.
  • Push-to-connect line side - the tube pulls for service without cutting it.
  • Kit-matched replacement - the same straight Accuair fits inside its systems.
  • Cheap against downtime - eleven dollars beats a stalled install waiting on a fitting.
