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

$10.95

3/8-inch DOT push-to-connect to 1/8-inch NPT straight fitting for classic truck air ride builds, connecting sensor bosses, gauge taps and small manifold ports to 3/8-inch line.

  • 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.

Install Level: Easy

SKU: AA-3654
