Description

John Guest 1/2″ NPT x 3/8″ Tube Push-Fit Adapter

A John Guest push-to-connect fitting with 1/2″ male NPT threads on one end and a 3/8″ tube push-fit on the other — no ferrules or compression nuts, the tube grips and seals itself once it’s pushed in fully.

SPECIFICATIONS

  • 1/2″ male NPT x 3/8″ push-fit tube connection

COMPATIBILITY

  • Fits: any water line application using 1/2″ NPT threads and 3/8″ O.D. tubing

INSTALLATION

An easy DIY job — no tools needed for the tube side, just a wrench for the NPT threads.

PRO TIPS

  • Cut the tube end square and deburr it before inserting — an angled or burred cut is the most common reason a push-fit connection weeps at the collet.
  • Push the tube all the way to the internal stop, not just until it feels snug — a tube that’s gripped but not fully seated can pull loose under pressure even though it looked secure going in.
  • Keep this fitting away from cellulose paints, paint thinners, solder flux, and acid-based descalers or aggressive cleaners — they can attack the fitting’s seals over time.
