John Guest 1/2" Stem x 3/8" Push-In Reduction Connector

A genuine John Guest push-fit reducing connector that steps a 1/2" push-in fitting down to 3/8" tubing, letting you run smaller-diameter tubing from a larger supply line without swapping out existing fittings.

SPECIFICATIONS

  • Stem size: 1/2"
  • Push-in size: 3/8"
  • Type: John Guest push-in connector

COMPATIBILITY

  • Works with: 1/2" push-in fitting systems needing a 3/8" tubing run

INSTALLATION

Simple DIY installation, push-fit design requires no tools.

PRO TIPS

  • Cut the tubing end square and deburr it before inserting, an angled or burred cut is the most common cause of push-fit connectors leaking or not gripping properly.
  • To remove, push in on the tubing slightly while pressing the collet ring evenly, then pull the tube straight out, pulling at an angle can damage the internal o-ring.
