John Guest 3/8" Stem x 1/4" Tube Push-Fit Reducer

A John Guest Speedfit push-fit reducing fitting that steps a 3/8" stem connection down to 1/4" tube, commonly used on water filtration and plumbing lines feeding espresso machines and water filters. Made of food-safe Acetal thermoplastic and rated for potable water use.

SPECIFICATIONS

  • Material: food-safe Acetal thermoplastic
  • Connection: 3/8" push-fit stem x 1/4" push-fit tube
  • Rated for potable water / food-quality liquid applications
  • Not suitable for compressed air or vacuum applications

COMPATIBILITY

  • Fits: water lines and filtration systems using John Guest Speedfit-compatible 3/8" stem and 1/4" tube connections

INSTALLATION

Simple DIY installation, push-fit, no tools required.

PRO TIPS

  • To disconnect, push the tube in slightly first to relieve tension on the O-ring, then press the collet squarely against the fitting body while pulling the tube straight out. Pulling at an angle can nick the O-ring and cause a slow leak later.
