3/8" John Guest to 1/4" BSPT Male Adapter

This fitting threads a 3/8" John Guest push-in tube line into a 1/4" BSPT tapped port, commonly needed at espresso machine water inlet valves and boiler fill solenoids.

SPECIFICATIONS

  • 3/8" John Guest push-in x 1/4" BSPT male tapered thread

COMPATIBILITY

  • Fits: 3/8" OD push-fit tube systems needing to thread into a 1/4" BSPT tapped port - common on espresso machine water inlet valves and boiler fill solenoids

INSTALLATION

DIY - the BSPT thread is tapered and self-seals with PTFE tape; the push-fit side needs no tools.

PRO TIPS

  • BSPT threads seal on the taper itself, so two or three wraps of PTFE tape (wound clockwise as viewed from the pipe end) is normally all you need - avoid cranking it down past hand-tight plus about a turn and a half, or you risk cracking the fitting boss.
