3/8" John Guest to 3/8" BSPP Female Straight Adapter

This fitting converts 3/8" John Guest push-in tubing to a 3/8" female BSPP (British Standard Parallel Pipe) straight thread, giving you a reliable transition point for European-spec plumbing fittings on filtration and water supply lines.

SPECIFICATIONS

  • 3/8" John Guest push-in x 3/8" female BSPP straight thread

COMPATIBILITY

  • Fits: 3/8" OD push-fit tube systems that need to connect to a 3/8" BSPP threaded port - common on water filtration and RO fittings

INSTALLATION

DIY on the push-fit side; the BSPP side is a parallel thread that seals with a bonded washer or fiber seal rather than tape.

PRO TIPS

  • BSPP is a straight, parallel thread that seals via a bonded washer, not by tapering into the port - don't confuse it with BSPT and wrap it in PTFE tape expecting a taper seal, or you'll strip the fitting trying to force a seal that was never designed to form that way.
