1/4" M x 3/8" M BSP Fitting

1/4" x 3/8" BSP Brass Fitting

Common parallel pipe fitting with a flat seat, used to connect 1/4" and 3/8" BSP threaded lines.

SPECIFICATIONS

• Overall length: 29 mm
• Wrench flats: 18 mm
• Internal diameter: 7 mm
• Material: Low-lead content brass (CW510L / OT57)

COMPATIBILITY

• Fits: Any application requiring a 1/4" M BSP to 3/8" M BSP flat-seat fitting

INSTALLATION

Simple DIY swap; the flat-seat design seals against a washer, not the threads.

PRO TIPS

• Because this fitting seals via its flat seat rather than tapered threads, check the condition of the mating seat washer/gasket, a worn washer, not the fitting, is the most common cause of leaks here.
