PSB & PSP Series screw couplings can be connected and disconnected even with a low rhigh pressure screw connect couplingsesidual hydraulic pressure in the line. The screw connection mechanism eliminates Brinelling (indentation of the locking balls into the retaining groove) and thus makes the couplings suitable for high pressures and pressure pulse applications. Two sizes are offered, 1/4″ and 3/8″ NPT.
