OUR VERDICT

A full-flow straight-thru quick-connect for lines where pressure drop matters more than shut-off: test ports, high-flow air, water and fluid transfer. Shut the supply off before disconnecting. Mates with Foster FST and Dixon E-Series halves of the same size.

WHAT WE LIKE

Full-bore flow, no valve to restrict the line
Foster FST and Dixon E-Series interchange
Brass or steel body, simple and rebuildable

WORTH NOTING

No shut-off: the line is open when disconnected
Only couples with same-size straight-thru halves
