Purchase a spanner wrench to tighten or loosen PF series size fittings. Each spanner wrench has a depth gauge built into the handle to aid you in a variety of installation jobs. These spanner wrenches range in size from 20mm (3/4") to 80mm (3") in length.
Note: PF Series fittings come pre-torqued from the factory and do not require any tighten for installation (verify white marks line up on fitting). Consult Installation and Assmebly Instructions
