Product Description

The A Y MCDONALD aym-72008 3/4 is a no-lead brass boiler drain valve designed for low-pressure water service in residential and commercial plumbing systems. It features a 3/4-inch nominal size with a male NPT inlet and garden hose thread outlet, rated to 125 psi. The heavy-duty brass body and brass trim are paired with a rubber gland and seat packing for reliable positive shutoff.

The MNPT x garden hose thread configuration allows direct attachment to standard drain hoses without adapters.
