Midland Industries 46074 Brass Drain Cock 1/8 in Mip 150 Psi

Product Description

The MIDLAND INDUSTRIES 46074 is a brass drain cock designed to control the release of low-pressure air, water, and compatible fluids from plumbing and mechanical systems. Rated to 150 psi and 250 degrees F, it connects via a 1/8 inch male iron pipe (MIP) thread and features a wing nut handle for manual operation. The internal seat design provides a positive shutoff when the valve is closed. At 0.03 pounds, this is a compact, lightweight fitting suited for residential and light commercial service work. Plumbers and HVAC technicians install it as a drain or bleed point on boilers, compressed air lines, water distribution systems, and similar low-pressure piping.

This drain cock is used in residential and light commercial applications where a manual drain or bleed point is required on a piping system. Common install locations include boiler drain connections, compressed air line drains, water supply branch lines, and irrigation system draindowns. The 1/8 inch MIP thread makes it compatible with standard pipe fittings at that size. The wing nut handle allows the valve to be operated by hand without tools, which is practical in tight or low-clearance locations.
