Eaton Aeroquip 120 Drain Cock

This brass drain cock provides a reliable shut-off point for fluid systems in automotive and HVAC applications. It features a 1/4 inch MNPT connection and an angle body style suited for tight installations. The wing handle allows quick manual operation without tools. It is designed for professionals maintaining radiators, boilers and similar equipment.

Brass construction and steel wing handle

The brass body resists corrosion from coolant and water while the steel wing handle withstands repeated use. Internal seat positioning helps create a positive seal when closed. These materials support an operating range from -65 degrees F to 250 degrees F. The assembly meets ASME 1016 standards for pressure-rated components.

150 psi maximum pressure limit

This valve is rated for a maximum pressure of 150 psi, so it cannot be used in higher-pressure hydraulic or industrial lines. The 1/4 inch MNPT thread requires a matching female port and does not adapt to other pipe sizes without additional fittings. Minimum temperature rating of -65 degrees F may not suit extreme cryogenic environments.

Questions about this item

Will the brass body or internal seat need replacement after years of service?

Brass construction resists corrosion, so the body and internal seat typically last the life of the system unless debris damages the sealing surface.

At 150 psi maximum pressure, will the valve leak or fail first during prolonged pressurised use?

The 150 psi rating is the design limit; sustained pressure at or above that level will cause leakage before structural failure of the brass body.

How hot does the steel wing handle get when fluid runs at 250 °F all day?

The steel wing handle conducts heat from the brass body, so it will reach near-fluid temperature and require gloves for safe operation.
