Eaton Aeroquip 185 Drain Cock

This Eaton Aeroquip 185 drain cock is a brass inline valve designed for draining fluid from radiators, boilers and similar HVAC systems. It suits maintenance technicians and installers who need a reliable shut-off point with a 1/8 inch male NPT connection. The wing handle allows manual operation without tools. It is rated for a maximum pressure of 150 psi.

Brass MNPT connection limits

The 1/8 inch male NPT thread restricts use to ports machined to that exact standard. The valve operates between minus 65 degrees F and 250 degrees F, so systems running hotter or colder fall outside its range. Brass construction resists corrosion in water-based circuits but is not suited for aggressive chemicals. The 150 psi ceiling excludes high-pressure hydraulic lines.

ASME 1016 compliance decides fit

Meeting ASME 1016 confirms the valve meets the dimensional and performance requirements for this class of drain cock. Buyers verifying code compliance for boiler or radiator installations can accept this part on that basis. If a project specifies a different standard or a higher pressure class, this valve will not satisfy the specification.

Questions about this item

Which size should I select for a 1/8 MNPT port?

The drain cock is manufactured with a 1/8 inch MNPT connection and a 7/16 inch hex, so the single listed size fits that port directly.

What does the 150 psi rating mean when the valve is installed in a system?

It indicates the maximum working pressure the brass body and internal seat are designed to contain at temperatures up to 250 °F.

How does the ASME 1016 standard affect installation?

ASME 1016 confirms the valve meets recognised dimensional and pressure requirements for inline drain service in piping systems.
