Eaton 705 Brass Air Vent Drain Cock Shutoff Valve

Product Description

The EATON 705 is a brass air vent drain cock shutoff valve designed for flow adjustment in plumbing and HVAC systems. With a 1/8 inch threaded connection and a maximum working pressure of 150 psi, this compact valve provides reliable on-off and flow control at air vent or drain points. The brass body offers corrosion resistance suited to wet piping environments. Licensed plumbers and HVAC technicians install this type of fitting during system commissioning, maintenance, and seasonal draining procedures. Its small form factor makes it a practical choice wherever a low-profile manual shutoff is needed at a vent or drain port.

This valve is used in residential and light commercial plumbing, hydronic heating, and HVAC piping systems wherever a 1/8 inch threaded drain or air vent port requires manual shutoff or flow adjustment capability. Common applications include boiler drain points, air separator vents, and auxiliary drain connections. The 1/8 inch thread size is standard for many small-port fittings found throughout hydronic and forced-air system piping assemblies.

Key Features

• Brass body construction for corrosion resistance in wet piping systems
• 1/8 inch threaded connection for standard small-port drain and vent fittings
• 150 psi maximum working pressure for residential and light commercial service
• Flow adjustment function allows throttling as well as full open and closed positions
• Compact, low-profile design suited to tight installation spaces

Compatibility

Designed as an OEM-style replacement or service fitting for residential and light commercial plumbing and hydronic systems requiring a 1/8 inch threaded drain cock or air vent shutoff valve rated to 150 psi.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician. Shut off system pressure and drain the affected line before removing or installing any valve. Apply an appropriate thread sealant or PTFE tape to the 1/8 inch male threads before assembly and tighten to hand-tight plus a moderate turn to avoid overtightening brass fittings. Verify the system does not exceed the 150 psi maximum rated working pressure of this valve.
