Product Introduction
1/4 Inch Inner and Outer Brass Ball Valve
G1/4 M×F Compact Ball Valve for Air Compressor and Pneumatic Lines
Compact M×F Shut-Off Valve for Pneumatic Lines
This 1/4 inch inner-and-outer ball valve provides a manual shut-off point in an air-compressor or pneumatic line. One end uses a G1/4 male thread and the other uses a G1/4 female thread, allowing the valve to connect directly between a tank outlet, a Y-joint, a fitting or a short air hose.
The 36.0mm body is intended for compact pipe layouts where a full-size valve would take up unnecessary space. Before ordering, confirm which side of the existing assembly needs the male thread, which side needs the female thread, and whether the green butterfly handle has enough room for a 90° turn.
Technical Profiles & Materials
G1/4 Inner and Outer Thread Connection
The valve uses a 1/4 inch G1/4 M×F connection. The listed male-thread outside diameter is 13.15mm, the female-thread inside diameter is 11.45mm, and the thread pitch is 1.337mm / 19 TPI. This arrangement allows the valve to be placed between a male-threaded outlet and a downstream fitting or hose connection.
Compact Brass Valve Body and DN6 Passage
The body is specified as high-quality metal / brass with a copper-color machined and passivated or nickel-protected finish. The listed internal passage is DN6 / Φ6.0mm and the overall body length is 36.0mm, giving the valve a short straight-through flow path for compatible low-pressure air lines.
Chrome-Plated Brass Ball, Copper Stem and PTFE Seat
The internal assembly uses a hard-chromed brass ball, a copper anti-blowout stem and a PTFE seat. The green butterfly handle is designed for a 90° manual opening and closing movement. Confirm the complete system's pressure, temperature and fitting condition before selecting the valve.

Products Application
Air-Compressor Line Shut-Off
Install the valve in a compatible compressor branch when a short manual shut-off point is needed. Check the M×F direction and keep the butterfly handle clear of the compressor housing and nearby tubing.
Air-Storage Tank Outlet Control
The valve can be placed at a compatible storage-tank outlet to open or close the downstream air branch. Confirm the outlet thread, the required connection direction and the working conditions of the tank-side assembly before installation.
Pneumatic Tool and Equipment Lines
Use the compact valve in compatible pneumatic-tool or equipment lines where a manual 90° shut-off is useful. Match the DN6 passage, air pressure, temperature, medium and hose or fitting arrangement to the complete system.
