    3/8" NPT Regulator

    Description

    3/8 NPT Regulator For Stable Air Control

    3/8 NPT regulator from Milton Industries is a mid-size, relieving type air regulator designed to hold stable downstream air pressure across a wide range of air flows. The relieving design maintains set pressure while venting excess downstream pressure, which helps keep tools running at a consistent setting during changing demand. The unit controls air from 2 to 125 PSI, giving flexibility to match pressure requirements for different pneumatic tools on the same line. A maximum inlet pressure of 250 PSI allows this regulator to be used on higher-pressure shop systems while still maintaining the desired outlet range. The balanced piston inside the aluminum die cast body works with the molded rubber seat to provide accurate control with fast response and minimal pressure drop, which supports efficient air use along long airline runs.

    Air Regulator Details That Support Daily Use

    • The aluminum die cast body resists typical shop conditions while keeping weight manageable, which simplifies mounting on existing air line brackets or manifolds during installation or changeouts.
    • The balanced piston design promotes accurate control and fast response, so downstream pressure stays closer to the setpoint when tools cycle on and off in regular shop workflows.
    • The molded rubber seat works with the piston to limit pressure loss through the valve, reducing unnecessary pressure drop that can otherwise cause reduced tool performance at the far end of the line.
    • The Buna-N diaphragm and O rings provide the sealing needed for the relieving action, supporting stable downstream pressure as demand shifts between different tools and workstations.
    • Two offset 1/4 gage ports can function as two 1/4 supply lines, allowing installers to tap additional runs or instruments from the same regulator body without adding separate tees.

    Installation And Air Line Connection Considerations

    The Milton Industries 3/8 NPT regulator connects with a 3/8 inch national pipe thread, aligning with common shop air plumbing for straightforward integration into existing manifolds or drops. The two offset 1/4 gage ports give flexibility for positioning gages or secondary lines where they remain visible and accessible in the work area. Regulators should always be preceded by a filter, which protects the aluminum die cast body, piston, molded rubber seat, Buna-N diaphragm, and O rings from contaminants that can affect air flow accuracy. With an operating temperature range from 40 degrees Fahrenheit to 120 degrees Fahrenheit, this regulator suits typical indoor shop and production environments where compressed air tools and automation are used throughout the day.

    Using This Air Regulator In Shop Systems

    Where This 3/8 NPT Regulator Performs Best

    This mid-size 3/8 inch NPT air regulator is part of the filter/regulator/lubricator class, so it fits naturally into air line component stations feeding multiple tools. A maximum of 80 standard cubic feet per minute at 100 pounds per square inch matches many small to medium air distribution branches, providing enough flow for typical tool groups without starving downstream devices. Stable downstream pressure over a wide range of air flows helps reduce variation when several tools share the same header, which is important in woodworking and production lines that rely on repeatable air-driven operations. The relieving type design supports consistent pressure when flow changes, keeping actuator and tool behavior more uniform from cycle to cycle.

    Why These Regulator Details Matter For Results

    The 2 to 125 PSI control range lets installers dial in different outlet pressures for various applications without changing regulators, supporting both lighter tools and higher-demand equipment from the same feed. A maximum inlet pressure of 250 PSI gives additional margin on systems that operate above 125 PSI while still needing a controlled outlet, which can simplify system layout. The balanced piston, molded rubber seat, and Buna-N diaphragm work together to deliver accurate control, fast response, and minimal pressure drop, helping maintain tool power while managing air consumption. Operating between 40 and 120 degrees Fahrenheit keeps performance consistent across normal shop temperature swings, which supports predictable behavior of downstream tools and devices during seasonal changes.

    Common Questions About This Milton Air Regulator

    What inlet pressure can this Milton 3/8 NPT regulator handle?

    The 3/8 NPT regulator has a maximum inlet pressure of 250 PSI, allowing it to be used on higher-pressure supply lines while still controlling outlet pressure within its 2 to 125 PSI range.

    What outlet pressure range does the 1114 air line regulator control?

    The regulator controls air from 2 to 125 PSI, giving flexibility to support different pneumatic tools and devices that require distinct working pressures on the same line.

    How much air flow can the 3/8 inch NPT air regulator support?

    The mid-size regulator offers a maximum of 80 standard cubic feet per minute at 100 pounds per square inch, which aligns with many small and medium shop air circuits.

    What is the operating temperature range of this relieving type air regulator?

    The 3/8 NPT regulator operates from 40 degrees Fahrenheit to 120 degrees Fahrenheit, matching typical indoor shop and production environments for compressed air systems.

    How do the 1/4 gage ports on this air regulator function in a system?

    The regulator has two offset 1/4 gage ports that can serve as two 1/4 supply lines, enabling additional runs or instruments to be fed directly from the regulator body.

    Why is a filter recommended before this aluminum die cast regulator?

    The regulator should be preceded by a filter to protect the aluminum die cast body, balanced piston, molded rubber seat, and Buna-N components from contaminants that affect air control.

    Select This Regulator For Controlled Shop Air

    The Milton Industries 3/8 NPT mid-size regulator, part number 1114, combines a balanced piston, relieving type design, and 2 to 125 PSI control range to stabilize downstream air pressure in active shop systems. An 80 SCFM rating at 100 PSI and maximum 250 PSI inlet capacity align with many compressed air layouts serving multiple tools. The aluminum die cast body with Buna-N diaphragm and O rings supports accurate control, fast response, and minimal pressure drop. For air line stations that need stable, adjustable pressure within typical indoor temperatures, this regulator offers a practical fit for daily use.
