Air Plugs Kwik Change M Style, 1/4" NPT Female

Air Plugs Kwik Change M Style For Shop Air

Air Plugs Kwik Change M Style, 1/4" NPT Female from Milton Industries is a female coupler plug designed as part of an air line fittings system, so it lets you connect tools or hoses using a standard threaded interface in a compressed air setup. The 1/4" NPT female thread provides a common connection size, which helps keep fittings consistent across many air line components in a shop environment. As an air line component, this plug fits into a broader compressed air layout, so installers can route and terminate air supplies where needed on benches or machines. The product is identified by manufacturer part number 728BK, which ties directly to Milton Industries documentation for matching with other M Style pieces during planning or rework. Classified under Air Line Components and Air Line Fittings, it plays a focused role in managing compressed air flow between source and point of use.

Key Air Line Plug Details For Daily Work

• The plug is made from case hardened steel, which gives the fitting a tough working surface that stands up to repeated couplings in active air systems.
• The steel plug is plated to resist rust, so exposed shop moisture is less likely to affect the fitting surface over time in normal air line layouts.
• The plug supports a maximum inlet pressure of 300 PSI, which allows it to function within typical compressed air system pressures without exceeding its stated limit.
• The maximum temperature rating of 250 F allows the plug to operate in warm air conditions, so installers can use it where air or ambient temperatures rise in routine shop use.
• The plug provides an air flow capacity of 40 SCFM, which helps maintain sufficient volume for many air-driven tools when the fitting is used in the correct part of the line.
• Buna-N seals are used in the plug design, giving the sealing surfaces a material known for compatibility with compressed air and helping support an effective air seal.

Threaded Air Plug Setup And Connection Use

This Milton Industries air line plug is configured as a 1/4" NPT female fitting, so it threads onto a matching male NPT connection when installers are building out or modifying an air circuit. As an M Style plug within the Air Line Fittings product class, it works inside a system that uses that style as a standard, which can simplify layout when multiple drops or tools share the same interface. With a maximum inlet pressure of 300 PSI, the plug is suited for compressed air service up to that pressure rating, allowing it to function in many shop or jobsite air networks that stay within this range. The 40 SCFM air flow rating defines how much air volume can move through the plug, helping planners position it where that capacity aligns with tool demand. Its 250 F maximum temperature rating means the plug is assigned for environments where air and surrounding conditions remain at or below that value.

Using This Milton Air Plug In Real Jobs

Where This 1/4 NPT Female Plug Fits In

The Air Plugs Kwik Change M Style, 1/4" NPT Female plug belongs to Milton Industries air line fittings, so it is suited to projects that specify that brand and style throughout the air distribution system. As a female coupler plug with 1/4" NPT threading, it attaches to male threaded outlets on regulators, manifolds, or rigid pipe runs, creating a connection point that follows the same thread form as other air line components. The air flow rating of 40 SCFM positions this plug for lines feeding air tools or equipment that operate efficiently at that volume, which supports consistent performance when several outlets are balanced across a system. Within the Air Line Components category, this plug takes on the role of a transition point between fixed plumbing and quick-change connections, allowing each drop or station to share a consistent interface.

Details That Support Repeatable Air Line Results

The use of case hardened steel in this Milton Industries plug helps the coupling surfaces remain serviceable under frequent connect and disconnect cycles, which supports long-term alignment in quick-change setups. A plated finish that resists rust keeps the working surfaces clearer in humid or dusty shops, which helps the plug maintain its fit in mating components over time. The 300 PSI maximum inlet pressure defines the upper working pressure for the plug, giving planners a firm limit when mapping main trunks versus lighter duty branches in a compressed air layout. The maximum temperature rating of 250 F adds another boundary, signaling how the plug is assigned for air and ambient conditions that stay within that envelope. Buna-N seals inside the plug create the sealing interface against compressed air, supporting a consistent seal that helps air lines hold pressure between cycles. Together, these characteristics give installers a defined set of performance limits for designing repeatable air circuits.
