Air Plugs Kwik Change M Style, 1/4" Hose Barb

Air Plugs Kwik Change M Style For Hoses

Air Plugs Kwik Change M Style is a Milton Industries air line fitting designed as a barbed coupler plug with a 1/4 inch hose barb, so it connects directly to 1/4 inch air hose for dependable air tool service. The plug is made from case hardened steel, which gives the fitting a tough wearing surface that stands up to frequent couplings in busy shops. The steel plug is plated to resist rust, so the connection point stays cleaner and moves freely in typical woodworking and shop environments where moisture and dust are present. This M style plug is part of the air line components and air line fittings category, tying into standard compressed air layouts so air tools can be moved between stations without changing hose types. With its Milton Industries branding, the plug aligns with established shop air setups that rely on consistent performance.

Key Air Plug Details For Daily Use

• The plug is rated for a maximum inlet pressure of 300 PSI, which supports typical shop air systems so the same fitting can stay in place across a range of regulated pressures without swapping components during different tasks.
• The maximum temperature rating of 250 F means the plug is built to tolerate higher air and ambient temperatures, so the barb and sealing area keep performing in warm compressor rooms or near heat-generating equipment.
• This barbed coupler plug is designed with a 1/4 inch hose barb, creating a direct push-on connection to matching hose that maintains a consistent internal diameter for predictable air delivery.
• The plug provides an air flow rating of 40 SCFM, which supports substantial air volume, allowing many air tools and blow-off operations to run at their intended performance within that capacity.
• Seals are Buna-N, so the plug uses a widely used sealing material that supports air retention at the rated pressure and temperature, helping reduce leakage at the connection point over ongoing use.

Barbed Coupler Plug Setup And Hose Connection

This barbed coupler plug with 1/4 inch hose barb is intended for hose-based connections, so the barbed end engages directly with the inside of a 1/4 inch hose to create a secure mechanical grip. The barbed design on the Milton Industries plug helps hold the hose under system pressure up to the 300 PSI rating, which supports stable connections in fixed and mobile shop air runs. Because the plug is an M style air line fitting, it mates into matching Kwik Change couplers, creating a quick connect and disconnect point that speeds tool changeover. The case hardened steel body maintains its shape at the barb and plug interfaces, which supports repeatable sealing performance after multiple hose installations and removals. With the rust-resistant plating, the coupling surfaces resist corrosion from humid air, so the plug continues to connect smoothly even after long exposure on the shop floor.

How This Milton Air Plug Works In Practice

Where This 1/4 Hose Barb Plug Fits Best

This barbed coupler plug 1/4 is sized for air hose runs that use 1/4 inch internal diameter, so it fits directly into light to medium duty air lines common in woodworking and general shop service. By using the Kwik Change M style interface, the plug works within M style coupler systems, allowing hoses fitted with the Milton Industries plug to move between different outlets or tools that share the same style. The 40 SCFM air flow rating supports many air tool and air blow applications within that capacity, which keeps tools supplied with the volume they need when matched to appropriate regulators and hoses. The plug operates within a maximum inlet pressure of 300 PSI, so it can sit downstream of higher pressure compressors while still functioning properly in regulated circuits that stay within that rating. Its maximum temperature rating of 250 F supports use near compressors and heated spaces, where line temperature can rise yet remain within the plug's limits.

Details That Support Repeatable Air Line Results

The case hardened steel construction of this air plug provides a durable wearing surface at the coupling end, which helps the plug maintain a consistent profile that seals reliably in couplers over many connection cycles. The rust-resistant plating applied to the plug helps keep the metal surfaces smooth, supporting easy insertion and release even when the air system operates in humid or dusty shop environments. Buna-N seals inside the plug provide a sealing interface designed for compressed air, which supports reduced leakage at the connection, helping tools receive more of the available 40 SCFM air flow. The 1/4 inch hose barb forms a secure mechanical and sealing interface with 1/4 inch hose, which helps the hose stay in place when operating at pressures up to 300 PSI. The Milton Industries part number 736 identifies this specific M style, 1/4 inch hose barb configuration, helping installers repeat the same setup across multiple hoses or workstations to keep air connections consistent.
