CA Technologies 53-573 quick disconnect coupling is a hi flow air line fitting that connects into an air system using a 1/4 inch male stem. This design delivers an air connection point that ties air tools or equipment into an existing line. The 1/4 inch male stem format creates a defined interface for air couplers that match this stem style. The component functions within air line systems that rely on quick disconnect points for changing tools. The product sits in the air line fittings class, so it works as a connection part rather than a tool. As an air line component, it supports air supply routing in shop environments where compressed air is used. The hi flow designation identifies it as a fitting aimed at higher air volume transfer compared with standard flow styles.
The 1/4 inch male stem on this coupling establishes one side of the air connection as a stem-style interface, affecting how the mating coupler grips the part. The 1/4 NPT male thread described in the SAP text defines the threaded connection standard on the coupling, which ties into air line components that use 1/4 inch NPT ports. As an air line fitting, the component functions as a link between threaded ports and quick disconnect couplers, shaping how an air system is laid out. Using the specific part number 53-573 keeps the thread type and stem style consistent across multiple drops in the same air layout.
This quick disconnect coupling uses a 1/4 inch male stem on the connection side, placing it in systems that require a stem-style plug for the coupler body. In an air line, that stem can serve as the point where air hoses or tools connect, depending on how the rest of the system is built. Because the product is classified as an air line component and air line fitting, it is intended to live within the compressed air infrastructure rather than at the tool body. The male stem dimension provides a standard shape for compatible couplers, which helps maintain uniform connection behavior at every drop where this stem is used. For installers, selecting this stem size keeps the plug style consistent through multiple air outlets that share the same fitting family.
The hi flow designation on the CA Technologies 53-573 coupling signals that the internal passage is aimed at higher airflow compared with general-purpose quick disconnect parts, which can help when air demand is a concern in a run. The 1/4 NPT male detail from the SAP description defines the threaded end, so every port that receives this stem must use 1/4 inch NPT threading for the part to seat as intended. Because the product sits in the air line fittings class, it acts as a junction between the threaded piping or manifold and the quick disconnect side, shaping how air routing can branch or extend. Using the same 53-573 part in multiple positions repeats both the hi flow behavior and the 1/4 NPT thread standard across a whole air network.
The CA Technologies 53-573 is a quick disconnect coupling in the air line fittings class, so it functions as a connection point within an air system layout.
The 1/4 inch male stem defines the plug side of the connection, so it mates with couplers designed for that stem size, keeping connections consistent along the air line.
The 1/4 NPT male description indicates that the threaded end uses 1/4 inch NPT threading, which determines which ports or manifolds the coupling can thread into.
This hi flow quick disconnect coupling is used within air line components, sitting between threaded air supply points and couplers that plug onto its 1/4 inch male stem.
The hi flow description shows that the coupling is intended for higher airflow capacity than standard styles, which matters in air systems serving demanding tools.
The 53-573 manufacturer part number uniquely identifies this C.A. Technologies fitting, allowing the same hi flow, 1/4 inch male configuration to be matched during replacements.
The CA Technologies 53-573 quick disconnect coupling pairs a hi flow design with a 1/4 inch male stem and 1/4 NPT male thread, aligning it with air line fittings built around these dimensions. Selecting this exact part number keeps the air interface consistent wherever it is used in a system. When an air line layout already uses C.A. Technologies air line components, this stem configuration follows the same product family and style. For installers organizing or extending compressed air runs, adopting a repeatable fitting such as this 53-573 model supports a uniform connection standard across drops.
