CUSTOM PNEUMATIC COUPLERS FOR INDUSTRIAL APPLICATIONS

Pneumatic couplers play an essential role in connecting air hoses and tools in a fast, secure, and leak-free manner. The integrity of these connections depends heavily on the performance of internal components—often invisible but critical to the function of the assembly. Triangle Machine Products produces machined coupler components such as sleeves, plugs, valves, retainers, and locking mechanisms, all designed to ensure durability and precision during repeated cycles of connection and disconnection.
Our parts are manufactured to tight tolerances to help reduce air leaks, ensure compatibility across mating parts, and maintain the strength and integrity of the full coupler system. These components are often subject to significant wear and pressure changes, making material selection, dimensional stability, and surface finish key priorities during production.

Triangle specializes in producing custom pneumatic coupler components to meet the specific geometries, material grades, and performance requirements set by each customer. Whether you need a modified profile for a high-flow design, specialty threads, or nonstandard engagement features, our team can machine to your exact print or support you in refining a design for manufacturability.
We accommodate both prototype and high-volume production runs and can work with various internal geometries and critical fit features. Our experienced engineers and machinists understand the small details—like chamfers, grooves, bore tolerances, and sealing surfaces—that make the difference in final coupler assembly performance. While other processes like cold forming may be suitable for looser tolerances, our CNC machining ensures repeatability and precision where it matters most.

OEMs and pneumatic system manufacturers choose Triangle Machine Products for our consistency, precision, and partnership approach. We don’t just supply parts—we support long-term manufacturing programs with reliable quality, short lead times, and responsive communication. Our facility is equipped to handle complex geometries, high-volume production, and tight turnaround times without compromising tolerances.
Our focus on machining—not forming or casting—positions us to deliver coupler components that require exact dimensional control and surface finishes that directly impact sealing and cycle life. With quality built into every stage of production and inspection, you can trust Triangle to be your go-to partner for pneumatic coupler components that support both function and long-term reliability.
