Triangle Machine Products is a trusted manufacturer of precision pneumatic stems engineered for critical industrial applications. We produce tight-tolerance components that play a vital role in the performance of valves, fittings, and pneumatic control assemblies. Whether used in automation systems, instrumentation, or fluid handling, our stems are machined to meet demanding dimensional requirements.
Pneumatic stems serve as key internal components that translate motion, regulate flow, or align mating parts within pneumatic assemblies. At Triangle Machine Products, we manufacture stems to your specifications, ensuring accurate diameters, concentricity, and surface finishes required for sealing, smooth actuation, or interference fit. Our equipment and inspection processes are designed for precision machining at scale—making us a reliable partner for both high-volume and short-run production.
No two pneumatic systems are alike—and neither are the stem components that keep them functioning. At Triangle, we specialize in custom pneumatic stem solutions built to your exact requirements. Whether you need a stem with specific threading, unique diameters, or challenging material needs, our team works closely with your engineers to ensure form, fit, and function. With decades of experience and investment in advanced CNC machining, we deliver consistency at every volume.
Unlike high-volume suppliers that prioritize speed over precision, Triangle Machine Products focuses on delivering pneumatic components with tighter tolerances, proper concentricity, and repeatable quality. We’re equipped to meet the needs of OEMs and tiered suppliers who demand high performance from every component. Our machining capabilities, combined with responsive service and deep experience in pneumatic applications, make us a reliable long-term partner for your pneumatic stem needs.
Pneumatic stems are precision-machined components typically used in pneumatic valves, couplers, and actuator assemblies. They are designed to facilitate controlled motion, flow control, or alignment within pressurized air systems.
Yes. We specialize in manufacturing custom pneumatic stems based on your drawings or specifications. We can accommodate a wide range of geometries, tolerances, and materials tailored to your application.
We commonly machine pneumatic stems from stainless steel, brass, carbon steel, and aluminum. We also offer plating, coating, or passivation based on corrosion resistance or application-specific needs.
