Yes. We regularly machine components for both high-pressure and low-pressure gas and fluid delivery systems. Our machining capabilities allow us to hold tight tolerances and produce parts that perform reliably under a wide range of operating pressures.
Absolutely. We use advanced tooling and process controls to ensure critical sealing faces, threads, and mating surfaces meet your specifications. Our quality assurance team inspects these surfaces for finish quality and dimensional accuracy, ensuring proper fit and long-term performance in your gas or fluid handling system.
We take extra precautions when packaging delicate machined parts. Threaded components can be protected with caps or plugs, and sealing faces can cushioned to prevent damage during transit. Some parts can be packaged in trays to prevent damage during shipping. We also use corrosion-inhibiting packaging materials when necessary, so your parts arrive ready for immediate assembly.
Yes. We have the capability to machine complex internal ports, channels, and passageways that improve fluid flow and reduce turbulence. Our experience with custom valve bodies, manifolds, and fluid connectors allows us to create precision features that meet your flow requirements while maintaining strength and durability.
