Precision machine shop and component supplier in Rochester, NY
Spex uses a variety of materials and machining processes to manufacture millions of precision metal parts.
Get leak-tight components that protect sealing surfaces and keep lines running without rework. Valve bodies, fittings, and adapters arrive clean, burr-free, and consistent in corrosion-resistant alloys—ready for assembly and pressure testing.
Operate confidently in harsh media. Corrosion-resistant components—machined in 316L, Alloy 20, Hastelloy, and more—feature smooth finishes and certification packages suited for CIP/SIP and regulated environments.
Build reliable power and electrical equipment with parts that fit, finish, and install right away. Connector bodies, standoffs, bushings, and hardware ship with clean threads, stable dimensions, and materials suited to your application.
Hit accuracy targets without chasing variation. Ports, sockets, stems, and diaphragm housings arrive with clean internal passages, precise geometry, and documented traceability for gauges, sensors, and control systems.
Streamline coil, valve, and manifold builds with components that braze, plate, and assemble cleanly. Fittings and couplings are delivered consistent at scale and resistant to corrosion for long service life.
Keep pumps and hydraulics on spec and in service longer. Housings, pistons, glands, and connectors are delivered concentric, smooth-bored, and heat-treat/plating compatible for high-pressure, continuous-duty environments.
Reduce downtime with durable, repeatable parts for heavy use. Shafts, spacers, bushings, adapters, and custom hardware show up tough, field-serviceable, and cost-controlled for production schedules.
Depend on small parts that make a big difference. Custom fasteners, pins, inserts, and miniature turned components hold tight tolerances and consistent cosmetics from pilot runs through high volume.
If your product relies on precision machined metal parts, you’re in the right place. Share your print and operating conditions—materials, finishes, and delivery programs are tailored to your targets.
