Precision Parts Manufacturing for Oil & Gas
DEK provides precision CNC machining of custom parts for the oil and gas industry, built for the high-speed, high-volume and corrosive environments the sector imposes. As an ISO 9001-certified manufacturer, we hold tolerances as tight as ±0.005 mm and follow industry standards such as API and NACE.
We specialize in corrosion-resistant materials such as Inconel and Monel, with finishes including anodizing, QPQ, nitriding and passivation. Typical applications: MWD/LWD parts, drill string components, downhole motors, casing and cementing accessories.
What Oil & Gas Buyers Need
- Tight tolerances on leak-proof seal parts, casing heads and flanges
- Machinists who control work hardening and heat in Inconel 718
- Lead times based on real material availability and capacity
- NDA-protected designs on access-controlled servers

Typical Oil & Gas Components
From valve stems to tubing hangers, we machine components that run in high-pressure, corrosive oil and gas environments.
-
Stainless Steel Valve StemValve stems in stainless steel, chosen for corrosion resistance and high strength in oil and gas service, held to ±0.005 mm. -
Inconel Valve StemValve stems in Inconel for high-temperature, corrosive service, machined with tools and processes that control work hardening. -
Monel Valve StemValve stems in Monel, a specialty corrosion-resistant alloy for oil and gas parts, delivered with material certificates. -
Flange and ConnectorLeak-proof flanges and connectors in alloy steel, chosen for its high strength and low-temperature impact toughness. -
Stainless Precision ShaftStainless steel shafts for oil and gas equipment, where corrosion resistance and high strength must hold over time. -
Precision Shaft, Small BatchPrecision shafts machined from a functional prototype to small-batch production, with no MOQ and CMM inspection reports. -
Tubing HangerTubing hangers and tubing head parts in alloy steel for high-pressure assemblies, supplied with CMM reports and material certs. -
QPQ-Treated Valve StemValve stems machined and finished in one order with QPQ or nitriding for wear and corrosion protection in oil and gas service.

-
Engineering Capabilities
Mechanical engineers with 10+ years in programming, machining, post-processing and materials review every drawing and return DFM feedback before the first chip is cut.
-
Fast Lead Time
In-house 3-axis and 5-axis capacity, no minimum order quantity, and quick-turn scheduling when a part is holding up a build.
-
Quality Control
In-process and final inspection on CMM (Coordinate Measuring Machine), with inspection reports, FAI reports and material certifications supplied on request.
-
Surface Finishes
Passivation, anodizing, electroplating, PVD and QPQ coating applied in line with machining, so corrosion protection is part of the same order.
