Precision Machining of Custom Hydraulic Fittings

Precision Machining of Custom Hydraulic Fittings

Hydraulic fittings often involve tight sealing surfaces, concentricity requirements, and complex threads such as BSPP, NPT, or UNF. Material hardness and sealing groove precision make machining challenging.

DEK utilizes multi-axis CNC lathes and live-tooling turning centers to ensure critical dimensions meet tolerance. Our thread gauges and high-pressure sealing tests guarantee functional performance. Surface treatments like passivation or anodizing are controlled per spec to prevent corrosion.

We support both prototyping and small-batch production, ensuring consistent quality with CMM inspection and process stability.

Live-Tool Turning for Threads

Our turning centers with live tooling handle external/internal threads like NPT, BSPP, UNF. Thread depths and minor diameters controlled by in-process gauging. Surface burrs removed with automated deburring tools.

Bore Concentricity Holding

Sealing bores are machined in one clamping to ensure coaxiality with threads. We monitor runout within 0.02mm using dial indicators and bore gauges.
