Stainless steel dome caps and cones, spun and machined on our CNC lathes. Domes spread load and shed media off the axis; machined seat diameters keep them fitting the mating bore precisely.
Function and Design
A cap’s whole job is a clean, controlled close – of a tube, a port or an assembly. Drawn caps close with a formed dome or radius rather than a flat crimp, which is why they do not crack or leak the way cheap stamped closures do.
What Makes It Work
- No plating to scratch: stainless handles washdown, humidity and process media directly.
- Parts ship deburred and clean, packed to arrive assembly-ready.
- Made to your drawing – this listing shows the dome cap family range.
- Material: stainless steel (304 / 316), selected for the duty this dome cap sees; alternatives quoted against the drawing.
- Process: the dome cap is CNC machined – turning, milling and drilling in as few setups as possible.
- Finish: No catalogue finish: the dome cap surface is agreed on the drawing and confirmed at sample approval.
- Size: The dome cap is built to your drawing – the family covers the common range, your dimensions are quoted per print.
- Custom: Custom work to print for the dome cap, with DFM feedback before quotation.
Applications
Typical applications include automation and robotics hardware, pump and valve assemblies, instrumentation fittings.
Our Production Advantage
