CNC Machined Bushings & Housings
CNC machined bushings, blocks and housings — turned and milled to print, with bore and mounting faces held to drawing.
CNC machined adapters, unions and fluid fittings with sealed faces and threads cut to the specified standard.
| Materials | 6061-T6 / 7075-T6 aluminium, 45# carbon steel, 304 / 316L stainless, C360 copper, POM / nylon / PTFE |
|---|---|
| Tolerance | ±0.05 mm general tolerance, ±0.01 mm on critical features — held to print |
| Surface finish | As-machined, bead blasted, anodised Type II, zinc plated, passivated |

Adapters and unions are the fittings that join two different systems together, which makes their sealing face the part that has to be right. We machine the sealing face flat and square to the thread, cut the thread to the specified standard, and clean the sealing surface so it will actually seal when the customer fits it.
The ranges below are what this shop typically holds. Anything tighter than the baseline is possible — send the drawing and we will confirm it against your specific tolerances rather than quote from a table.
