A Block of Metal Full of Precise Holes
A manifold block routes fluid or air between ports through a network of internal passages, with valve cavities and sealing lands controlling flow. From outside it's a tidy block; inside it's a 3D maze of intersecting drillings that must meet exactly, stay clean, and hold pressure. That internal accuracy and cleanliness — not the outside shape — is what makes a manifold demanding, and it's exactly what precision machining controls.

What We Machine Into a Manifold
- Drilled flow passages — intersecting bores routing port to port
- Threaded ports — to your fitting standard, sealing first time
- Valve / spool cavities — bored and finished for the seals
- Mounting faces — flat, to bolt to a pump or valve stack
- Plugged cross-drills — to close drilling access points
Clean, Sealed, Tested
The two things that ruin a manifold are a burr at a passage intersection (which breaks loose and jams a valve) and a leaking port. We cross-deburr every intersection, clean and flush the block, cut ports to the exact standard, and pressure-test before shipping. See our hydraulic valve body case for the same discipline, and our guide to replacing a discontinued hydraulic part.
Replacing an obsolete manifold? Send the old block or a drawing with the passage map and ports. We reproduce it in the right material and pressure-test it. No drawing? Start via no-CAD ordering.
Frequently Asked Questions
Both. From a drawing we machine the block, cross-drill the passages and cut the ports; from a sample we reverse-engineer the passage layout. We confirm the passage map and port standard before machining.
Every intersection is cross-deburred so nothing breaks loose downstream, then the block is cleaned and flushed, and pressure-tested on request.
BSP/BSPP, NPT/NPTF, metric and SAE O-ring boss — cut to standard so your fittings seal first time.
6061 aluminium for light/medium pressure, steel or stainless for higher pressure or aggressive media — selected with you by working pressure and fluid.
