Multi-Port High-Seal Connectors
Custom CNC machined multi-port high-seal connectors — 4 to 12 sealing interfaces on one compact body (60×60×40 mm typical), all sealing faces Ra 0.8 µm and flatness ≤ 0.01 mm per face, 100% pressure-tested at 1.5× rated pressure. For vacuum, gas, hydraulic, and precision fluid system integration points.

Machining Challenges
Multi-Port Sealing Connector Challenges
A multi-port connector concentrates the sealing challenge — every face must independently seal while all port positions must be accurate for system assembly. Any single face that leaks defeats the entire connector.
🔒
All Faces Must Seal Independently
Each of the 4–12 faces on a multi-port connector must provide a leak-free sealing surface. HXC fly-cuts every sealing face as a dedicated final operation, achieving Ra 0.8 µm and flatness ≤ 0.01 mm on each.
⊕
Port Position Accuracy Across Faces
Ports on different faces must be positionally accurate relative to each other — a misaligned port on face 3 misaligns the system connection. All port positions verified by CMM against a single coordinate origin.
🏗️
Compact Wall Sections
Dense port layouts create thin walls between adjacent O-ring grooves. Minimum wall ≥ 3 mm is required for structural integrity — DFM review checks every wall section before machining.

FAQ
Multi-Port Sealing Connector — FAQ
Engineering and procurement questions answered by our team.
Every sealing face is machined as a dedicated final fly-cut or ground operation after all port drilling and tapping. Each face is machined last — after adjacent operations that could affect flatness. Every connector is then pressure-tested at 1.5× rated pressure on all ports simultaneously — a single leak on any face rejects the part.
All port positions on all faces are measured by CMM in a single setup referenced to the connector's primary datum. The CMM programme measures every port centre on every face and reports position (X,Y,Z) relative to the datum. Port position tolerance: ±0.01 mm across all faces.
Minimum structural wall between adjacent O-ring grooves: 3 mm for aluminium at ≤ 20 bar. For high-pressure (>100 bar): minimum 5 mm. For vacuum CF flanges: minimum 8 mm (CF standard). HXC's DFM review checks every wall section before machining begins.
Yes — multi-fluid connectors (e.g., compressed air + vacuum + coolant + signal gas on separate ports) are routinely machined. Internal cross-contamination is prevented by: (1) separate, non-intersecting internal channels; (2) CMM-verified channel separation walls; (3) independent pressure test of each fluid circuit.
HXC machines all standard fluid system interfaces on the same connector: BSP, NPT, metric ISO for general fluid; VCR face seal, CF, KF for vacuum and high-purity gas; SAE straight thread O-ring boss for hydraulic. Different faces of the same connector can use different standards — all specified on the drawing.
Yes — vacuum-rated multi-port connectors are electropolished on all internal surfaces and sealing faces: Ra 0.4 µm internal, Ra 0.8 µm sealing faces. Helium leak test to <1×10⁻⁸ mbar·l/s on all vacuum-rated ports. Cleanroom packaged with N₂ purge. Leak test certificate provided.
HXC has produced connectors with up to 12 ports on a 60 × 60 × 40 mm body (BSP 1/8" ports, 3 mm minimum wall). Port density depends on port thread size, working pressure, and wall strength requirements. DFM review confirms layout feasibility.
Prototype: 7–10 days. Small batch (10–50 pcs): 12–18 days. Production: 16–24 days. Vacuum-rated with helium leak test: add 2–3 days.
