Fittings
6CNC manufactures CNC machined fittings, adapters, couplings, and fluid connectors when a standard part does not match your design. We review the thread, passage, sealing interface, material, and inspection requirements before production.

Fittings for Your Application
Each component is manufactured to your requirements. These examples help identify the geometry and interfaces to discuss with 6CNC.
01
Hydraulic fittings
Hose ends, adapters, and ORB or JIC interface components made to the supplied sealing and thread requirements.
02
Pneumatic components
Quick-connect components, push-in fitting bodies, and valve-related parts for specified air-system designs.
03
Pipe & tube fittings
Elbows, tees, reducers, couplings, and threaded pipe or tube connectors with defined connection standards.
04
Specialty adapters
Bulkhead fittings, multi-port blocks, and custom reducers for projects with nonstandard interfaces.
Engineering review
Custom Connections for Your Fluid System
Start with the features that determine fit, function, and acceptance. 6CNC reviews these requirements before confirming the manufacturing route.
01
Name the complete thread specification
Provide thread form, size, pitch, class, and gauging requirements. NPT, BSP, ORB, and JIC interfaces must be reviewed against their specific callouts.
02
Define how the connection seals
Identify the sealing face, groove, taper, or mating seat, together with surface condition and the mating component.
03
Plan passage and burr inspection
Specify cross-holes, internal transitions, edge condition, and cleanliness. Agree any leak or pressure testing, media, acceptance criteria, and documentation.

Fittings Machining Specifications
Use these published 6CNC reference ranges to begin your enquiry. The quotation confirms what applies to your actual part.
| Item | Published scope & project review |
|---|---|
| Materials | Brass, stainless steel, aluminum, carbon steel, and titanium. |
| Published size reference | 1/8–4 inches; custom sizes require drawing review. |
| Critical-feature tolerance | ±0.005–±0.02 mm reference for suitable sealing and thread-related features; thread acceptance follows the specified standard and gauge. |
| Quantity | 1–600 pieces, from prototypes to small and medium runs. |
| Processes | CNC turning, Swiss machining, 5-axis milling, and thread rolling where appropriate to the geometry. |
| Finishing options | Polishing, anodizing, nickel or zinc plating, passivation, and black oxide, subject to substrate and application compatibility. |

Material and Finish, Planned Together
Specify the material
Specify the alloy, fluid, temperature, and corrosion requirements. Material and component design must be reviewed together; a material name alone does not establish a pressure rating.
Define the finished condition
Coordinate plating build-up with thread fit and sealing dimensions. Identify internal passages or functional surfaces requiring masking, cleaning, or a specified final condition.
Manufactured by 6CNC
Inspection Follows the Features That Matter
6CNC plans thread gauges, sealing-feature measurements, concentricity checks, and agreed pressure or leak testing around the drawing. Define test conditions before the quotation is finalized.
01
Review the drawing
Confirm the material, geometry, critical features, quantity, and acceptance requirements.
02
Agree the route
Plan machining, workholding, any outside treatments, and inspection checkpoints.
03
Machine & finish
Produce the agreed drawing revision and coordinate the specified finishing sequence.
04
Inspect & prepare
Complete the agreed checks, documentation, and packaging for the order.
Before you enquire
Fittings Machining FAQ
Can you supply custom thread combinations?
Send the complete callout for each end, the mating parts, and the sealing method. 6CNC reviews the required tooling, access, and gauging.
Are the fittings automatically pressure-rated?
No. Provide the design rating, service conditions, applicable requirements, and test scope. The agreed design and verification determine acceptance.
Can surface treatment change the thread fit?
Yes. Specify whether dimensions apply before or after treatment and identify the required final thread gauges and sealing surfaces.
