China Custom CNC Turned Hose Barb Fittings & Threaded Adapters Manufacturers, Quotes

Shenzhen Sunmy Hardware Co., Ltd. manufactures custom hose barb fittings and threaded adapters for fluid-handling equipment, dosing systems and pneumatic assemblies. Send your drawing or sample to specify the hose connection, port thread, through-bore, material and finish as one made-to-order component, from prototypes to repeat production.

Need a different hose size, thread or installation length? We tailor barb geometry, insertion length, bore, sealing features and wrench access to your assembly. The illustrated straight adapter combines a multi-barb hose tail, male thread and axial passage. Final geometry, material and supply scope follow your approved drawing, not a fixed catalog configuration.

For custom straight adapters, our manufacturing review starts with CNC turning, bore machining and thread cutting. Formed blanks or tubular forming can be evaluated for suitable designs and volumes. The route is selected to suit your geometry, material and order quantity, with finishing and inspection agreed before production.

• CNC Turning & Secondary Machining: Turn the body, shoulders and hose-tail profile; drill and finish the axial bore to the drawing. Mill wrench flats or other non-rotational features where specified. For repeat volumes, compare suitable forming or rolling alternatives without changing approved interfaces.
• Hose-Specific Barb Geometry: Define barb crest diameter, pitch, taper, edge condition and insertion length around the selected hose and retention method. Review liner damage, assembly effort and pull-off requirements with the actual hose. Specialty or reinforced tubing requires its own compatibility assessment.
• Thread Form & Sealing Interface: Machine NPT, BSPT/R, BSPP/G, metric or Unified threads to their respective specifications. Tapered connections require the matching port and an approved sealing method; parallel connections require the specified sealing face and seal. Ring gauges verify external threads; plug gauges apply to internal threaded variants.
• Deburring, Cleaning & Surface Finishing: Remove machining chips and control burrs at bore entries, barb edges and thread starts without changing critical geometry. Select cleaning, passivation, plating or other finishing to suit the alloy and medium. Cleanliness limits, verification methods and protective packaging are agreed for the order.

All dimensions and interfaces are customizable to your drawings or approved sample. The options below are for project selection, not fixed stock sizes or universal performance ratings.

• Interfaces Matched to Your Assembly: Combine the required hose tail, thread, body length and tool access in one custom adapter. Review the mating-port and hose details before committing to samples or production.
• Bore and Hose Connection Reviewed Together: Tailor the passage diameter, transitions and wall thickness to the required flow and installation space. Identify functional roughness and flow-verification requirements before quotation so the hose connection and internal passage are reviewed together.
• Thread and Seal Requirements Kept Together: Define the thread family, size, pitch, applicable class and sealing geometry on one drawing. Allow for finishing on critical surfaces and agree the required thread gauges and inspection stage.
• One Contact for Multi-Process Sourcing: Coordinate turned fittings with related machined adapters, stamped brackets or molded components when your project needs them. Keep drawing revisions, finishing and supply boundaries aligned across the component set.
• Inspection Planned Around Critical Features: Agree dimensional, profile, thread and surface checks before manufacture. Leak, pressure or pull-off testing requires defined fixtures, conditions, acceptance criteria and sampling. Material records, FAI and other documentation are specified in the quotation.
