Stainless Steel Metric Hydraulic Fittings: Custom CNC Machining Solutions
Metric hydraulic fittings are essential components in hydraulic systems, helping connect tubes, pipes, hoses, and other fluid-carrying components. They are widely used in industrial machinery, hydraulic equipment, automation systems, and other applications that require reliable fluid connections.
At Zhejiang Dream Industry Limited, we specialize in precision metal machining and customized mechanical components. We offer custom metric hydraulic fittings made from 304 stainless steel, with manufacturing solutions tailored to customer drawings, dimensions, thread specifications, and application requirements.
Whether you need prototype components, small-batch production, or OEM manufacturing, we can evaluate your technical requirements and provide a suitable machining solution.
What Are Metric Hydraulic Fittings?
Metric hydraulic fittings are connection components designed around metric dimensional standards and thread specifications. They are used to connect hydraulic lines and related components while helping maintain a secure fluid connection.
Depending on their design, metric hydraulic fittings may feature straight threads, tapered threads, sealing faces, O-ring grooves, or other sealing structures. The appropriate configuration depends on the mating components, working pressure, fluid type, and installation requirements.
When selecting metric hydraulic fittings, buyers should confirm the thread standard, thread size, sealing method, connection geometry, material, and required operating conditions.
Stainless Steel for Metric Hydraulic Fittings
Stainless steel is a widely used austenitic stainless steel known for its corrosion resistance, formability, and general-purpose performance. It is a suitable material option for many industrial components exposed to moisture and a range of common operating environments.
Key characteristics of 304 stainless steel include:
Corrosion resistance: Suitable for many general industrial environments, subject to actual exposure conditions.
Mechanical performance: Provides a useful balance of strength, toughness, and formability for machined components.
Machining versatility: Can be processed using CNC turning, milling, drilling, tapping, and other suitable machining operations.
Wide industrial use: Commonly used in machinery components, fluid-handling equipment, and general industrial hardware.
The suitability of 304 stainless steel depends on the fluid, temperature, chloride exposure, pressure, and other operating conditions. For applications involving aggressive chemicals, high chloride concentrations, or demanding service environments, material selection should be evaluated carefully.
Precision CNC Machining for Custom Metric Hydraulic Fittings
Accurate dimensions and compatible connection geometry are important when manufacturing hydraulic fittings. Thread accuracy, sealing surfaces, concentricity, and other critical features may affect assembly and sealing performance.
Our custom machining services can support the production of metric hydraulic fittings according to customer drawings and agreed technical specifications.
Available machining processes may include:
CNC turning for cylindrical bodies, threaded sections, and precision diameters
CNC milling for flats, slots, and customized external features
Drilling and tapping for internal passages and threaded holes
Deburring and surface finishing to meet specified requirements
Dimensional inspection based on agreed drawings and critical tolerances
The manufacturing process is selected according to the component geometry, material, required quantity, and technical specifications.
Custom Metric Threads, Dimensions, and Sealing Designs
Different hydraulic systems use different connection standards. Therefore, metric hydraulic fittings should not be selected by thread size alone.
When requesting a custom fitting, please specify the following details wherever applicable:
Thread specification: For example, M12 × 1.5 or another specified metric thread
Connection type: Male thread, female thread, straight connector, adapter, or another configuration
Sealing design: O-ring seal, sealing face, bonded seal, or another specified arrangement
Dimensions: Overall length, body diameter, hex size, thread length, and other critical dimensions
Material: 304 stainless steel or another agreed material grade
Operating requirements: Working pressure, fluid compatibility, temperature, and applicable testing requirements
Surface requirements: Specified finish, cleaning, or other processing requirements
These details help reduce compatibility issues and allow the fitting to be manufactured according to the intended application.

FAQ
What material is used for these metric hydraulic fittings?
This product offering is based on 304 stainless steel. Final material specifications should be confirmed before production to ensure suitability for the intended fluid, temperature, corrosion exposure, and operating conditions.
Can you manufacture custom metric hydraulic fittings from drawings?
Yes. Custom components can be evaluated based on customer drawings, CAD or STEP files, or physical samples, subject to technical review and manufacturing feasibility.
Which metric thread sizes are available?
Thread sizes and pitches depend on the component design and customer requirements. Please provide the specified thread standard, nominal diameter, pitch, and mating connection details for confirmation.
Are 304 stainless steel hydraulic fittings suitable for high-pressure applications?
Suitability depends on the fitting geometry, wall thickness, thread design, sealing structure, material properties, manufacturing quality, and verified test results. A pressure rating should not be assumed from the material grade alone.
How can I request a quotation?
Please send your drawings or samples along with the required quantity, material specification, thread details, sealing requirements, operating conditions, and inspection requirements. These details help us assess the project and prepare a more accurate quotation.
