Standard stainless steel 304 316L coupling 6NJ

Standard stainless steel 304 316L coupling 6NJ is a precision CNC machined component supplied by HIQTECO for hydraulic, pneumatic, instrumentation, rail, semiconductor and new-energy equipment. The component is produced using CNC machining, deburring and ultrasonic cleaning from 304 / 316 / 316L stainless steel, with dimensions, threads, surface finish and inspection requirements confirmed to drawing or sample.

Custom Standard stainless steel 304 316L coupling 6NJ Manufacturing

HIQTECO reviews material, critical dimensions, tolerance, surface finish and inspection requirements before production. We support prototype quantities, repeat orders and drawing-based customization. In addition, our team can coordinate secondary operations such as finishing and assembly when the component requires them.

• Material: 304 / 316 / 316L stainless steel depending on model
• Process: CNC machining, deburring and ultrasonic cleaning
• Configuration: tube, thread or weld connection as shown in the product title
• Packaging: standard export packaging
• Applications: hydraulic, pneumatic, instrumentation, rail, semiconductor and new-energy equipment

Material, finishing and inspection

Material selection depends on strength, corrosion resistance, machinability and the working environment. We work with 304 / 316 / 316L stainless steel and confirm the material condition before production. Finishing options can include anodizing, passivation, plating, heat treatment, sandblasting and marking. For example, a machined surface may require a specific finish to support sealing, wear resistance or appearance.

Applications for Standard stainless steel 304 316L coupling 6NJ

The part is intended for hydraulic, pneumatic, instrumentation, rail, semiconductor and new-energy equipment. At the same time, dimensions and features can be adapted to a customer drawing or sample. Typical applications include hydraulic, pneumatic, instrumentation, rail, semiconductor and new-energy equipment.

Quality control and documentation

We plan inspection around the drawing and the functional risk of the part. Incoming material verification, in-process checks and final dimensional inspection help keep production consistent. As a result, critical features can be checked with suitable measuring equipment, and inspection reports can be agreed before the order. Our quality process is aligned with ISO 9001 quality management principles.

Available production support includes prototype review, first-article inspection, repeat batch planning and export packing. Share the target quantity and delivery schedule so the quotation reflects the right production route.

Stainless Steel Coupling for Tube Connections

This stainless steel coupling connects tube sections in hydraulic, pneumatic and instrumentation systems. For example, the bore, end face and outside diameter are checked against the mating tube. In addition, 304 and 316L stainless steel cover different service conditions.

A stainless steel coupling should match the tube size, finish and assembly method. Therefore, HIQTECO reviews the drawing and material before production. As a result, the coupling can support a stable connection and a repeatable build. In addition, cleaning and inspection can be included.
