1 / Fluid interface
Port size, thread form, sealing method, connector interface and how the part meets the next component.

liquid-cooling block.
For flow blocks, multi-port bodies, connectors and liquid-cooling hardware, this page collects the material, thread, seal and RFQ details that help a factory review faster.
Buyer brief
What this page is for.
Many liquid-cooling enquiries arrive with a product image but without the information needed to quote. This page separates three things: the confirmed product evidence, the engineering data to confirm, and the files to send.
- Confirmed material: 316 stainless steel
- Confirmed process: custom CNC machining to customer drawing
- Confirmed feature set: multi-port body, internal threads and connection features
- Scope: prototype and production quantities reviewed per project
The strongest liquid-cooling enquiries include four details.
2 / Critical dimensions
Port location, body width, clearance, bore alignment, depth and any features that affect flow or assembly.
3 / Appearance and finish
Whether the mating face is hidden or visible, preferred surface texture, color, PVD or passivation, and visible thread areas.
4 / Production expectation
Prototype quantity, batch size, inspection record, target date and whether the part will be pressure-tested or leak-tested.
Scope of review: Our manufacturability review is based on drawings, material specification, process capability and in-house inspection. If your project requires certified inspection reports or material certificates, let us know in the RFQ.
What the confirmed product image shows.
This part is presented as drawing-based custom machining evidence. It is not a claim that Zhenglong holds a liquid-cooling certification, a pressure rating, or a specific industry approval. If the buyer needs pressure, temperature, food, medical or safety qualification, that must be defined in the project scope.
What to send with the RFQ.
- STEP, STP, PDF or DWG drawing
- Material confirmation, usually 316 stainless steel
- Quantity split between prototype and production
- Surface finish and any PVD, passivation or sealing requirements
- Thread form, port size and critical dimensions
- Inspection expectation and destination
The fastest quote comes when the buyer marks the critical features, not just the overall part size. For liquid-cooling hardware, the threads, port alignment and sealing faces usually decide both price and process route.

about 316 flow hardware.
What is the scope of your liquid-cooling work?
We machine drawing-based 316 stainless parts for liquid-cooling applications. Pressure rating, temperature limits and system qualification are defined in each project specification and confirmed with the buyer before quoting.
Can you produce both the port body and the internal thread features in one pass?
The confirmed 316 stainless part includes a multi-port body, internal threads and connection features. The machining strategy and fixture plan are reviewed against the drawing before production.
What quantity do you support for this type of part?
Prototype and production quantities of 1,000+ pieces are supported. The process and inspection requirements are reviewed against each drawing before quoting.
What surface finish options are available for 316 stainless?
Polishing, brushing, sandblasting, PVD coating, electroplating and passivation can be reviewed. State which surfaces are visible, which are hidden, and whether any face requires a specific roughness value.
What files should I send for the fastest quote?
Send a STEP or STP model, a PDF or DWG with critical dimensions marked, material confirmation, quantities, finish by area, thread form and port size specifications.
Finishing scope: Machining and inspection are handled in our Dongguan workshop. Polishing, brushing, blasting and engraving can be completed in-house. PVD, plating and passivation-related partner processes are coordinated with qualified suppliers where required.
