Brass Compression Female Nptf Adapter

Product Overview & Machining Capabilities

As a verified China factory, Xiamen Dazao Machinery manufactures custom Brass Compression Fittings engineered for high-pressure fluid and gas transfer. Our multi-axis CNC Swiss-type lathes produce precise ferrule-type sealing components that enable mechanical assembly without welding, facilitating flexible installation and pipeline disassembly.

Operating as a direct supplier, we utilize automated CNC milling, threading, and broaching to produce complex geometries-including the Brass Compression 90 Degree Elbow and Brass Compression Union Elbow-maintaining rigorous ±0.01mm dimensional accuracy across high-volume production batches.

Quality Control & Inspection Standards

Our facility operates strictly under ISO 9001:2015 quality management systems. Dimensional verification is executed using Coordinate Measuring Machines (CMM) and optical profile projectors. Thread integrity for every Brass Compression Male Nptf 45 Degree Elbow or adapter is validated via 100% go/no-go ring and plug gauge inspection to prevent galling and ensure leak-proof mechanical seals. We provide complete traceability documentation, including EN 10204 3.1 Material Certificates and First Article Inspection (FAI) reports prior to mass production.

FAQs

Custom machined brass compression fittings china manufacturer

01.What materials are used for custom brass compression fittings?

We primarily machine fittings from Free-Machining Brass (C36000, C3604) for standard applications, Naval Brass (C46400) for marine environments, and DZR Brass (CW602N) for plumbing systems to prevent dezincification corrosion.

02.Can you manufacture a Brass Compression Female Nptf Adapter?

Yes, we manufacture custom female NPTF adapters using multi-axis CNC turning. We control internal thread tolerances to ±0.01mm and verify compliance using calibrated NPTF plug gauges to guarantee strict sealing.

03.How does the ferrule-type sealing structure work?

The ferrule-type design uses a compression nut to wedge a brass ferrule tightly against the tube exterior and fitting body. This mechanical interference fit creates a leak-proof seal without the need for thermal welding.

04.Do you provide First Article Inspection (FAI) reports?

Yes. We generate standard FAI reports detailing CMM dimensional data, material certification, and surface finish metrics. Mass production only begins after engineering approval of the first article prototype.

05.What is the minimum order quantity (MOQ) for a custom supplier?

Our manufacturing setup supports flexible MOQs. We accept single-unit prototype orders (1-10 pieces) for validation, and scale up to automated batch production exceeding 100,000 units.

06.How long does it take to machine a Brass Compression 90 Degree Elbow?

Standard CNC rapid prototyping for 90-degree elbows requires 5 to 7 working days. For high-volume production runs involving multi-axis milling and turning, lead times average 10 to 20 working days.
