This CNC Custom Brass Plug is a precision non-standard threaded pipe fitting screw, professionally machined via CNC turning process. Made from high-quality solid brass material, this custom threaded plug features stable structure, smooth surface, and precise thread matching. It is widely used for port sealing, pipeline blocking, and hole plugging in pneumatic systems, hydraulic equipment, mechanical pipelines, and electronic hardware assemblies. Tailorable for non-standard sizes and structural requirements, it meets diverse personalized installation and sealing demands for industrial equipment.
All brass plugs are processed by integrated CNC precision turning and milling. Strict dimensional tolerance control ensures uniform overall size, flat end face, and regular outline. The finished parts feature good interchangeability for batch assembly, with no size deviation affecting installation accuracy, suitable for customized precision equipment matching.
Thread parts are finely machined with complete tooth profile and uniform pitch. Each piece is inspected to ensure smooth screwing and fitting. No thread jamming, burrs, or mismatched clearance occurs. The threaded structure fits well with matched pipe holes and fittings, providing stable assembly and sealing effects for long-term static use.
Made of qualified industrial brass raw material, the plug owns stable physical properties, good oxidation resistance, and excellent corrosion resistance. It adapts to conventional indoor, humid, and light industrial working environments, not easy to rust or deform. Meanwhile, brass material delivers good ductility and machinability for various customized structural processing.
After fine finishing and edge deburring, the thread inlet, outer circle, and end face have no sharp flash or rough edges. The smooth surface will not scratch pipeline inner walls, sealing rings, and matching parts during installation, protecting the integrity of the whole equipment assembly structure.
- Pneumatic and hydraulic pipeline port sealing and blocking
- Mechanical equipment reserved hole plugging and closing
- Electronic hardware and precision instrument assembly fitting
- Industrial automation equipment customized pipe fittings
- Non-standard mechanical structural sealing accessories
- Problem 1: Standard plugs cannot meet special hole size and structural demands
Solution: Support full non-standard customization in size, thread type, and appearance structure to fit special equipment installation. - Problem 2: Rough thread causes poor fitting and unstable sealing
Solution: Precision CNC thread processing and manual inspection ensure tight and smooth matching performance. - Problem 3: Ordinary metal plugs rust easily and affect equipment use
Solution: Brass material features natural anti-oxidation performance for stable long-term service.
