Customizable Threaded Connector Nut Hollow External Threaded Pipe
Product Overview

This product is a hollow full-thread external joint (also known as: hollow external thread sleeve, full-thread connecting pipe), featuring a full external thread wrapping + hollow through-structure design:

  • The outer surface is equipped with high-precision threads, allowing direct screwing into internal threaded interfaces (e.g., valves, pipe fittings, equipment bases)
  • The internal hollow channel supports fluid transmission, cable threading, or structural connection without media, enabling the integration of "connection + functional channel"
Technical Specifications
Dimension Key Parameters Technical Analysis
Material System Stainless steel 304/316 (primary choice), carbon steel (zinc-plated)
  • 304/316: Resistant to acids, alkalis, and salt spray (salt spray test ≥100 hours), suitable for food, chemical, and marine applications
  • Zinc-plated carbon steel: Cost-effective, ideal for dry environments (salt spray test ≥48 hours)
Thread Specifications Pipe threads (G1/8"-G2", NPT1/4"-NPT1"), metric threads (M8-M36)
  • Pipe threads: G is a parallel pipe thread (requires a sealant); NPT is a tapered pipe thread (self-sealing, suitable for high pressure)
  • Metric threads: Designed for mechanical structural connections, with a thread tolerance class of 6g
Custom Dimensions Length: L=10-100mm (standard: 15/20/25mm); outer diameter: D matches the thread; inner diameter: d=D-2*wall thickness (wall thickness: 2-5mm) The hollow inner diameter can be customized (e.g., larger diameters for cable threading), and the wall thickness ensures tensile strength (≥200MPa)
Surface Treatment Stainless steel mirror polishing (Ra≤1.6μm), blue-white zinc/plated color zinc for carbon steel Enhances corrosion resistance and aesthetics. Stainless steel can be customized with passivation, nickel plating, or other special treatments
Application Scenarios
Fluid Engineering
  • Plumbing systems: Connects faucets and angle valves (G thread + PTFE tape to prevent leakage)
  • Industrial pipelines: Transmits chemical fluids (316 stainless steel) and beverages (304 stainless steel, food-grade), with the hollow structure ensuring unobstructed media flow
Mechanical Assembly
  • Structural connections: Used for machine tool bases and brackets (M thread, with hollow channels for hydraulic pipes/air hoses)
  • Vibration environments: Full-thread engagement provides strong vibration resistance, replacing welding for easy disassembly and maintenance
Electrical Wiring
  • Cable threading sleeves: The hollow channel routes cables, while external threads secure the component to equipment enclosures (e.g., control cabinets, sensor bases), integrating connection and wiring functions
Key Advantages
  • Dual-function of "connection + channel": Unlike traditional external threads (which only connect), this product's hollow design enables simultaneous media/cable transmission, reducing system complexity
  • Precision thread guarantee: Utilizes a thread-rolling process for full, uniform thread profiles and strict tolerances (100% inspection with go/no-go gauges), ensuring compatibility with both imported and domestic internal threaded components
  • Multi-scenario adaptability: Supports dual systems (pipe threads for fluids, metric threads for structures) and materials (stainless steel/carbon steel), meeting needs from civil applications (plumbing) to industrial settings (chemical engineering)
