Hollow Full Thread External Joint 304 316 SS / Zinc Plated CS NPT/G/Metric

Product Positioning and Core Structure

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 Parameters and Performance Highlights

Application Scenarios and Value Proposition

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.

Differentiated 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).
