Precision-machined stainless steel channel-shaped suspension hanging ring connection hardware

Connector / Adapter

1. Core User Requirements

• Reliable connection, zero leakage (for air / water / oil / chemical media)
• Smooth thread engagement, no seizing, no thread slipping
• No loosening or cracking under long-term vibration, temperature variation or pressure shock
• Interchangeable and compatible with existing systems, no “fitting failure or incomplete tightening”

2. Customization
    
   (1) Thread System and Precision

• Must be specified: Metric M / British G / Tapered R/RC / NPT / UN/UNF
• Thread angle:
  • M: 60°
  • G/R: 55°
  • NPT: 60° tapered
   
• Pitch, thread height and root radius must strictly comply with standards to prevent false locking and leakage
• Tolerance class:
  • External thread: 6g
  • Internal thread: 6H
   
• Key point: Threaded products must avoid thread damage during post‑processing (heat treatment, electroplating, oxidation, cleaning, polishing, grinding, laser engraving, etc.). Technically eliminate risks in ring gauge inspection to ensure “go gauge passes, no‑go gauge stops” and guarantee interchangeability.

• Face hard seal: metal‑to‑metal, for high pressure and high temperature
• Flat face + gasket seal: commonly used, low cost, high flatness requirement
• O‑ring seal: most universal, strict requirements for groove size and compression rate
• Flare seal: widely used for copper tubes (mostly brass) and aluminum tubes
• Tapered thread seal (NPT/R): sealed by thread deformation, must be used with sealant / PTFE tape

• Concentricity: affects engagement smoothness and eccentric wear
• Perpendicularity: critical for face sealing
• Assembly clearance: excessive clearance causes wobble; insufficient clearance causes seizing

• Rust prevention: zinc plating, nickel plating, zinc‑nickel alloy plating, passivation, electrophoresis, Teflon coating
• Conductivity: tin plating, silver plating
• Wear resistance: chrome plating, nitriding
• Outdoor / humid environment: salt spray test 24h / 48h / 96h / 1000h

• Burrs are strictly prohibited in fluid / pneumatic / hydraulic systems
• Hazards of burrs: scratch seals, block flow paths, cause jamming and leakage

3. Typical Applications

• Pneumatic systems: air treatment units, cylinders, solenoid valves, air lines
• Hydraulic systems: oil pumps, hydraulic tubes, control valves, high‑pressure circuits
• Cooling / plumbing systems: mold temperature controllers, coolers, water pumps, valves
• Medical / gas: oxygen, nitrogen, vacuum systems
• Automotive: brake lines, fuel lines, transmission lines

4. Professional Material Selection

• Low‑pressure pneumatic / general water: H59/H62 brass, aluminum alloy, 304 stainless steel
• Medium‑high pressure hydraulic / oil: 45# steel, 40Cr, 304/316L
• Seawater / chemical / highly corrosive environments: 316L, duplex steel, Hastelloy
• Food, pharmaceutical / clean applications: 316L with electrolytic polishing
