Specification:
1. Product Overview
The PCF series 304 stainless steel pneumatic quick-connect fittings feature an all-stainless steel internal thread + pneumatic tube quick-connect integrated design, including specifications such as PCF6-01 (G1/8‘), PCF8-02 (G1/4’), PCF10-03 (G3/8"), etc. These connectors are specifically designed for corrosive environments, food and medical applications, and high-cleanliness scenarios, combining military-grade sealing performance with an exceptionally long service life.
2. Core Parameters
Item Technical Specifications
Material 304 stainless steel (mirror-polished surface with Ra ≤ 0.8 μm)
Pressure Range Vacuum to 1.6 MPa (burst pressure ≥5.0 MPa)
Temperature Resistance -40°C to +200°C (short-term 250°C)
Compatible Tubing PU/silicone
Connection Standard Threaded end: G thread (ISO 228-1)
Surface Treatment Electrolytic Polishing (EP) or Passivation Treatment (optional)
3. Core Advantages
✅ Superior Corrosion Resistance: Passes 96-hour salt spray test (ASTM B117), resistant to acids, alkalis, and organic solvents
✅ Zero Contamination: Mirror polishing (Ra ≤ 0.8 μm) eliminates bacterial residue, meeting GMP cleanroom standards
✅ Quick-release design: Patented dual-latch structure (Patent No. CN202320584U), insertion/removal force ≤ 30N
✅ High flow rate: Straight-through flow channel design (pressure drop < 0.015MPa@1.0MPa)
4. Selection Comparison Table
Model Outer diameter of air tube Thread specification Torque value Typical application
PCF6-01 6±0.1mm G1/8" 10-12 Nm Pharmaceutical equipment/laboratory reactors
PCF8-02 8±0.1mm G1/4" 15-18 Nm Food filling machines/bioreactors
PCF10-03 10±0.2mm G3/8" 20-25 Nm Chemical pipelines/semiconductor gas transport
5. Special Process Notes
Electropolishing: Reduces surface roughness and prevents particle adhesion (suitable for cleanrooms)
Online cleaning (CIP): Supports 135°C high-pressure steam sterilisation cycles
Anti-misinsertion design: Different specifications use colour-coded rings (6 mm blue/8 mm green/10 mm red)
6. Installation specifications
Threaded seal:
Tighten to the recommended torque value to avoid overloading and intergranular corrosion
Air Tube Connection:
Must use a dedicated tube cutter (e.g., SMC TU series) to ensure perpendicularity of the cut
Clean the tube end with isopropyl alcohol before insertion
Verification Testing:
Helium mass spectrometry leak detection (≤1×10⁻⁹ Pa·m³/s)
