Shanghai Quanbao Electronic Materials Technology, based in Shanghai, China, specializes in precision-engineered components for critical gas handling applications. Our 316L Stainless Steel VCR Male Tee Fitting is meticulously crafted for ultra-high purity gas systems where contamination control is paramount. With decades of manufacturing expertise, we deliver fittings that ensure leak-proof integrity and exceptional corrosion resistance in semiconductor, pharmaceutical, and laboratory environments.
This tee fitting features:
Triple-secure connection with VCR metal gasket technology
Electropolished surfaces (Ra≤0.25μm) minimizing particle entrapment
Full 316L stainless steel construction for maximum chemical resistance
Zero dead volume design preventing gas pooling
Precision-machined threads ensuring consistent torque performance
Technical specifications:
| Parameter | Value |
|---|---|
| Material Composition | C≤0.03%, Cr 16-18%, Ni 10-14%, Mo 2-3% |
| Surface Roughness | ≤0.25μm Ra (after electropolish) |
| Helium Leak Rate | -9 atm·cc/sec He |
| Pressure Rating | 1500 psig at 70°F (varies by size) |
Advantages for industrial users include 30% longer service life compared to standard fittings, reduced maintenance downtime, and compliance with SEMI F20 and ISO 8535-2 standards. The symmetrical flow path minimizes turbulence while the work-hardened sealing surfaces maintain integrity through repeated assembly cycles.
As an ISO-certified manufacturer with facilities in Shanghai, Quanbao maintains full traceability from raw material to finished product. Our dedicated quality control laboratory performs batch testing including bubble-point and particulate contamination analysis. With over 200 successful installations in Asian semiconductor fabs, this fitting delivers uncompromising performance where purity matters.

FAQ
Q: Why 316L instead of 304 stainless steel?
A: 316L contains molybdenum for superior chloride resistance critical in UPW systems.Q: Are gaskets included with fittings?
A: Metal gaskets are optional; specify requirements when ordering.Q: Can these handle corrosive gases like HCl?
A: Yes, when properly passivated, 316L resists most semiconductor process gases.Q: What's the lead time for custom sizes?
A: Standard sizes ship in 3 days; custom machining requires 2-3 weeks.Q: Do you provide material certifications?
A: Mill test reports with full material traceability are available.Q: How many assembly cycles do VCR fittings withstand?
A: Properly torqued connections maintain integrity through 30+ cycles.
