As a specialized manufacturer in advanced fluid handling components, Shanghai Quanbao Electronic Materials Technology Co., Ltd. delivers meticulously engineered solutions for critical vacuum environments. Our Precision Machined VCR Tee Fitting exemplifies Shanghai Quanbao's commitment to reliability in demanding applications like semiconductor fabrication and analytical instrumentation. Engineered for zero-leak performance, this fitting ensures system integrity where contamination control is non-negotiable.
Crafted from premium 316 stainless steel, this VCR tee offers exceptional corrosion resistance and mechanical strength. Its metal gasket face seal design provides a permanent, helium-tight seal, eliminating the risk of outgassing – a critical advantage in ultra-high vacuum (UHV) systems. The precision machining guarantees exact dimensional accuracy, ensuring seamless compatibility with existing VCR components and reducing assembly time.
Core Advantages for Your Operations:
- Ultra-High Sealing Integrity: Achieves leak rates <1x10-9 atm·cc/sec He, meeting stringent requirements for sensitive processes.
- Superior Contamination Control: Optional electropolished finish minimizes particle generation and adhesion, crucial for cleanroom environments.
- Robust Construction: 316L stainless steel withstands aggressive chemicals, high temperatures, and repeated bake-out cycles.
- Optimized Flow Path: Precision internal geometry minimizes turbulence and pressure drop, enhancing process efficiency.
