Shanghai Quanbao Electronic Materials Technology Co., Ltd., based in Shanghai, China, manufactures precision-engineered VCR fittings for critical industrial applications. Our 316L stainless steel male tee fittings deliver unmatched reliability in chemical and petrochemical processing systems, where leakage prevention and material integrity are paramount. Engineered with aerospace-grade sealing technology, these components ensure zero-contamination fluid transfer while withstanding aggressive media and extreme operating conditions.
The triple-secured VCR interface features:
- Metal-on-metal sealing for absolute leak prevention
- Axial compression design eliminating thread galling
- 360° rotational alignment during installation
Technical specifications include:
| Parameter | Value |
|---|---|
| Material Composition | 316L SS (Cr 16-18%, Ni 10-14%, Mo 2-3%) |
| Pressure Tolerance | 10,000 psi @ 70°F (4,900 kPa @ 21°C) |
| Temperature Range | -425°F to 1500°F (-254°C to 815°C) |
| Surface Roughness | Ra ≤ 15 μin (0.38 μm) |
| Connection Standards | ISO 286-2, ASME B1.20.1 |
Key operational advantages for chemical processing plants:
- Resists pitting from chlorides, acids, and caustic solutions
- Eliminates particulate generation in ultra-pure systems
- Reduces maintenance frequency by 40% versus standard fittings
- Compatible with CMP, HPLC, and SCWO processes
Manufactured in Shanghai using CNC Swiss turning centers with 0.0005" precision, each fitting undergoes triple-stage quality verification including helium leak testing and spectroscopy analysis. Our vertically integrated production ensures consistent material traceability from raw alloy to finished product.

Frequently Asked Questions:
Q: What distinguishes VCR fittings from standard pipe threads?
A: VCR connections utilize metal gasket compression for ultra-high vacuum integrity (10-9 torr), unlike NPT threads which rely on thread deformation for sealing.
Q: Are these suitable for hydrogen sulfide environments?
A: Yes, 316L's molybdenum content provides exceptional resistance to sulfide stress cracking (SSC) in sour gas applications.
Q: Can I get custom port configurations?
A: We offer modified branch angles and port sizes upon request, with typical lead times of 3-5 weeks.
Q: What cleaning protocols are used?
A: Components undergo ultrasonic degreasing, passivation per ASTM A967, and nitrogen-purged packaging.
Q: Is electropolishing necessary for chemical service?
A: Highly recommended—it enhances corrosion resistance by forming a chromium-rich passive layer and reduces adhesion points.
Q: How do I specify size?
A: Specify nominal tube diameter (1/4" to 1-1/2") and thread type (e.g., 9/16-24 UNF).
