Shanghai Quanbao Electronic Materials Technology Co., Ltd., located in the industrial hub of Shanghai, China, specializes in precision-engineered fluid system components. Our Standard Compliant 316L Male VCR Cross Fitting represents meticulous manufacturing for critical industrial applications where reliability and contamination control are non-negotiable. Engineered to meet rigorous industry standards, this fitting ensures leak-free performance in high-purity and high-pressure environments. Trust Quanbao to deliver components that integrate seamlessly into demanding systems, enhancing operational integrity while minimizing maintenance downtime.
Core Technical Specifications & Advantages:
- Ultra-Clean Construction: Manufactured from premium 316L stainless steel with optional electropolishing (Ra ≤ 15 µin) minimizes particulate generation and adsorption, crucial for semiconductor, pharmaceutical, and high-purity gas applications.
- Robust Pressure Integrity: Designed for high-pressure service, featuring precision-machined male VCR ends with metal gasket seals (typically 316L) ensuring exceptional leak-tightness even under thermal cycling and vibration.
- Superior Corrosion Resistance: 316L's low carbon content and high molybdenum content (2-3%) provide outstanding resistance to pitting and crevice corrosion in aggressive media like chlorides, acids, and salt water.
- Precision Alignment & Flow: The cross configuration ensures accurate 90-degree branch connections with minimal flow disturbance, maintaining system efficiency and pressure consistency.
- Standard Compliance: Manufactured according to common industrial dimensional standards (e.g., SAE AS 5202 for VCR) ensuring compatibility with existing VCR-based systems and components.
Detailed Performance Parameters:

Frequently Asked Questions (FAQ):
Q1: Is this VCR cross fitting compatible with other major brands of VCR components?
A1: Yes. Our fitting adheres to the dimensional specifications outlined in SAE AS 5202, ensuring compatibility with other standard VCR gaskets, nuts, and ferrules from major manufacturers.
Q2: What is the maximum pressure this fitting can handle?
A2: The pressure rating depends on the specific size, temperature, and media. Typical ratings range up to 10,000 psig for smaller sizes at ambient temperature. Consult our datasheets or contact us for the exact rating relevant to your application conditions.
Q3: Does 'Standard Compliant' imply any specific certification?
A3: "Standard Compliant" refers primarily to dimensional conformity with widely accepted industry standards like SAE AS 5202 for VCR fittings. It does not automatically imply third-party certifications (e.g., CE, PED), which can be discussed based on project requirements.
Q4: Can I get this fitting in sizes not listed?
A4: Absolutely. While common sizes (1/4" to 1" tube OD) are readily available, Quanbao offers customization. Non-standard sizes or alternative end configurations (e.g., female VCR, tube weld) can be manufactured upon request.
Q5: Why choose 316L over standard 316 stainless steel?
A5: 316L has a lower maximum carbon content (0.03% max vs. 0.08% max for 316). This significantly reduces the risk of sensitization (chromium carbide precipitation) during welding or high-temperature service, greatly enhancing corrosion resistance, especially in welded assemblies or corrosive environments.
Q6: Is electropolishing necessary, and what are its benefits?
A6: Electropolishing is highly recommended for ultra-high purity (UHP) applications (e.g., semiconductor, pharmaceutical). It provides a smoother surface (reducing Ra), removes embedded contaminants, and passivates the surface, further improving corrosion resistance and minimizing particle shedding.
Q7: What is the lead time for standard and custom orders?
A7: Standard sizes and configurations typically have shorter lead times. For exact lead times on standard stock or to discuss timelines for custom orders, please contact our sales department with your specific needs.
Q8: How should I torque the VCR nut for a proper seal?
A8: Correct torque is critical for a leak-free metal gasket seal. Refer to the manufacturer's specifications for your specific gasket and fitting size. Generally, a controlled torque wrench should be used, following a recommended sequence (e.g., initial snug, then final torque to spec), avoiding over-tightening which can damage the gasket or fitting.
