AMFLO Fluid Systems & Components

Ultra High Purity (UHP) fittings are precision-engineered connectors designed for reliable and contamination-free integration of regulators, valves, and gas distribution systems. They are essential in semiconductor, pharmaceutical, chemical, and analytical applications where leak-tight and particle-free gas delivery is critical.

Key Features:

Ultra High Purity Construction

• Manufactured from electropolished 316L stainless steel to minimize particle generation.

• Internal surface finish Ra ≤ 0.25 μm to reduce adsorption and ensure easy cleaning.

• Designed for ultra-clean applications, often free from lubricants or elastomers.

Leak-Tight Performance

• 100% helium leak tested to ensure hermetic sealing.

• Metal-to-metal sealing technology (e.g., VCR®, VCO®, or compatible face seal designs).

• Reliable under both vacuum and high-pressure conditions.

Versatile Connection Options

• Widely used for regulator adapters, gas panel connections, and line transitions.

• Available in straight, elbow, union, and reducer types to fit different layouts.

• Compatible with orbital welding, compression, and face seal connections.

Cleanroom Assembly and Packaging

• Assembled, tested, and double-bagged in ISO Class 5 or higher cleanrooms.

• Delivered particle-free and ready for direct installation in UHP gas systems.

Safety and Standards Compliance

• Designed to meet SEMI and international standards for UHP systems.

• Suitable for inert, reactive, and specialty gases used in critical processes.

Applications:

• Regulator and valve adapters for UHP gas delivery systems

• Semiconductor manufacturing (CVD, ALD, etching, lithography)

• High-purity chemical and pharmaceutical processing

• Analytical instrumentation and laboratory research gas lines

Ultra High Pressure (UHP) diaphragm valves are precision-engineered to control and isolate gas or liquid flow in ultra-high-pressure systems. They are widely used in semiconductor, chemical, pharmaceutical, and analytical industries where contamination-free and leak-tight performance is essential.

Key Features:

Ultra High Purity Construction

• Electropolished 316L stainless steel with internal surfaces polished to Ra ≤ 0.25 μm.

• Metal-to-metal or elastomer-free designs to prevent contamination.

Leak-Tight Performance

• 100% helium leak-tested for hermetic sealing.

• Suitable for UHP gases, corrosive gases, and high-purity liquids.

High Pressure Capability

• Reliable operation up to several thousand psi.

• Stable, precise flow control even under extreme pressure conditions.

Actuation Options

• Manual, pneumatic, or electric actuation available.

• Fast response for automated systems.

Cleanroom Assembly

• Assembled, tested, and packaged in ISO Class 5+ cleanrooms.

• Optional pre-conditioning or flushing with inert gases.

Safety and Compliance

• Meets stringent safety standards for high-pressure applications.

• Certified for use with hazardous or reactive gases, depending on model and certification.

Applications:

• Semiconductor fabrication (CVD, etching, lithography)

• High-purity chemical and pharmaceutical systems

• Analytical instrumentation

• Aerospace, research, and laboratory high-pressure systems
