Product Description

NAI-LOK Stainless Steel 316L Coaxial Tubing Outer Tube OD from 1/2 to 2 1/2 Electropolished UHP Butt Weld 90 Degree Coaxial Elbow Fittings

Product Description

The NAI-LOK Ultra High Purity Coaxial Fittings are designed for semiconductor and microelectronics applications, offering precise and contamination-free fluid or gas connections. Constructed from 316L stainless steel, these fittings are suitable for ultra-high purity (UHP) systems requiring low particle generation and high corrosion resistance.

This orbital coaxial terminator elbow and equal tee configuration provides flexible connection options for UHP tubing, ensuring minimal dead volume and smooth flow in high-purity systems. Each fitting is precision-machined and electropolished to meet stringent semiconductor industry standards.

COAX Series Coaxial Fittings

The inner process tube adheres to stringent specifications for raw materials, electropolishing, cleaning, and packaging, meeting the exacting standards for cleanliness and performance in ultra-high-purity fluid systems. Simultaneously, the outer safety tube ensures secure containment and distribution of overflow fluids in the rare occurrence of a process tube leak. This dual-tube system, requiring only orbital welding, offers a straightforward installation process and seamless integration into existing systems and facilities.
Applications of UHP Coaxial Tubing:
Semiconductor Manufacturing: Ensures the purity of process gases, preventing defects in microelectronics production.
Pharmaceuticals and Biotechnology: Used in cleanrooms and sterile environments to ensure the uncontaminated transport of critical chemicals.
Chemical Processing: Provides a high-purity solution for chemical transport where contamination can compromise product quality.
Gas Delivery Systems: Ideal for delivering high-purity gases in research labs and high-tech manufacturing facilities.
