Precision Tubing Solutions for Semiconductor Labs
Cardinal UHP offers ultra-high purity (UHP) electropolished stainless steel tubing with VCR® face seal fittings welded on each end, ideal for semiconductor R&D, gas delivery systems, and cleanroom environments.
Each length is fabricated to semiconductor industry standards, cleaned and bagged in a Class 4 cleanroom, and shipped in compact packaging — eliminating the need for orbital welding or bulky stick tubing crates.
Why Choose Pre-Welded Coiled UHP Tubing?
Compared to traditional stick tubing that ships in long crates and requires welding VCRs on-site, our solution is fully integrated and ready to install. This not only saves time and labor, but also helps ensure cleanliness and performance consistency — critical in semiconductor research and manufacturing.
Features & Benefits
- Factory-Welded VCR® Connections
Reduces the need for on-site welding and speeds up installation in gas and chemical lines. - Long, Continuous Coiled Lengths
No mid-line connections. Avoids the hassle of multiple segments of stick tubing. - Cleaned and Polished to Semiconductor Standards
Smooth ID surface finish meets cleanliness specs required for process gases. - Compact and Convenient Packaging
Ships in a small box instead of a crate, making storage and handling easier. - Reduced Leak Points
Fewer fittings and welds means less chance for contamination or system failure. - 316L Stainless Steel Construction
Compatible with high-purity gas, chemical, and analytical process requirements. - Cleanroom Packaged
Cleaned, capped, and bagged in ISO Class 4 conditions for immediate integration.
