Introduction
Welch Materials announces a new line of Stainless Steel Fittings engineered for the demands of modern high-performance liquid chromatography. Designed and manufactured to the exacting standards chromatographers expect, these fittings deliver rapid, tool-free installation, exceptional sealing reliability, and broad compatibility across analytical and ghost-catching column platforms.
Key Advantages
- Tool-free installation: Ergonomic, hand-tight design enables rapid connection and disconnection without tools, reducing setup time and simplifying routine maintenance and column changes.
- Superior sealing performance: The PEEK ferrule is engineered to deform predictably, forming a tight, leak-free seal against the mating surface to protect system integrity and sample integrity.
- Wide system compatibility: Standard 10-32 screw thread matches the majority of analytical and ghost-catching columns, making these fittings an ideal, low-risk replacement or spare for multi-vendor laboratories.
Technical Overview
- Thread: 10-32 screw thread
- Ferrule material: PEEK
- Housing material: Stainless steel
- Installation: Hand-tight
