Catalog Number - 49225-3.7-3M

49225-3.7-3M ARE‑Applied Research PTFE Tubing is a thin‑walled, ultra high‑capacity fluid transfer solution engineered for HPLC, UHPLC, LC‑MS, and general laboratory applications, delivering an extra‑large internal diameter for maximum solvent flow with minimal restriction, combined with a moderate length for flexible installation and routing.

Manufactured from 100% virgin PTFE resin, this tubing contains no additives or plasticizers, ensuring maximum chemical purity and compatibility with sensitive analytical workflows.

Precision Dimensions – Maximum Flow Capacity
