Catalog Number - 49225-04-C

49225-04-C ARE‑Applied Research PTFE Tubing is a large‑bore, high‑capacity fluid transfer solution engineered for HPLC, UHPLC, LC‑MS, and general laboratory applications, providing an extra‑large internal diameter for maximum solvent throughput with minimal restriction, combined with a long continuous spool for efficient system routing.

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

Supplied on a convenient 25 meter spool, making it ideal for bulk laboratory use, custom installation, and OEM integration.

Precision Dimensions – Extreme Flow Capacity

• Inner Diameter (ID): 0.19" (4.75 mm)

• Outer Diameter (OD): 1/4" (6.4 mm)

• Wall Thickness: 1.65 mm

• Tolerance (ID & OD): ± 0.20 mm

✅ Extra‑large bore enables maximum flow rates for high‑volume fluid movement
