The F‑LOCK 30 SERIES tube fittings use a Taper‑Swaging seal that provides a tight, leak‑free connection by simply inserting the tube and tightening a nut. The compact, two‑piece design is made from fluorocarbon resin (PTFE) for the body and ECTFE for the nut, offering excellent chemical resistance for use in corrosive fluids, semiconductor equipment and laboratory applications.
Installation involves inserting the tube, hand‑tightening the nut, and then using a wrench to reach the specified torque. The manual lists maximum working temperature (100 °C for ECTFE nut, 80 °C for 19 mm O.D.), material details, applicable tube types (PFA, PTFE) and reference torque values to ensure reliable performance.
| Sealing system | Taper‑Swaging Seal |
|---|---|
| Body material | Compression and extrusion‑molded fluorocarbon resin (PTFE) |
| Maximum working temperature | 100 °C (ECTFE nut) / 80 °C for 19 mm O.D. |
| Applicable tube materials | PFA, PTFE fluorocarbon resin tubes |
Insert the tube into the body of the fitting, tighten the nut by hand, then finish tightening with a wrench to the specified number of turns.
Use the reference torque values provided; do not exceed 1.5 times the reference torque to avoid damaging the threads.
The fitting uses a Taper‑Swaging seal that creates a tight seal simply by inserting the tube and tightening the nut.
