Flowell F-LOCK 30 SERIES Tube Fittings Installation Guide
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.

Flowell 20/20A Series Tube Fittings Manual
The Flowell 20/20A Series tube fittings are made of fluorocarbon resin and feature a unique internal‑ring construction that ensures excellent sealing, chemical resistance and high‑temperature capability. The fittings are compatible with NPT threads ranging from 1/8" to 1" and are interchangeable with the 20 Series body and nut, while using a slightly different ring.
The manual includes product features, ordering information, dimensional tables, installation instructions, and detailed maintenance cautions. It explains the use of a Go/No‑Go gauge and a life spacer to monitor the remaining service life of the fittings and provides safety procedures for disassembly and leak checks.
