This document introduces the features and characteristics of Fluorocarbon resin Tube Fittings 20, 20A Series.
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.
