Cheminert low pressure fittings are ideally suited for flow injection analysis, low pressure liquid chromatography, and stream sampling devices. They may be safely used at pressures up to 500 psi and temperatures to 50°C.
Two designs of low pressure tube end fittings are available.
Flangeless tube end fittings utilize our collapsible ferrule, which grips the tubing as the fittings is tightened without significantly reducing the tube ID.
Flanged tube end fittings are retained on polymeric tubing by a flange formed with a Cheminert flanging tool.
External nuts with female 1/4-28 threads are designed for use on tubing with a flanged end, just like the flanged tube end fittings.
