FluoroLine PFA tubing pressure ratings were established using ASTM D2837. This test exposes the tubing to long-term, constant pressures at various temperature settings. Our test took 22 months to complete. From the analysis, a hydrostatic design basis (HDB) value is multiplied by a safety design factor to obtain a hydrostatic design stress. The HDB value is used to determine the tubing operating parameters. FluoroLine PFA tubing completed this extensive testing.
All FluoroLine tubing products are fully characterized and all performance ratings are derived from quantifiable data. Our design and process expertise allow you to confidently design your fluid systems reliably and safely.
Pressure Loss vs. Flow
(Reference the 5th, 6th and 7th charts) This data is for water (fluid with s.g. = 1.0). For pressure loss vs. flow capability outside of these calculations, please contact Entegris.

Maximum Pressure Rating Chart
FluoroLine Ultrapure PFA Tubing
Maximum pressure capabilities of various sizes are listed below. (Flaretek nut ratings are included as a reference.) These ratings are provided as a guide in system design. The component with the lowest maximum pressure rating determines your system maximum pressure rating.
