Swagelok PFA-820-6-R1MEF0201S Union Fitting

Swagelok PFA-820-6 union tube fitting is a 1/2 in. tube-size fitting in Swagelok's PFA family, designed to connect two runs of PFA tubing with a compression-style connection. The body is molded from PFA (perfluoroalkoxy), delivering chemical compatibility for demanding fluid-service environments. This union uses Swagelok's standard tube-fitting hardware to form a leak-tight seal when used with properly prepared PFA tubing and ferrules, providing a reliable inline junction for 1/2 in. tube networks. The PFA-820-6 designation identifies the 1/2 in. tube size within the PFA union series, making it straightforward to specify for projects requiring a tube-to-tube connection rather than a threaded adapter. Suitable for installations where corrosion resistance and robust performance are required, it integrates with Swagelok PFA tubing and accessories to create durable, field-serviceable fluid paths.
