Product Description
Joining two lengths of tubing, or two different thread standards, is easy with a simple union. These unions let you extend lines or adapt between connections in low-pressure chromatography systems without replacing existing tubing or hardware. They are compact, simple and easy to install.
This listing is for Kimble catalog number 420818-0000: Union, ETFE, 1/4-28. Two versions are offered: an ETFE union with 1/4-28 ports on both ends, and a PEEK union that adapts 1/4-28 to 5/16-24. Both materials offer good chemical resistance. Use matching nuts and ferrules, tighten by hand and check for leaks before running. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
