Upchurch Flangeless Nuts and Fittings

Flangeless Fittings eliminate the need to flange tubing. This removable and reusable system provides several benefits such as providing flangeless chromatography fittings for observing mixtures and solvents. Flangeless Fittings are easy to use. Just slip the nut and ferrule over the tubing and finger tighten the assembly into your receiving port. Our Flangeless Fitting require minimal downtime because component replacement is quick, taking only a few seconds. Flangeless Fittings systems typically require only one new ferrule at minimal cost when
repairing a connection.
