1/4-28 and M6 fat bottom fttings for 1/32” or 1/16” OD tubing
Fitting system designed to not loosen during vibration
With thebeneftsmentionedon thepreviouspage, theSuper Flangeless
Fittings for 1/4-28 or M6 fat bottom ports are quickly becoming the
standard for instrumentation, displacingmany fanged tube assemblies.

change in performance or damage to the tubing. Find a variety of nut
styles and materials on this page, plus contact your local distributor
