Flangeless tube end fittings do not require a flanging tool to achieve an effective seal. The nut turns on the tubing freely, eliminating the risk of cracking or unscrewing that can occur when plastic tubing is twisted during standard fitting connection.
With polypropylene nuts and CTFE bushings, these ¼-28 tube end fittings work with 1/16” OD polymeric tubing; the assembly is rated for 500 psi liq when tightened by hand.
VICI’s flangeless fittings include our patented* one-piece collapsible ferrule design that collapses as it is tightened. The collapse occurs in a very narrow area and seals with virtually no distortion of the tubing ID and no dead volume.
This pack includes 12 fittings, one with each color polypropylene nut: Blue, Black, Brown, Dark Gray, Green, Orange, Lavender/Pink, Purple, Natural, Red, White, Yellow
*U.S. Patent No. 6.575.501
Tech Tip
Use CTFE (Kel-F) bushings for soft tubing (PTFE, FEP, etc.), but use PEEK bushings for harder tubing (PEEK, Tefzel, polyurethane, etc.)
