FlushNut™ SealTight™ Fittings Guide

FlushNut™ SealTight™ Fitting

  1. Slide the FlushNut™ and SealTight™ Ferrule, in that order, over your tubing, ensuring at least 3/16" of your flat-cut, burr-free tubing extends past the assembly. (See image)
  2. Insert the assembly into the receiving port. Hold the tubing to the bottom of the port while finger tightening the Nut into place.
  3. Please Note: IDEX Health & Science highly recommends using the FlushNut Wrench for installing and removing FlushNuts. Using the FlushNut Wrench and while continuing to hold the tubing down into the receiving port, tighten until the Ferrule is completely seated.
