FLUID-LOK(TM) Double ferrule Tube Fittings

FLUID-LOK(TM) Double ferrule Tube Fittings are designed, manufactured, and quality controlled to be totally "interchangeable" with the Swagelok® brand of tube fittings.

FLUID-LOK® Product provide a reliable, leak-proof connection in instrumentation and process tubing systems, The double ferrule design, with the staged sequential swaging action of the ferrules during make-up, Back ferrule make a grip on tube & front ferrule work as sealing on tube, compensates for the variation in tubing materials, hardness, and thickness of the tube wall to provide leak-tight connections in an extensive range of applications.

Features

When the nut is tightened, the back ferrule is driven against the tapered rear of the front ferrule. The front ferrule is driven by force into the tapered mouth of the fitting body and creates a primary tubing seal. The back ferrule consistently grips the tube to hold the fitting and tubing firmly in place while the front ferrule forms a full -faced seal on the tapered surface of the body. In the twin-ferrule tube fitting design, the back and front ferrules move axially instead of a rotary motion. No Torque is transferred to the tubing during installation.
  • FRONT FERRULE CREATES A SEAL ON THE TUBING AND FITTING BODY.
  • NUT THREADS ARE SILVER PLATED TO ELIMINATE GALLING.
  • BACK FERRULE RADIALLY PROVIDES A GRIP ON THE TUBING.

Installation Instructions

Fluidfit Engineers Fluidfit Engineers Fluidfit Engineers
» Make sure all components have been assembled in correct order as shown above.
» Firmly insert the tubing into the fitting assembly until the tubing is fully bottomed on the shoulder inside the fittings.
» Finger tighten the nut.
» Mark the nut at position no.1 to facilitate counting the number of turns.
» When holding the body of the fitting with a wrench to prevent body from turning, tighten the nut with another wrench 1.1/4 turns to position no.2
