How do you assemble the Parker Fast and Tite fittings?

Fast Assembly
1)      Cut the tube square and remove any burrs.
2)      Mark end of tube the length of insertion(see table)

3)      Loosen nut on fitting until three threads are visible. Fittings for glass tubes must be disassembled and the grab ring removed.
4)       Moisten end of the tube with water. Push the tube straight into the fitting until it bottoms on the fitting’s shoulder. Tighten nut by hand. Additional tightening should not be necessary, but ¼ additional turn may be added if desired. Do not over tighten nut as the threads will strip and the fitting will not function properly. A proper assembly will not show the insertion mark extending beyond the nut. If the insertion marks are visible, then steps 1 thru 4 must be repeated.
5)      When using clear vinyl tubing or urethane tubing, it is necessary to use a tube support. Disassemble the fitting and place the nut grab ring, spacer and the tube support in hat order on the tube. Locate the grab ring at the insertion mark. Seat the o-ring in the body, then proceed with step 4.

 Types of tubing that can be used are plastic, glass, and metal. These fittings can be used for low pressure and vacuum lines up to the pressure limits shown.

Ratings are based on use with copper tubing, and in all cases represents the maximum recommended working pressure of the fitting only. Working temperature (vs. temperature) of other types of tubing may limit the tube and fitting assembly to pressures lower than show above. Consult factory for recommendations on applications other than shown above.

Temperature Range:

Black Polypropylene: 0° F (-18° C) to +212° F (+93°C)

White Nylon: -40° F (-40° C) to +200° F (+93°C)

 

All ingredients in the Fast & Tite fittings Meet FDA and NSF requirements for food contact and potable water.
