A compression style fitting that installs in seconds without tools and
provides a tight, sure, leak proof seal without clamps or adjustments.
A unique grab ring for tube retention, coupled with a Nitrile O-ring
creates a positive seal and assures good tube retention with only
hand tight assembly. Fast & Tite

Note: Provide adequate fail-safe mechanisms such as
leakage detection sensors, automatic shut-off controls
or other industry and code appropriate fail-safe devices
in the design of your water-handling appliance to protect
against personal injury and property damage. Plastic fittings
containing an o-ring have a finite life depending on the
environment, media and severity of the application. Frequent
inspections and replacement of the fitting when anomalies
are found is recommended.
Assembly Instructions
1.
Cut the tube squarely and remove any burrs.
2.
Mark from end of tube the length of insertion. If using a tube
support, insert fully into tube and then mark from end of tube
support length of insertion. (See insertion length table left)
3.
Loosen nut on fitting until three threads are visible. Fittings for
glass tubes must be disassembled and the grab ring removed.
If the fitting has been disassembled the components are to be
placed in the following order: fitting body, o-ring, spacer, grab
ring and nut. Assemble the nut until three threads are showing
on the body before inserting tube.
4.
Moisten end of the tube with water. Push the tube Straight into
fitting until it bottoms on the fitting’s shoulder. Tighten nut by
hand. Additional tightening should not be necessary, but 1/4
additional turn may be added if desired. Do not overtighten 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 mark is visible, then steps 1 thru
4
must be repeated.
Whenever a Fast & Tite
®
fitting is assembled for service or reuse
the stainless steel grab ring should be replaced for maximum
tubing retention.
