Oversized Fitting Assembly (updated 3/2002)
Subject: BarbLock®™ Retainer # 135125
The 125 Series retainer
demonstrates the same dynamic retention and seal as the other series in the BarbLock®
inventory. A recent tech visit with a customer required a technique different
from the standard retainer closure. The customer was using 1/8” x 1/4”
silicone tubing and a 5/32” single tier barbed fitting with a stem diameter
of .200 dia. and a barb ridge diameter of .230 dia. The customer required a larger
fitting because of the restricted flow offered by smaller barbed fittings.
The technique as follows: - The
BarbLock® Sleeve then the Collet is placed onto the tubing (Standard).
- The
silicone tubing is pushed onto the barbed fitting in the normal fashion.
- The
tubing is stopped 1mm from the normal termination point
(For reference: the
BarbLock tool’s jaw shelf if 1mm thick) - The Collet is moved to
the base of the tubing
- The Sleeve is moved to the top of the Collet
- The
1/8” Tool is used to engage the Sleeve & Collet
- The
tool is not used to close the assembly with one motion
- When the
Sleeve has traveled one quarter of the way over the Collet the process is stopped.
- The pressure is taken off the tool handles and the assembly is rotated
90 degrees in the jaws.
- Pressure is once again exerted to the tool to
close the assembly approximately 1/16” of travel.
- Step 9. and 10.
are repeated until the Sleeve and Collet are fully engaged.
- If problems
with the assembly persist use a small amount of IPA on the outside of the Collet
prior to assembly.
