A Clean Square Cut...
The key to obtaining a leak-tight seal in a Press-Tight® connector—or in other connecting devices that
make a compression seal with the end of the column—is a clean, right angle cut at the end of the column.
If you use an unsuitable device to cut your columns, you run the risk of angled cuts or chipped or jagged
edges that will not seal effectively, or even crushing the end of the column. We offer a selection of scoring
tools that will help you properly cut your columns.
ScoringWafer with Handle
• Ceramic wafer is serrated on one side and straight-edged on the other to cut both fused silica and
metal tubing cleanly.
• Unique, ergonomic handle is made of soft, comfortable rubber.
Make clean, square cuts!

Hold tubing firmly in one
hand, allowing about two
inches to extend freely. Hold
the scoring wafer at a 45°
angle to the tubing. Exert just
enough pressure to put a
slight arc in the tubing. Pull
perpendicularly across the
tubing.
The tubing
should fall off
on its own, or it
should easily
break at the
score with a
slight tap of the
wafer.
Check the cut
against the
white of the
scoring wafer.
Look for a
clean, square
cut.
Make a clean, square cut
for optimum perform-
ance. The cut on the right
will produce a poor seal.
