Built-in guide, to prevent cross-threading.
The inlet seal at the base of a
split/splitless injector forms a
seal between the injection port
and the inlet liner. This inlet
seal wears over time and may
become scratched or pitted,
which compromises the seal-
ing ability of the injector. Use
the Restek injection port
repair tool to easily resurface
the inlet seal and remove con-
taminants; it saves time and
money by preventing leaks.

✔
Four scoring edges for cutting fused silica tubing, four
serrated edges for cutting MXT
®
metal capillary columns.
✔
Sure-grip handle included.
Due to constant installation,
removal, and exposure to
extreme temperature changes,
threads on GC parts become
worn and damaged. This can
cause a poor seal, and oxygen
can enter the system, compro-
mising analytical results and
possibly destroying expensive
analytical columns.
Screw the rethreading tool
completely onto the injection
port in a clockwise direction.
Unscrew the rethreading
tool and inspect the threads.
Repeat as necessary.
✔
Resurfaces critical inlet seal areas.
