Argos Complete Overhaul O-Ring Kit

This kit includes every o-ring and gasket on the Argos. The Argos was originally supplied with a mixture of Buna-N (Nitrile) o-rings and teflon gaskets.

We now use silicone o-rings in all places except for the piston gaskets which are still Buna-N and continue to use teflon gaskets.

For a true to size reference of o-ring sizes please print this document at 100% scale and verify the reference inch and centimeter lines.
