For the pre-assembly of cutting ring fittings from 6 to 42 mm diameter.

Facilitates the assembly and disassembly of fittings, even after a long period of operation. Prevents solidifying and hardening when affected by heat, welding without pre-heating and stick-slip (jerky sliding), also in the case of high surface pressure and minor sliding movements (crawling speed).

For pre-assembly in a vice. Made of hardened tool-steel.

Flexible seal tape for rapid and clean winding on the tapered adaptor thread.
