Product Performance and Features
The product has graphite material as main material, and does not pollute copper fluid. Preliminary heating is not necessary (dry it after being damped). Use it after installation. It is not easy to oxidize, burst , and can be used repeatedly. The product has overcome not only the easy oxidation shortcoming of ordinary graphite protective sleeves, but also the shortcomings of carborundum protective sleeves, such as pre-heating required and easy to burst.
