Usage
1/Use a wire brush to clean off the rust and dirt from the repair area. Push until the impact socket’s curved part’s deepest portion (middle part) hits the leakage area. So as not to tighten the four mounting screws polarized as above, tighten it with equ
Chemical Resistance
GOOD ((except for high-octane), aqueous ammonia, A heavy oil, ethanol, ethylene glycol, caustic source oder petrol phosphorus) OK (hydrochloric acid, sulfuric acid (20% at room temperature), BC heavy oil) x (toluene, acetone MEK)
Because pipe was corroded and oil leaked, I tried to braze, but it stopped with this metal fitting.
For pipes with uneven surface, it is better for rubber to be slightly more soft.
I bought it for the first time. I did it by myself without asking a specialist. Because I am not used to it, I do not know how strong the tightening strength is, it is a difficult place whether it was too strong or weak yet. But leakage stopped, so it was good. Since the guide of the strength is written in the instruction manual, I think that it is possible to do without problem for the place that is always leaked as per instructions.
