ELRING "Curil T" Tube à 75 g, non-hardening heat-resistant sealant, resistant to water, oil, grease, gas and air (Automotive)
Curil T was recommended to me for sealing Simson cylinders. But I have it lubricated to exhaust connections. Without faults and as expected. Does not harden and man can at disassemble again unregistering well. Excellent! Many thanks. Meets function.
