An aerobic threadsealant only cures in absence of air and presence of metal, hence any extra material that gets squeeze out from the threads and remains exposed to air will not cure. It does not mean that product between the threads has also not cured.
Use of Threadsealants on less active surfaces such a stainless steel, anodized aluminium,titanium or other passivated surfaces is very common. However,Anaerobicthreadsealants tend to cure slowly on these surface and use of Loxeal Primer-11 over passive surface can speed up the adhesive curing and is strongly recommended.
However prior testing should be conducted because anaerobic Primers can reduce the final locking strength.
Apply a bead of threadsealant on the thread next to leading thread in circular fashion so that entire circumference is covered. Further assemble the fittings as usual.
Typically Loxeal threadsealants can withstand pressure of more than 500bars.
Loxeal 58-11 and Loxeal 85-86 are formulated for use in Oxygen line and are BAM approved product. No other product should be used on pure oxygen line.
Anaerobic liquid threadsealants are recommended to be used on metal to metal joints only. For applications on plastic fittings, please refer to our plastic threadsealant range.
Some users for fear of leakage, use PTFE tape along with threadsealants. It is strongly NOT recommended because not only it does not provide any added benefit, it will lead to improper curing of the sealant and doubles up the cost. Loxeal threadsealant when selected right for an application will provide optimum sealing under all circumstances.No other additional sealing mechanism is required.
Anaerobic threadsealant are fast curing products designed to withstand pressure in short span of time. Yet, if you have applications where very high pressure is applied to assembly in very short time period, then Loxeal Activator-11 can be used to speed up the curing of Threadsealant. Alternatively heat curing can be done to speed up cure and increase strength through cross linking.
Most anaerobic threadsealant joints can be dismantled using standard hand tools, but if a thread joint is too large, typically > 2.5″ or if a high strength threadsealant is used, dismantling can be challenging. The only method in such cases are to heat the parts above 250°C and open while still hot.
Loxeal anaerobic threadsealants are resistant to a very wide range of industrial fluids and chemicals without any noticeable loss in product properties, yet if customer is not sure it is best to run a preliminary test to validate. Alternately you can contact us for more details.
