Thread locker for SAE O-ring fittings?
Thread locker for SAE O-ring fittings?
(OP)
Is it ok to apply a few drops of Loctite 243 to the threads to help prevent loosening by vibration? Is there a better solution?
I don't want to interfere with the O-ring seal but need assurance it won't back out under vibration (RR locomotive).
TIA

RE: Thread locker for SAE O-ring fittings?
O-ring fittings are typically not subject to vibration loosening, because they are almost always mounted to hard lines or thin brackets which damp the actual vibration applied to the connection, and the o-ring itself provides a nylock-like aid to vibration loosening resistance.

no history of vibrating loose but i since it is mounted to hard piping lines which can vibrate i wanted to see if there was an "insurance factor" in the form of a thread locker / vibratite that could be added

When working with SAE products remember that they were designed for on vehicle use which includes vibration resistance. They were not designed for shadetree repair where unknown products get slathered all over the engineered system.

So, if properly torqued to spec that's all that's needed.
