PVC Conduit-Sealant Lubricant for expansion Joints

[maharg]

Does anybody know or recommend an easily obtainable product that would be suitable for the expansion side of a pvc expansion coupler.
Normally I have installed conduit with bends which have accommodated expansion but I have two long straight runs on my next install and although it is suggested that a sealant lubricant is used I cannot find a specific product.

Why not contact the manufacturers and have them recommend a suitable lubricating/sealant grease for their product!!

just go to any elec wholesalers and buy a can of nonsetting expansion glue
make sure u allow plenty of slack on the wires in the conduit/light fittings or whatever, maybye put some thro boxes in with slack inside

If this conduit installation is above a false ceiling, we would normally use flexible conduit accross structure expansion joints. In my view a far better solution than a slideing joint that may not slide after a few years... lol!!
