... "Sleeving" in this sense is not an option in my book...for two reasons..it's a Code violation,and also because PVC glue will adhere to the conductors and may compromise the insulation,..not only that,if for some "Gawd forsaken" reason you need to extract one or more of the conductors,you'd be unable to do so because the glue will have adhered to the wires and side-wall of pipe making extraction impossible..(although this example pertains more appropriately to smaller conductors run thru pipe)...
