He suggests using silicone on the thread.

While it can work it is NOT the best to use by any means..

Use a proper non-hardening thread sealant intended for pvc threaded connections and be done with it.. Its easy to find and there is no valid reason to not use it if you have the chance..

Silicone will not reform well once set if its disturbed/taken beyond its strain point.. A thread sealant will as its non-hardening..
