This is an insulated wrap that is sticky on one side, so it should stick to the plastic tubing. I have wrapped pvc and copper pipes with it and neither have ever froze with this on them.
If the pipe is DRIPPING due to condensation, yes. Thats what I used it for in my basement so my gym equipment wouldnt rust! If you mean theres a split or a bad seal in a pipe and its physically leaking, than no you have to seal the leak.
The adherence strength of this tape is not very strong. Also If the glycol is cold, I fear that Your seal would not be dependable enough to prevent pipe sweating, which would more than likely destroy the adherence. I used the tape to insulate the exterior of an egg incubator molded plastic construction operating at 100 degrees, with no concern for moisture or sweating. Your insulation mfgr. should be able to recommend a suitable product. PS: If you can get the butts tight enough, You might have success with aluminum duct sealing tape which offers a very strong bond to smooth non porous surfaces. H.D. sells that also. Good luck !!!!!!!!!
This is not heat resistant. Heat resistant tape will NOT have any foam (etc). Just ask you Home Depot employee for help finding heat resistant tape. It costs more...
No
I was able to wrap 5-1/2 feet of 2 inch pipe with approximately 1/2 inch overlap - 1-1/2 inch exposed.
I live in south Texas and have used it only as low as 28 degrees.
I went right up to it.It has held HOT temps as well as COLD temps.Very good Tape.I would say NON combustable
As long as they are bone dry to start out with.
I do not know. Call an HVAC company to inqire...ask if insulation can be protected with some type of material. Or, replace the foam tube insulation.
