Customer Reviews for Nashua Tape 1.89 in. x 50 yd. 322 Multi-Purpose HVAC Foil Sealer Duct Tape

Wow! Tape worked great. Cold air was leaking from my A/C duct work which made the A/C overwork and keep freezing up, particularly on the hottest days. I use the tape to stop the air leaks and the A/C is working more efficiently and - no freeze ups!

I used it to seal my air conditioners into the windows and it worked great. Love it‼? I will buy again in the future ‼?

Stayed and glued on vent pipe very well

Too expensive. It did the job but should have cost less

I just bought this tape. I didn't see the UL 723 designation on mine.

good tape i used it for AC vents/ tubing / cabinet sealing

I used this for all sorts of stuff.

Very sticky! Used for sealing seams with fiberglass batt insulation and it did the job very well. A little difficult to unroll and cut/tear, especially when wearing rubber gloves because you have to manage the paper-like layer necessary to keep the tape from sticking to itself.

Have used Nashua tape in the past. Tried off brand tape and had to return because it simply was not Nashua quality, or at least the Nashua quality I was used to. Disappointed in the tape Nashua is selling now. Backing material overran on the side of the roll making it difficult to pull the tape once I was able to get the tape loose from the backing. The backing exposed on the top maybe 2' of the roll simply did not want to release the tape. Frustrating is an understatement. I expect far more from Nashua for the price as it is 2 or more times the price of off brand tape. The first few feet of tape seem to need to be discarded as after that the tape did adhere well.

Used to affix insulation to the firewall of my airplane. Holds well.

Great product to use. Highly recommend.

Fantastic aluminum tape
