K-FLEX 1-1/2" x 6 ft. Pipe Insulation, 3/4" Wall

Most domestic hot water boilers use 1 1/2" pipes on feed and discharge side of unit. You paid to heat the water so you should insulate these 2 pipes to get the heat where you need it, not in air around boiler. There is a video at vendor's site that shows exact dimensions and this IS for 1 1/2" diameter black iron pipe. The 6' length covered my pipes thoroughly with none left over. Nice product with glued seem AND additional tape for seam-over. You won't find this at LOWES or HOME DESPOT. Seems to be a professional insulators product and it works perfectly. Pays for itself quickly as a lot of heat will be lost around un-insulated pipes. Comes in a nice 6' long box, packaged well.

Couldn’t find this size at my local store. Worked perfectly on my outdoor pipes.

After one year in Michigan weather still looks like when first installed.

Excellent quality and better than expected. Foam was one piece not rolled up. Excellent 2 way strong sealing system. Best I have seen -worked great for insulating water pipe inside basement from condensation.

Expensive but does the job. Easy to work with. Protects well.

Good

I purchased this product to wrap the pipes of our irrigation system. My husband says this is durable and the "sticky" tape is strong. I'm assuming this will hold up thru the winter. Fingers crossed.

Easy to install. Sufficient insulation to help efficiency of unit. I think anyone could do it.
