I have a roll of Blue Monster teflon thread seal tape (I bought mine from Amazon) that I use on certain fittings and fixtures, and was double-checking that it can be used on drinking water lines. In the process, I learned that the same company makes a self-fusing compression seal tape as well, in 1″ and 2″ widths.
Blue Monster’s compression seal tape is designed to be used for stopping leaks while under pressure, which usually means emergency fixes that have to be done before or without turning off the water source. Blue Monster says their tape is ideal for emergency and long-term repairs.
Layers of the tape fuse together after application, combining into a single mass. The idea is that it’ll hold until a proper repair can be done.
This special tape can bond to any type of rigid piping, such as galvanized and cast iron pipe, copper pipe and tubing, and “all types of plastics and rubber.”
The tape is stretched as it is applied – as tight as you can pull it – and as it’s self-fusing there are no adhesives to worry about.
- Seals leaks up to 150 PSI (water, air steam)
- Effective to 500°F
- Suitable for burial without jacketing
- Can also be used on irrigation pipe
It’s available in 1″ and 2″ widths. The 1″ tape is available in a value-priced package with 3 pieces of 12″ tape, and as a 12-foot roll. The 2″ tape is available in a 12-foot roll.
Pricing: ~$15 for the 1″ x 12″ 3-piece pack, ~$36-41 for the 1″ x 12′ roll, and ~$58-60 for the 2″ x 12′ roll
Self-fusing tape has been around for a while, and you have probable even seen it on TV infommercials.
In an older post, where we asked about vehicle emergency toolbox recommendations, a reader recommended Iron Grip silicone tape, currently priced at ~$9 via Amazon for a 1″ x 10′ roll.
The Blue Monster compression seal tape seems to have mixed reviews on Amazon, but part of that could be the nature of the product. Could the variability of usage scenarios be a factor, or perhaps user error?
Blue Monster’s tape is considerably pricier than other general purpose silicone tapes on the market, but I have to wonder if or how it’s different to justify the premium price. Perhaps it’s thicker?
Blue Monster says their tape was developed for professional plumbers.
If you’ve used this, what has your experience been like? Would you use this?
