Loctite 55 Pipe Sealing Thread Cord for Water and Gas Leak Fix - Size 150m

One is Loctite 55; the other is regular plumbers tape I twisted up. I usually spend time trying to not twist my plumbers tape. The biggest difference is that the Loctite 55 comes out a bit flat, so you cant twist the regular stuff too tightly if you want to match the Loctite 55. I tried the Loctite 55 on a new faucet I am installing, and it did not go well at all. It is really hard to get it just into the threads, but if you dont you cant tighten the bolt; it jams. I ended up removing the Loctite 55 and using regular plumbers tape. BTW, the Loctite 55 is on the right in the photo.

Works well with British style (straight, not tapered) pipe fittings.

I purchased an OVE bidet from Canada which has an anti-hammer valve at the wall and the threads were too long which made the valve bottom out into the new brass wall fitting I installed. I could not grind off the end as part of the mechanism is flush with the end of the valve. I tried two types of sealant as well as Teflon tape and could not seal it. I was using a 16” pipe wrench and tightened it so much I was afraid I would break the screws off the brass fitting inside the wall. I finally was able to seal it with pipe dope made for gas lines, however the valve orientation was wrong (outlet heading down but it should be up) and I was not sure the pipe dope would last in water service. I knew about the Loctite 55 but it is so expensive, well I purchased and applied the Loctite 55 it sealed right away. I only had to tighten it half as much as I tried to before, I was able to orientate the valve to the proper position which I could not do before. This stuff is terrific; my only complaint is you have to buy so much of it. Come on Loctite make some half and quarter amounts available.

seals better then teflon tape and allows for some re-positioning without leaking
