Stops leaks when nothing else will.
Used this on 1/2 inch G thread non-tapered pipe fittings that didn't have a gasket face. This stuff worked like a charm with no leaks on the first try. Seems to be the modern version of hemp and pipe dope. I highly recommend this for situations where nothing else seals the leak.

BEST JOINT SEALER THAT I'VE USED!
I just reassembled a water filter system consisting of 4 filter cartridges. The 1st time I used teflon tape. The 2nd time I tried a top recommended joint compound. Both of these attempts resulted in multiple water leaks . After more research I decided to try the Loctite 55 cord, it is faster, cleaner and easier to apply and there was not a hint of a leak at any of the 11 joints in this system.

Best improved Thread Thread
This the best method to insure your threads don't leak. Used tape many years, but this new teflon thread approach to insure leakproof threads is THE BEST for gas and water. It's much easier to apply, just cross rap cross thread the teflon threads on to your fitting. It's the only way to water tight straight fittings.

One of those things you didn’t know you needed until you used it
I mean, the layers of teflon tape SHOULD get into the grooves and make a good seal, right? I’ve seen plumbers put two, three, four layers of tape on NPT fittings and STILL get leaks. “Shoulda used recktoseal” (intentionally misspelled for copyright issue avoidance). THIS works. Fills in the deep crevices of the grooves, followed by a layer of teflon tape and WOW, good seal. Using it on a my farm deep well and it’s the first time in years I haven’t felt like I needed to crank up the torque on fittings ALMOST to the breaking point to get a good seal. Cheap insurance, get some.

producto excelente para uniones roscadas de agua Aquellas uniones que aveces dan problemas de pérdidas con cinta de teflón, con este producto queda perfecto Es cierto que permite retroceder un poco para ajustar la posición sin que queden pérdidas

Si no te dedicas a la plomería(No quiero opinar por plomeros de oficio), definitivamente debes comprar este producto, la capacidad para hacer correcciones en la rosca es de gran ayuda para nosotros los DIYers(para que pagarle a un plomero, a ver! yo lo hago!). Hasta ahorita no han fugado ninguna de las conexiones que hice. Según el fabricante también se puede usar en tuberías para gas.

This stuff is good. This sticky fibrous thread (perhpas teflon) seals better than the teflon tape. Amusingly it is similar to the traditional plumbers' thread and 'safeda'! Available cheaper from other sellers with free shipping than what Amazon shows on the landing page. I unfortunately saw this only after I had already received it.

El hilo es fácil de usar, sella muy bien y permite pequeñas correcciones del enroscado sin que se cree una fuga. Aunque dice en el envase que el hilo tiene un aglutinante que puede ser irritante para los ojos y la piel, lo cierto es que no tuve ese problema.
