Better than tape!
If you thinking about buying this, because you need to seal some pipe connectors just stop and do it. I found that is much better than tape or all sealants in gel.

Nice Sealing product.
It is more comfortable to use then the linen fibers, but the sealing qulity is not perfect,I tried it on plastic thread which is dificalt to seal. A combination of linen and teflon did better job. On iron or brass it shuld do better job.

Quality product
Follow the instructions and it works first time. Better than normal thin/stretchy PTFE plumbers tape.

Works well on larger threads
Works better than tape on larger threads I,e 1' and up especially on stainless steel just remember to wrap the thread in the correct direction and at start and end of the wrap a couple of diagonal wraps across the threads makes a real difference

Producto muy recomendable
Es el mejor teflón de hilo que he usado, la verdad es que con el , con poco que agarre la pieza deja de perder. Muy aconsejable para su uso en las ñapas de casa, ya que como sella tan bien, aunque no seas profesional es difícil que tengas perdidas.

No more micro leaks
This thread sealant saved me from demolishing 😤😡 the whole laundry. I tried every colored teflon tape still nothing until Loctite 55 saved the day. Definitely recommend even if it’s a bit pricey. Thank u #Loctite
