JENOLITECopper Pipe & Tank Repair Epoxy Putty Stick - Repair Leaking Hot Lines & Other Plumbing Issues - 7 inch - 4oz

I was extremely pleased with the performance of this product. It performed exactly as represented and did an excellent job for my application. I had just finished installing a kick-space heater in a hydronic (forced hot water) system. This requires cutting into the hot water feed lines and installing 2 diverter "T's" to permit plumbing to the heater (Feed line and return line). After sweating in all of the connections and turning on the water I saw - much to my annoyance - a pin hole leak - - small, but steady. If I were going to go back and re-sweat it then it would be a HUGE headache. That's when I thought I would give this product a try. After relieving the pressure in the system which stopped the leaking I brushed with a brass brush and sanded with some fine paper. Lastly, I wiped the work area with a cloth and some acetone to be sure that there were no oil contamination. I followed the direction and kneaded the piece of putty I chose to use for this repair. I immediately applied it and smoothed it out around the edges of the patch by dampening my fingers with a little water. I consider this an important step. Feather the edges where it contacts the brass or copper pipe or fitting. I let it set over night, although a shorter time would have given the same results. I just happened to do the repair in the evening. As a result, it is perfectly sealed and I saved myself a ton of work! I give this product 5 stars.

I used for crack water copper line. it is not working. water is still leaking... wasting money.. I liked to return, but I already used.. so I just left review.

A little difficult to use most o the time it wont stick and if it does it ends up falling after a while

Esto me ha sido muy útil para tapar algunas fugas de agua que he tenido en algunas de mis tuberías, en realidad han resultado en una solución fácil y rápida, nada complicada su aplicación.Si estas buscando algo para tapar alguna fuga de agua en la unión de tuberías, esto te ofrece una buena y rápida solución, no necesitas de un plomero para poder aplicarla.

This product is a waste of time and money don't buy did not work at all broke apart from pipe and leaks even when cured had to give 1star because there is no option for 0 stars

Awesome product, worked perfectly! highly recommend

Will not stick to copper if it’s wet. Does not work as described for repairing leaking copper pipe. Do not buy, get a two part liquid epoxy.

The product itself seems to work as expected, but the missing cap will result in the product drying out prematurely.
