Rated 4 out of 5 by from Thread compound We have struggled to seal joints from our petrol tank in our Motor Glider. LA-CO sealed it first go, very very pleased

Rated 5 out of 5 by from Job saver This stuff is brilliant. Has made my plumbing water tight every time I’ve used it.

Rated 5 out of 5 by from Instant sealing! This compound is easy to apply and needs no curing time. Acts a lubricant when assembling and wipes clean. It maintains a good seal with compressed air unions tested up to 10 bar. Much better than teflon tape. Highly recommended.

Rated 5 out of 5 by from For serious pipework! Very similar to the US Black Swan product, which we used until this came along. First class for a wide range of pipework, though it needs to be used in conjunction with PTFE tape or thread for really large threads. Built-in brush is handy. Slight overkill for domestic plumbing, but works well on any threaded pipe fittings, especially malleable iron.

Rated 5 out of 5 by from It really works. We have used it on Speedfit, Galvanised threaded, plastic threaded, copper to Stainless threaded and after a month we have not had any leaks AT ALL. Also because it lubricates the thread it makes tightening less effort. Not cheap but worth it.

Rated 5 out of 5 by from Very useful for small DIY jobs As a plumbing hobbyist this very useful for those small jobs in the house. Much cheaper than calling a plumber.

Rated 1 out of 5 by from Didn't work Applied to mains pressure shower connection, male threads as in instructions....... Water on... Leaking both hot & cold connections. Dismantled cleaned, 6 laps of PTFE tape... All good. Don't know if I did something wrong but it quite simply didn't work
