Rated 5 out of 5 by from Flomasta external leak sealer Does what it’s suppose to do, sealed the leak on washing machine and dishwasher pipe.

Rated 5 out of 5 by from cistern leak My bathroom toilet cistern had a slight leak where the overflow pipe is situated and rather than replacing the fittings I tried this flomasta external sealer and put it around where the leak was coming from and it fixed it. No more leak.

Rated 5 out of 5 by from Seals well as expected Used on a new leaking soil stack assembly. I took it apart to apply the sealant. I also have used on a leaking gutter joint. Can be put on external joints or used when assembling. Either way it works really well and the joint can also be taken apart if required

Rated 5 out of 5 by from Hose pipe connection Found a leak which was due to the main pipe connection thread being damaged at back of washing machine. This product did the trick to seal and avoided the expense of a plumber.

Speedfit tap connector

I would like to do a belt and bracers job on fitting a Speedfit plastic tap adapter, onto a metal tap post. It’s a very tight space…hand tightening only is possible. Would this product help? PTFE is impossible as there’s no space for wrapping around.
Asked by: Kokoshka
Hello, Thank you for your enquiry. Yes, it will certainly work as a gasket, but you may have better results if you use Flomasta Liquid PTFE. It's always difficult to advise when you can't see the restrictions you have. Thank you for using Q&A.

Will it seal a petrol tank leak.

I have a plug in a two stroke engine petrol tank and the manufaturers sealant has seteriorated and needs redoing. Is this compatible with sealing petrol?
Asked by: EdwinM
Hello, Thank you for your enquiry. The supplier has told us that this has not been tested for petrol so cannot advise. Thank you for using Q&A.

Bonding HDPE

Will this bond a rubber bung to HDPE plastic
Asked by: Westy999
The product should grab to both surfaces but if the purpose is to give a pressure seal it may not work as expected. The product is essentially a handy reusable equivalent to silicone sealant that would normally be purchased in larger volume and be dispensed from a tube with a mastic gun.

Does this work on copper pipes

I have a pinhole leak on a copper pipe in a very inaccessible area
Asked by: DIYer0
Hello, Thank you for your enquiry. What i would recommend repairing with a copper fitting because if you have a pin hole the hole will only get bigger and may burst if the pressure is increased and may cause more damage. Hope that helps. Thank you for using Q&A.

Is this suitable for use in a aquarium

Asked by: Janste1955
This is a plumbing product so using it in an aquarium is not it’s intended use. Furthermore it’s ‘acetic acid cure’ and gives off a vinegar smell as it cures. We would not recommend it for this application.
