Rated 1 out of 5 by from Would not cure I tried using this to seal a metal threaded valve body to a Hozelock fitting. I absolutely could not get the stuff to cure even though there were no large gaps. It’s anaerobic no I even tried coating the small bead of material that was visible at the end of the joint with epoxy but not even that helped. Very disappointing.

Rated 5 out of 5 by from Flowasta PTFE liquid Late convert to this product. New mains water pipe,plastic onto metal & plastic on plastic was weeping. Used this & instantly stopped all drips. Will definitely use again. Not a great amount of product in the bottle & probably won't last for many jobs, however, worth the expense to prevent leaks.

Rated 5 out of 5 by from What a lifesaver Having just fitted two new aluminium radiators; they both had leaks at the valves, both were well taped with PTFE tape. Overtightening was not an option with the aluminium. A friend told me about liquid PTFE. My very friendly local Screwfix had this in for me by next day. This must be a plumbers dream, it makes assembly very easy by lubricating the threads, an absolute 'doddle' to apply and a minimum of tightening necessary. Now NO LEAKS. A toolkit necessity.

Rated 5 out of 5 by from Plumber Been using liquid ptfe for years never had a problem, but the brand i use is very expensive, this on the other hand is a fraction of the price and does the same job only recently started using this product but no issues so far .my apprentice takes a couple of minutes to make up a radiator now very pleased

Thread size

What size Thread can you apply the liquid Ptfe too i.e 1' threaded male fitting for a hot water cylinder
Asked by: Nhplumber
Hello, Thank you for using Q&A. The supplier has advised: Liquid PTFE will work with any pipe size in a domestic application. It’s WRAS approved for cold and hot water use. It can fill a thread gap of up to 0.3mm - follow instructions on the pack - the back label opens up as a booklet and contains further information on usage. Hope that helps. MH

Can I use this on a steam fitting (4.5 bar max)?

Replacing steam solenoid valve on domestic steam iron.
Asked by: TheOtherGeorgeK

When can I turn the water on?

I am going to use this on the SS outflow fittings of a domestic submersible pump which supplies water for the house. The pump is 3 bar. The temp is 20deg. Do I have to wait 72 hours before turning on the pump? (Which would be difficult) Thanks.
Asked by: Gjh29
Stainless Steel takes 72 hours to fully cure. The percentage cure versus time is non-linear. 70% pressurisation is achieved after 24 hours.

has flowmasta liquid ptfe got a shelf life

Asked by: shedlen
Yes the shelf like is 36 months and there is an expiry date on the product - which is of course based on the product remaining unopened. If the product has been opened and used this period will reduce.
