Rated 4 out of 5 by from Plastic to metal non- tapered Needed to be used additionally with ptfe tape in order to stop a weep on a plastic to metal thread connection. PTFE alone left a weep, this compound alone left a weep, only by using both options together worked on the joint I had to seal. May be just not ideal parts I had to use supplied by the meter guys ( not screwfix ) but personally I wouldn't use on its own unless was tapered thread or additional seal. Applied a lot and mixed it well. Thread was at least 20mm woukd have thought more than enough. Joint ik my case was MDPE joint onto a field water meter collar. Screwfix are totally faultless - always have what I need and close-by. Got me out of the hole - literally :)

Rated 5 out of 5 by from Good quality Wish I use this COMPOUND years ago, made my job a lot easyer as I installed 7 radiators & not one leak so far.

Rated 1 out of 5 by from Not great I thought I'll try something new and this was a mistake. Used on freshly installed new radiators, one was leaking straight away and now I've got second one dripping after month. However other 4 radiators no problems. 50/50 chance isn't good enough when now have to do one radiator again.

Potable Water

Is this suitable for use on potable water? - i.e. hot and cold water within a home? - I can see its ok for heating but to use on hot and cold water it has to be suitable for potable water which is not clear in the description.
Asked by: EvansHeating
Yes it is. I don’t know why the other answer says no because it states very clearly on the bottle “RECOMMENDED SERVICE: Potable & hot water, natural gas, ....”

Hi just wondering if this can be used on heating oil pipes?

Asked by: MpPropertyMainenance
Slic-tite Paste with PTFE is recommended by the manufacturer as suitable for use with Oils, Diesel and Gasoline. Please also be aware that the product is tested to achieve 10,000 PSI (680 BAR) for liquids. The sealing temperature: -46°C to 260°C (-50°F to 500°F). Slic-tite is only recommended for use with taper-taper threads, such as ANSI/ASME NPT, British BS 21 type BSPT, Australian AS 1722.1. We do not recommend Slic-tite for use with parallel threads, unless using a secondary seal (e.g. O-ring).
