How are valves fitted and cast iron radiators sealed ?
It is important with cast iron radiators that no caustic plumbing compounds are used on any part of the radiator, its valves or connections (this can react with the iron, breaking down the sealing gaskets in both the radiator & any O rings in your boiler or pumps). As the cast iron radiators are sand cast, it is advisable to flush out any small debris which may have come loose in transit. All radiator joints should be dry jointed, with PTFE tape wrapped or equivalent, around the valve threads for tightening. We would recommend the use of a thicker gas type PTFE tape on parallel threaded valves. If you have any further questions regarding our cast iron radiators, radiator valves or other products, please feel free to contact us either by phnoe or email & we will endeavour to answer you promptly.
