These John Guest NPT Push Fit Connectors are manufactured from a non-toxic Acetal copolymer which meets both WRAS and FDA requirements. Utilising NPTF threads each connector is designed to be leak-proof without requiring PTFE tape, whilst maintaining compatibility with standard NPT threads. A metal-free construction means these fittings offer excellent chemical compatibility, which makes them suitable for a number of other water treatment applications (including RO and DI water). Complete with integrated seals for a quick and easy leak-free connection.

Please note we are able to supply a range of John Guest connectors and adaptors not listed on our website. For customers looking for a particular connection do not hesitate to get in touch with a member of our team.

Lovely company to deal with and prompt delivery. I'm in the scottish highlands and they recognised that post is better than courier for rural deliveries.
A wide range of filters ( and UV bulbs) available. Extremely prompt delivery at a very competitive price. Great follow up customer care too.

I bought the wound sediment filters. I found the filters arrived very quickly. It was later followed by a courtesy call to make sure the product was received and correct. Just fitted the filter and it is working very well. Very friendly customer service, would not hesitate to reorder from them in the future.
