Frequently Asked Questions

Do I need any tools or solvent to install this fitting?

No—this is a push-fit fitting, so no glue or solvent cement is needed. Simply lubricate the seal (if required), push the pipes into the sockets, and the integrated rubber rings will do the rest.

Is this coupler suitable for both above and below ground use?

Yes, the coupler is made from robust PVC-U and is certified to EN1329-1 and EN1566-1, making it suitable for use in both above-ground soil systems and certain below-ground applications, depending on your installation needs.
