FAQs
Do I still need sealing tape with the Jubilee Clip version?

Can they be used with different pipe materials?
Yes, Pennine Top Hats are compatible with most standard 110mm and 160mm plastic pipes.
Are they reusable?
They are designed as permanent fittings, but can be cut away and replaced if necessary.
