Comer Backnuts are WRAS approved, made from the highest quality PVC (unplasticised polyvinyl chloride) and manufactured in Italy to European standards. Our fittings are widely used throughout the United Kingdom.
We stock both metric and inch variants which are available in sizes: 3/8” – 4”.
Backnuts can be used to create a seal against a tank wall and in other situations where there is a need to create a seal or tighter connection.
