## Customer Reviews

### ⭐⭐⭐⭐⭐ Selfseal outdoor pipe
*by C***D on 16 February 2026*

Great product very easy to use as it just sticks together around the pipe

### ⭐⭐⭐⭐⭐ Quality
*by P***L on 1 August 2025*

It's armaflex

### ⭐⭐⭐⭐⭐ Important boiler pipe protector
*by A***R on 25 January 2025*

Very good protection for outside boiler condensate pipe to prevent freezing on winter. If this pipe freezes, it stops boiler from working, so definitely work applying to reduce risk, as it's nice and thick.
