Dave T –
Used this to fix a small leak on a 16mm pipe in our underfloor heating loop – worked perfectly. The compression seal is tight, and I had no issues with fitting it even in a tight space. It feels solid and well-machined, and it saved me the cost of replacing a whole section of pipe. Great value for money and ideal for emergency repairs. Will definitely keep a couple of these on standby from now on.
