"A quick and easy way to join 2 ends of 15mm pipe together with very little fuss. They are excellent value for money and definitely any plumber or diy useful piece of kit to keep as part or their tool box. Definitely 5 stars."
"These fittings do just what you would expect - join two bits of pipe together without making a fuss about it. There is space to get a spanner on the centre of the fitting to stop the whole lot turning which value for money fittings often don't have."
