M12 12mm x 3/8 Inch Flexible Tap Connector Tap Tail Monobloc

Bought a pair of these for replacement taps. One hose fits both attachment ends but the other is ever so slightly too small and won’t screw on properly. Checked all variations and it’s definitely one hose that’s too tight. I Would imagine the quality control during manufacturing isn’t very strict.

This pressure hose fit my application exactly. And the quality seems top notch. I was unable to find a 12mm tap end anywhere, Plumbing4home saved the day! And, the customer service is very good. They answered my questions about thread sizes and sent me a photo of the hose. Couldn't ask for more!

Works well, great service from plumbing4home

excellent product

Arrived in a couple of days and appear to be excellent quality. Unfortunately, they are the wrong fitting for my mixer tap and isolater valve . So I'll save them and try to get a tap they will fit.
