John Guest Speedfit 3/8 Inch OD Straight Shut Off Valve, Push to Connect Plastic Plumbing Fitting, PPSV041212WP

Ce n'est pas le diametre dont j'ai besoin, mais impossible de l acheter en diametre 15

Great device as I had a small leak in a copper pipe and after using this the leak has been completely fixed. I tried using anti-leak tape & spray but they didn't work on the copper so I took a chance on this and it worked perfectly. Anyone with some basic DIY skills can install this, just make sure you have a great tube cutter on hand.

Pensavo costasse meno ma è esattamente quello che mi serviva al lavoro.Un ottimo prodotto resistente.

Perfect, did the job

Just like all Speedfit John Guest products, this valve attaches quickly and easily to John Guest tubing. The connection is leakproof as always with John Guest fittings. This is used with water pressure of 80 psi, but it is rated for much higher pressures for cold water. The valve is easy to turn and has performed normally over the last eight months, with no leak. We turn the valve back and forth about once a week. If needed, John Guest fittings can be disconnected from tubing using an inexpensive removal tool. There are optional plastic locking collets that can be added to John Guest Speedfit connectors to prevent inadvertent disconnection, but these are rarely used as an accidental disconnect is exceedingly uncommon.By the way, these are made of polypropylene and are NSF61 listed, so they may be used in a food service application with other food safe materials. Ideally, use these with John Guest LLDPE 3/8" tubing to be certain of food safety and excellent fit. I don't recommend using alternative branded (or unbranded) equivalents as you have no assurance of NSF listing and food safety.
