John Guest Speedfit 3/8 x 3/8 x 1/4 Inch Angle Stop Adapter Valve, Push to Connect Plastic Plumbing Fitting, ASVPP1LF

No leaks it works as advertised

This was exactly what I needed.

This works well and is a breeze to install. It can rotate around its axis, so once it tightened you can position the new 1/4 valve where you want it to be. No leaks and is functioning well.

This is just what I needed. Very well made. Its a plastic valve but it looks like it will last a long time. A piece of advice though. the 3/8 refers to the inside of the water supply line. It will fit a 1/2 compression thread. This gets very confusing since it is not specified and a lot of the fittings refers to the thread rather than the inner tube diameter...

muy bueno

Everything was sized as advertised, with exactly the same difficulty of installation as any other adapter. You need to allow space for the valve handle, since its bulkier than the rest of the fitting. The plastic parts dont feel cheap, and the valve was firm enough that it wont be turned accidentally, but still not difficult to turn. This is great under the sink with cleansers and things that might bump into it. If youre looking for a valve to be turned on and off a lot, this is probably not what youre looking for, but its an excellent choice for under-the-sink fittings that will only be used during maintenance or upgrades.

The valve I received today states it is Lead Free and meets the requirements of AB 1953. Californias AB 1953 defines the term “lead free” as an average lead content of 0.25% or less. The last two letters of the part number (LF) indicate this is the lead free model. It was manufactured in the UK.

Works like a charm! This is a quality product. Note that the valve only turns on/off the flow from the divider. It doesnt switch the flow of water between the two outputs.

Thank you for selling this part! I was trying to install a under sink water filter and it came with 1/2 by 1/2 x 1/4 adapter, didnt work with my 3/8 fittings at all! I kept getting leaks. This solved every leak problem and made installation so simple. Best buy ever!

This worked fine, and the plastic valve rotates around the metal fitting, so you can swivel it around to point where you want it to.
