LASCO 17-1511 1/4-Inch Compression by 1/4-Inch Compression Straight Brass Needle Valve

Update after my 1 star review below.Amazon sent a replacement, no return necessary.The replacement is functioning properly. I recommend this for metering a small supply line.i bought this because i'm looking for a small trickle through my whole-house humidifier. in the neighborhood of under 2 gallons an hour.i have this valve turned off as hard as i can. My water company monitors my flow and makes it available to me online. They say my flow is never less than3 gallons a minute .Even while i'm sleeping!gonna try a different one

This valve provides a simple way to add a shut-off in a 1/4-inch line. If all you need is a shut-off valve, however, there is a version that uses a quarter-turn blade-action valve that I would recommend getting instead. The advantage of this model is that you can open and close it part-way, making it particularly suitable for situations where you may need to regulate the flow of water in the line.

Worked perfectly for my 1/4 RO line utilized for processing maple sap.

Good quality needle valve I use on my reverse osmosis machine for making maple syrup . It lets me fine tune the pressure in the lines

Used on a project and worked quite well.

Worked the first time. NO leaks!!!

Worked like a charm

Good value
