Used with Samsung fridge. Without them, the fridge would make a very loud squeak when the ice maker was full. I first tried a 70psi regulator. The 70 psi device reduced the noise, but it was still there. 40 psi stopped the noise completely. The only downside is that the water in the door is slow. And 50psi adjustable might be the best. The seller actually replaced the fridge. The second refrigerator, of course, made exactly the same noise.
