Review on Koehler Enterprises KE28BX Clamp Set by Genene Locson

I have used this micro size 6 on 1/4" (ID) and 5/16" (ID) gas lines. I chose size 6 after asking a sizing question. As for the range, these clamps would go perfectly with both. Well, yes, they go with both, but not "quite well". You must order the smallest size for your application. This is because these clamps do not stay round when tightened, but rather take on a more oval shape, clamping the hose on both sides rather than 360 degrees. I could have ordered a smaller size but I took a workaround that worked pretty well. I tightened the clamps to a round wooden dowel roughly the size of the hose. This kept the clip round but still had too much excess. Choose according to the outside diameter of the hose depending on the maximum reach of the clamp. Otherwise great price and good clip.
