YDS Stainless Steel Hose Clamps 1/2" to 1" are high quality hose clamps. They can take a good amount of torque without slipping. However, the 1/2" size can be a little oversized. I used it on a 5/8" hose and the yoke was as small as possible and I had to twist it hard to keep it from leaking. If it a 1/2" hose would be I don't think it would still be round and might not work. For 1/2" I would recommend a 1/4 - 5/8" clamp.
