Stainless Stepless Clamp Suits 10.5-12.5mm OD (12.8) Pack of 10x units

These stainless clamps are the best for securing your beer and gas line to barbs/nipples. Unlike other hose clamps they secure the line in a complete and exact circle. Hence the name "stepless" clamps. The clamps can be secured with a special crimping tool however normal wire cutters work just as well.
