These stainless crimp 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.
