Stepless Stainless Steel Oetiker Clamps — All Sizes
Stepless (Oetiker-style) clamps create a permanent, leak-free crimp on beer and gas line connections. Unlike worm-drive hose clamps, stepless clamps provide 360° even clamping pressure with no overlap gap — the professional standard for draft beer system installations. Sold individually. $0.40 each.

Why Stepless vs. Worm-Drive Clamps
- 360° clamping — no overlap gap, uniform pressure around the full circumference
- Permanent crimp — requires a clamp tool (pinch pliers), creates a tamper-evident connection
- Industry standard — used by professional draft beer installers and line cleaning companies
- All stainless steel — corrosion-resistant in cooler and cellar environments
Sold individually at $0.40 each. Order the quantity you need — no minimum. Priced for professional installers stocking up.
