Stainless Steel Stepless Clamp.
The advantage of this clamp is that the inner circumference is free of any steps or gaps, making them very useful on gas lines for leak proof lines.
11.9mm diameter (uncrimped) - perfect size for clamping 6mm I.D. beer line onto barbed corny connectors or 1/4" barbed shank fittings.
You will need an Ear Clamp Crimper tool, side cutters or end cutters for installation.
