Frequently Asked Questions

What size hose do these fit?

These clamps fit hose barbs in the 17–21mm diameter range. Measure your hose OD to confirm the size before ordering.

Why are these stepless clamps better?

Stepless design provides uniform 360-degree clamping pressure with no gaps, reducing the risk of hose slippage and leaks compared to traditional worm-gear clamps.

How many are in a pack?

10 clamps per pack — enough for multiple hose connections or to stock spares.

Will these damage my hoses?

No — the specially formed edges are designed to grip without pinching or crushing hose or barb material.
