Hexagonal hose clamp for barbed fittings

This clamp secures 16-17 mm tubing onto barbed fittings that lack union nuts. It uses a hexagonal socket screw for a firm grip and a clean look. The design preserves the larger inner diameter that barbed fittings provide over compression types. It is sold new under part number 68121.

For custom water-cooling loops using barbed

Builders who rely on barbed fittings for maximum flow will find this clamp adds the missing mechanical security. It is not for systems built with compression fittings or push-fit connectors, which already lock tubing in place. Buyers needing a tool-free quick-release mechanism should look elsewhere.

16-17 mm clamping range for 5/8 inch barbs

The clamp fits tubing with an outer diameter of 16-17 mm, matching standard 5/8 inch barbed fittings. This single dimension decides whether the part matches your loop. Verify your tubing OD before purchase.
