HydroSure Ratchet Clamp - 13mm - Pack of 100

These ratchet clamps are designed specifically for 13mm (approximately 1/2 inch) diameter irrigation tubing.

Yes, the ratchet mechanism allows them to be opened (usually with some effort or a small tool) and reapplied, though repeated opening may slightly reduce their grip over time.

Yes, they are made from UV-stabilised materials, making them ideal for long-term outdoor and above-ground use in irrigation systems.

The ratchet design provides a more secure, permanent-feeling lock that is less prone to slipping under pressure compared to a spring clamp, and it offers a more consistent tightening force.

This is a bulk pack containing 100 ratchet clamps.

No, these clamps are made from plastic and are therefore rust-proof.

Ensure the tubing is fully seated onto the fitting's barb and that the clamp is positioned correctly over the entire connection. Check that the clamp is properly engaged by squeezing until the ratchet clicks.

The clamp may not be fully tightened or is misaligned. Remove the clamp, re-seat the tubing onto the fitting, and reapply the clamp, ensuring it clicks securely. For persistent leaks, inspect the tubing for damage or the fitting for blockages.

Ensure the clamp is oriented correctly. Apply firm, steady pressure to close the jaws until the ratchet engages. If it feels excessively stiff, check for debris within the ratchet mechanism.
