A constant tension spring hose clamp in stainless steel, which grips a hose by its own spring force rather than by a tightened screw. Because it maintains its grip as the hose and the fitting expand and contract, it does not need re-tightening after a heat cycle.
The clamp takes up the expansion and contraction of hose and fitting, which is what makes screw clamps loosen over time.
Squeeze, position, release. No torque setting, no screwdriver, no risk of an operator over-tightening and cutting the hose.
Hose clamps live where there is heat, water and sometimes chemicals, which is exactly where plated clamps fail.
Position the clamp fully over the spigot barb, not on the hose beyond it. A clamp sitting off the barb provides almost no sealing force.

Available in Stainless steel, Spring steel, Carbon steel, 65Mn, Music wire, in wire from 0.1-8 mm, with any of our nine surface finishing routes. Geometry, end treatment and finish are all specified per order.
ISO 9001, SGS certificate and RoHS report (stated on the legacy site, certificates pending re-confirmation). Certificate copies are sent on request once re-confirmed.
Against a worm drive screw clamp, a spring clamp cannot be over-tightened and does not loosen with heat cycling, but it applies a fixed force that cannot be adjusted.
By the outside diameter of the hose when fitted over the spigot. Send both dimensions and the hose material.
Yes, within reason. Repeated opening with the wrong tool is what damages them.
Purpose-made pliers make fitting easier, especially in confined spaces. Standard pliers work for accessible positions.
Send your drawing, dimensions or a sample. We will confirm the specification and come back with a price and a lead time.
