Your cart is empty.A non-perforated worm-drive hose clamp. Ideally suited to applications with high mechanical loads. The key feature of a NORMA TORRO clamp is its asymmetrical construction which provides high clamping force and superior torque strength. Even distribution of clamping pressure. Clamp aligns perfectly on the hose and ensures the optimal sealing of the connection.

These hose clamps are well worth the price. Best money can buy. Doesn't bite into your hoses, can hold up to to a lot of pressure. They're strong and fit very well, using an even amount of pressure.

A properly designed clamp does not require a ton of torque to make a good seal. While these are plenty strong, I've noticed that even when I forgot to torque them down to what I would normally set them to, they still somehow provide an amazing seal on ferncos, vents, etc. I have two of these on a fernco in a slop sink area that constantly gets splashed with water, and thus far, they haven't exhibited any oxidation. Super smooth worm drive as well.Just a great product, you get what you pay for.

I watched a YouTube video where this engineer runs a series of strenuous tests on hardware from different manufacturers. Well, this time around he bought hose clamps from 8 different manufacturers and ran them through pure hell. Every test culminated in the destruction of every single clamp. So, who was the winner? Norma was the clear front runner in nearly all of the tests. This is why I bought a large supply of every single size that Norma makes for my automotive shop. Zero failures to date.

These are great factory quality clamps. You need not to worry about these clamps letting you down.

Sticker on top of box says made in USA. On the inside band of the clamp, they are stamped made in Germany.Clamps are very good quality. They are all 304 stainless which includes screw, housing, and band.Won't tear up hoses like regular clamps.
