Products Tested Tough for the Real World
Some may view clamps as simple commodity items, but in reality, they are highly engineered products that must meet specific criteria in terms of load capacity, tensile strength, leak performance and corrosion resistance. That’s why NORMA clamps are made with the highest quality material and put through 3,000 hours of rigorous product development, engineering and R&D testing to ensure clamp performance that meets or surpasses original equipment quality.
NORMA has an expansive portfolio of hose clamps that can help seal even the most intense connections, including worm drives, T-Bolts and constant-tension clamps. For heavier duty applications, we produce a range of V-Bands and a number of different exhaust clamps to meet varying needs.
In addition, plastics have become a growing market and NORMA is leading the industry with its Quick Connector line – plug-in connectors for cooling water, oil, air or fuel-carrying lines – helping the industry reduce weight and improve permeation rates.
Rounding out the line of more than 40,000 part numbers is a family of mounting and retaining products including muffler and heat shield clamps as well as pipe couplings, which are unique connectors for plain-ended pipes.
