Donaldson Co. says its redesigned Stepped SealClamp Exhaust Clamp is lighter in weight, easier to install and provides reduced leakage on exhaust connections as compared to other designs. Available in stainless and aluminized steel, the Stepped SealClamp is a full 360-degree clamp designed for overlapping tube connections, including muffler inlets, outlets, slotted joints and flex tubing.

The Stepped SealClamp’s shape features an inside sealing surface designed to match the stepped shape of an overlapped joint, providing a seal for minimizing exhaust leaks. The V-grooved installation indicator on the top side is a visual reference to proper torque during installation. The stepped center bar conforms to tubes in overlapping connections to improve the seal at the joint.

Pre-assembled with fewer parts and a reversible threaded nut bar, the Stepped SealClamp can be assembled with one wrench and requires less torque than other designs for easier installation, the company says, and all parts have been treated with a rust-resistant coating to extend product life.
