Donaldson ’s Stepped SealClamp exhaust clamp, pre-assembled and supplied with few parts requires less torque than other commercially available exhaust clamps and can be fitted with one-wrench installation.
With a reversible threaded nut bar and visual torque indicator, Donaldson’s 360° stepped seal clamp is easy to fit to the desired torque value (50 ft. lbs).
A groove in the clamp head gives a visual indication to the amount of torque being applied, thus helping to ensure the recommended maximum is not exceeded.
The Stepped SealClamp’s 360° stepped shape improves joint seal by reducing exhaust leaks by more than 65% compared to other non-gasketed clamp designs while enhancing resistance to joint separation to nearly twice that of other commercial alternatives.
Conforming tightly to overlapping connections, Donaldson’s Stepped SealClamp is ideal for most overlapping I.D. to O.D. joints and it reduces flex pipe pinching and exhausts noise.
Constructed from quality materials, the Stepped SealClamp is 14-20 lbs lighter than other brands and has a high level of rust resistance. The Stepped SealClamp is available in stainless or aluminised steel with aluminium and zinc-plated components and even comes with high-strength grade 8 fasteners and ranges in sizes 2.50 inch (64mm) to 6.00 inch (152mm).
