Clamp
Mack

This clamp provides reliable hose or tube retention under rugged operating conditions. It offers strong radial pressure around the hose wall to prevent leaks at feed and return lines, as well as shielded areas against abrasion and movement in the engine bay. The clamp design focuses on swift, tool‑free adjustment or secure tightening with a standard screwdriver or torque tool, depending on the model. Proper clamping avoids slip‑off, reduces vibration transmission to hoses, and defends against leaks that could lead to contamination or reduced performance. Material choice—stainless steel, zinc plated, or coated variants—determines corrosion resistance in fuel, oil, and coolant systems. When selecting, consider the diameter range, the expected temperature exposure, and the level of stress the connection will endure. Regular inspection ensures clamps remain tight and undamaged, preserving system integrity. Source One Parts Center.
