Tectran HK350 Constant Torque Hose Clamp to Range - 2-3/4 3-5/8 5-Pack

The Tectran HK350 constant torque hose clamp provides reliable, consistent clamping force for heavy-duty truck, trailer, and commercial vehicle applications. Designed to maintain optimal tension across temperature fluctuations and vibration, this clamp prevents leaks and hose damage that can occur with traditional worm-gear clamps.

Key Features:

• Clamping range: 2-3/4" to 3-5/8" (69.9mm to 92.1mm)
• 5/8" band width for increased surface contact and grip
• 90 in-lb high torque rating for secure connections
• Constant torque design automatically compensates for thermal expansion and contraction
• Prevents over-tightening and under-tightening issues
• Corrosion-resistant construction for long service life
• Pack of 5 clamps for multiple repairs or installations

Ideal for air intake systems, coolant hoses, turbo connections, and other critical fluid or air transfer applications where consistent clamping pressure is essential. The constant torque mechanism maintains proper seal integrity even as hoses age and components undergo thermal cycling during normal operation.
