HPS Performance Products CTHD-450 Constant Tension Hose Clamp 3-9/16" - 4-1/2" Range 5/8" Band

The HPS Performance Products CTHD-450 constant tension clamp delivers reliable, self-adjusting clamping force for high-performance cooling systems, turbo applications, and exhaust connections. Engineered with a spring-loaded mechanism that automatically compensates for thermal expansion and contraction, this clamp maintains consistent pressure to prevent leaks even under extreme temperature fluctuations.

Key Features:

• 304 stainless steel band construction resists corrosion and withstands continuous high-temperature exposure
• Spring-loaded tension mechanism automatically adjusts to hose expansion and contraction
• 5/8" wide band provides optimal clamping surface area and pressure distribution
• Clamping range: 3-9/16" to 4-1/2" diameter (90.5mm to 114.3mm)
• Smooth spot-welded liner protects soft silicone and rubber hoses from cuts and abrasion
• Compatible with rubber, silicone, and thermoplastic hoses
• Ideal for intercooler piping, radiator hoses, turbo couplers, and exhaust connections

Unlike traditional worm-gear clamps that can lose tension over time, constant tension clamps maintain even pressure across the entire hose circumference, ensuring a secure, leak-free seal in demanding automotive, marine, and powersports applications.
