  • Constant Pressure Design: Equipped with 10 stainless steel Belleville washers that dynamically expand and contract with engine temperatures, eliminating "cold-water leaks" by maintaining constant pressure on the hose.
  • Premium Stainless Steel: The 0.62-inch wide band is constructed from highly corrosion-resistant 300 series stainless steel, while the 3/8-inch hex bolt is made from ultra-hard 410 series stainless to prevent thread stripping.
  • Broad Clamping Range: Provides a versatile clamping range covering outside hose diameters from a minimum of 2.750 inches up to a maximum of 3.620 inches.
  • SAE J1508 Compliant: Manufactured to meet or exceed strict SAE J1508 Type SLF and SLHD specifications, making it fully approved for severe-duty commercial vehicle use.
  • Direct Aftermarket Replacement: Delivers Fleet Standard reliability as a seamless, drop-in alternative to top OEM and industry part numbers like Freightliner 23-12485-250, Tectran HK350, and Donaldson P532926.

Eliminate blown-off charge air cooler hoses and stubborn cold-water leaks with this premium Heavy Duty Constant Torque Clamp distributed by FleetPro Parts & Tires. Manufactured to strict Fleet Standard specifications, this heavy-duty clamping solution is engineered for commercial cooling systems, turbocharger plumbing, and high-pressure air intakes. Standard worm-gear clamps loosen over time due to thermal expansion, but this clamp dynamically adjusts to keep your hoses tightly secured. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.

Leak-Free Sealing: The Heavy Duty Constant Torque Clamp Advantage

This Heavy Duty Constant Torque Clamp (Part # 561.25350) utilizes 10 stainless steel Belleville washers that act as springs, automatically expanding and contracting with temperature fluctuations to maintain a constant grip on your hoses. It features a broad clamping range of 2.750" to 3.620" and is built to survive harsh under-hood environments. The 0.62-inch wide band is stamped from corrosion-resistant 300 series stainless steel, while the 3/8-inch hex screw is forged from high-hardness 410 series stainless steel to prevent stripping. Note: Proper installation requires a torque wrench set to 90 in-lbs; the use of pneumatic or electric impact tools is not advised.

Serving as a professional-grade replacement for highly searched industry part numbers like Freightliner 23-12485-250, Tectran HK350, Donaldson P532926, and Gates 32635, this clamp is an absolute must-have for any shop's hardware bin.
