Features and Advantages

Features and Advantages

  • “Constant Tension” Performance – Belleville spring mechanism permits the clamps to automatically increase or decrease diameter due to operational or environmental temperature changes.
  • Extended Inner Liner – Protects silicone and other soft hoses from damage, extrusion or shear.
  • Quadra-Lock Housing – Four-piece, Quadra-lock housing design: added saddle eliminates risk of seam separation, virtually eliminating housing “lift and twist”.
  • Evenly Distributed Radial Pressure – Quality controlled to military standard specifications for even distribution of sealing pressure. Eliminates leakage caused by uneven housings and provides higher sealing pressure with lower applied torque.
  • Heavy Duty Stainless Steel Band – 300 Series stainless steel band provides durability and superior corrosion resistance. Wider than standard clamps for greater strength.
  • Arched, Perforated Slots – Provides for more overall steel between perforations for added band strength and allows for smoother engagement.
  • Hex Screw - Sharply defined hex angles for better gripping power. More threads per screw for increased torque strength.
  • Meets Industry Standards – Clamps are SAE J1508 Type SLDH and RoHS compliant.
  • Torque Rating – Suggested installation torque of 90 inch pounds.
