Turbo Seal Constant Tension Clamps

Murray Corporation’s Turbo Seal Constant Tension clamps provide excellent protection against leak, loss of boost and hose blow off making them a must-buy for high demand applications.  Turbo Seal clamps lock a hose in place based on the dual spring action design.  The inner Dual Bead Shield ® creates a single spring action by compressing and allowing the clamp to adjust based on temperature changes. The second spring is the outer band of the Turbo Seal clamp, which is convoluted, heat-treated and electro-polished, to further allow for expansion and contraction due to thermal cycling.

The combination of the Dual Bead Liner and the convoluted band act as a dual spring which compensates to offset the effects of cold flow.  As the hose is compressed and the compression set affects the hose, the dual springs help to maintain constant tension on the hose which is how it prevents loss of boost and hose blow off.  The Dual Bead Liner also helps to protect the hose from damages by providing beveled edges that protect against cutting into the expensive silicone hose.  The Liner also helps to distribute the band load evenly to provide a sealing force on the hose in all directions.  This protects against leak paths that can affect the performance of your engine.

Turbo Seal Clamp Properties

  • Rated ultimate torque: 75 in. lbs. min.
  • Recommended installation torque: 50 in. lbs.
  • 300 series stainless steel
  • Decimals range: 1.12 – 8.13
  • 1 1/8” to 8 1/8”

Turbo Seal Clamp Advantages

  • Beveled edges protect soft hose compounds from abrasion and wear
  • Improved life and performance of the hose
  • Low profile, taking up less space under the hood and decreasing the incidence of a snag
  • Provides constant tension
  • Compensates for the effects of thermal cycling and/or compression set of hose
  • Provides dual spring action through convoluted spring action band and the spring effect of the Dual Bead Liner.
