Introduction
Constant Torque Hose Clamps
Due to extreme temperature changes, hose will heat set.
Heat setting can cause hose clamps to loosen. Loose
hose clamps can result in leaks. Constant torque of hose
clamp helps prevent leaks.
FIG. 32: Constant torque hose clamp is installed
correctly under the following conditions:
• Screw tip (1) extends 6.35 mm (.25 inch) (A) beyond
housing.
• Belleville washers are collapsed nearly flat after
screw (2) is tightened to a torque of 11 Nm (8.1 lb/ft).
