Flex-Gear® clamps use a Belleville spring design to eliminate "cold flow" leakage that adjusts with the hose and fitting to maintain constant tension on the connection, eliminating leak paths. Flex-Gear® clamps are an excellent choice for fluctuating temperature applications and thermal compensation.

Features and Benefits: Belleville spring and clamp construction is built to respond to constant temperature fluctuations. The larger, heavier-gauge, precision-formed springs provide higher rates of band tension and adjustment for a more dependable seal. Inner liner protects against shearing of the hose surfaces.
