Vibrant Performance Aramid Reinforced Silicone 45° and 90° Transition Elbows feature High Temperature Resistant Aramid Reinforcement Fabric between each layer of silicone which allows for an impressive Operating Temperature Range of -65° F to 500° F (-54° C to 260° C). These elbows are intended for use in applications where pressurized tubing and connection points require a tight radius bend and size transition to accommodate the installation of piping in limited space. Not suitable for use with Oil/Fuel.
