ETL Performance T-Bolt Clamp for use with 4.00" Inside Diameter Hose Coupling Part Number-221012 **ETL Performance Clamps are designed to work with the thickness of ETL Performance Hoses. ETL Hoses have a wall thickness of 0.25" to allow for a higher burst pressure. If you are unsure of the wall thickness of the hose or have a smaller wall thickness, we recommend sizing down in clamp size.**
