Composite Industrial Hoses | Parker | Bottom Loading Hose | 4500 Series

Series 4500 Composite Bottom Loading Petroleum Suction Hose provides excellent service across a variety of petroleum media in medium pressure applications. The hose is lighter weight, more flexible and significantly easier to bend, install and handle than conventional rubber hoses. The hose provides full suction capability, resists crushing and kinking and absorbs vibration, keeping the hose securely in place. The distinctive blue cover is easily identified and the hose is qualified with permanent crimp couplings for a safe and secure connection.
