The Kleerband Flange Protectors provide a quick and easy way to apply protection and prevent corrosion. The devices are simple to install with a worm-gear connection, without the need for special tools. They feature a positive-loading relief-valve vent and plug that ensures complete loading of flange cavities. A transparent and flexible polyband allows for 360-deg uninterrupted inspection, without the need to remove the protector. The protectors are designed to fit all DIN and ANSI flanges from ½- to 144-in. dia. — Allison Engineering, Basildon, U.K.
