Rubber Fab’s Armor Casing feature is a highly flexible, heavy duty metal casing which protects the hose against rough handling and over bending. This Armor Casing hose protectant can be applied over the entire length of the hose or on short sections at the connection. Armor Casings of 12-18″ can be applied to each end of the hose to prevent kinking and over stress. This great hose accessory is a must have for protecting hoses in high traffic areas. The Armor Casing does what its name implies!
