These fittings are to be installed by a fully trained assembler and are designed to be used with W10H and W12H Concrete hose stems (on the WFT/WFW Heavy Duty Flanged ends, the ferrules are pre-attached onto the stem at the factory). The WT- ferrules are for use on textile reinforced concrete hose and the WW- are for wire reinforced. One ferrule fits all hose OD's or wall thicknesses. We DO NOT recommend repairing concrete hose as the wall/tube wears, and recoupling has reduced integrity/coupling strength.

Warning: << Do not repair concrete hoses, critical application
