Legacy's Flexzilla Push Lock Series of air hoses and fittings allows you to make custom length hose assemblies easily; repairs can be made in seconds without any special tools or clamps. The Series fittings, couplers and plugs are reusable. To make hose repairs, simply cut out the damaged section of hose and remove the reusable Push Lock fittings. Insert the fitting into the undamaged hose using a light air tool oil or rubbing alcohol.
