Genuine Meyer hose 22144 for E-60 and E-57 units, has one male end, and one female end. Attaches to tall elbow on Angle Ram (female end), and Coupler half screws onto male end. Also fits some E-47 and most E-57 units. Meyer eliminated the 90° swivel fittings when they designed the E-57 and E-60 units. This is also the preferred configuration for E-47 units too. The 90° swivel fittings are just a leak waiting to happen. This hose is 45" long, just like 21856 (with the swivel end). Has a 500psi WP and a 20,000 psi Burst pressure rating. This is NOT a cheap plastic hose! The C in the part number stands for "Clamshell" packaging.
