The Koul Tools EZ-ON Hose Press, No. 409B, is designed to install -4 to -16 push-lok fittings in a matter of seconds without heating the hose, the company says. It features a patented lead-screw system that requires only a ratchet or small impact gun to assemble hoses quickly and safely, in-house or on-site. Simply secure the fitting in the tool’s vice, clamp the hose in its travelling carriage, and turn the drive screw system to install the hose. An accessory kit is available for 5/16” and 3/8” straight and elbow connectors for users needing to install nylon fuel line.
