Crimp-On Hose Fittings for Hydraulic Fluid

Crimp these fittings onto hydraulic hose for a permanent, leak-tight connection. Since they crimp on, they handle higher pressure than screw-on fittings. To install, use Parker crimping tools and dies (not included).
Fittings with a female end swivel 360° until tightened without you needing to move or twist the entire hose, making them easy to install.
Fittings with an O-ring face seal end are also known as Seal-Lok fittings.
Note: Fittings are only for use with hydraulic hose.
