Plastic Barbed Hose Fittings for Water
Made of polypropylene, these fittings have good corrosion and abrasion resistance, and are lighter in weight than metal barbed hose fittings. Slide the barbed end into plastic or rubber hose and secure with a clamp.
Fittings with a threaded end are also known as hose nipples.

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.
- Maximum Pressure: See table
- Temperature Range: -40° to 210° F
