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.

- Maximum Pressure: 150 psi @ 72° F
- Temperature Range: 10° to 150° F
- Attachment Type: Use Worm-Drive Clamps or Bolt Clamps
Hose Unions for Chemicals and Petroleum

- For Use With: Citric Acid, Cutting Oil, Diesel Fuel, Fuel Oil, Gasoline, Hydraulic Fluid, Mineral Oil, Oil
- Maximum Pressure: See table
Access your line without twisting the hose—these unions separate into three pieces. Also known as WECO couplings and hammer unions, they’re made of forged steel that’s tough enough to be tightened with the blow of a hammer. Use them with other connectors that have the same hammer union figure and pipe size.
Note: Pressure ratings are given for static (constant) pressure conditions with no instantaneous increases in pressure.

Metal Garden Hose Fittings for Drinking Water
These fittings meet NSF/ANSI Standard 61 for drinking water. Connect them to rubber or plastic garden hose for a variety of water supply applications. Fittings are brass for good corrosion resistance.
Fittings that swivel until tightened rotate 360° for easy installation.
Fittings with a barbed end are also known as hose menders and splicers. Use them to connect lengths of hose or to repair damaged hose. To connect, slide the barbed end into rubber or plastic hose and secure with a clamp.
