About Conduit

Metal Garden Hose Fittings

Connect these fittings to rubber or plastic garden hose for a variety of water supply applications.

Zinc fittings have good corrosion resistance. 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. Fittings with a fasten-on barbed end provide a more secure hold than clamp-on fittings and fittings with gripping tabs; slide the hose over the internal barb and tighten the clamp around the hose with the included screws.
