Metal Barbed Hose Fittings for Chemicals and Petroleum
Made of stainless steel, these fittings stand up to a wide variety of chemicals, as well as fuels, gasoline, and oils. To connect, slide the barbed end into plastic or rubber hose and secure with a clamp.
Adapters are also known as hose nipples; they adapt a barbed end to a threaded end.
Alloy 20 stainless steel fittings resist corrosion better than any other stainless steel hose fitting we offer. They contain nickel, so they withstand exposure to harsh chemicals, such as sulfuric, phosphoric, and nitric acids. Commonly known as Carpenter 20 fittings, they also resist cracking from stress.
