Metal Barbed Hose Fittings for Air and Water
Slide the barbed end into rubber hose and secure with the appropriate clamp or crimp-on hose ferrule.
Brass fittings are softer than other metal fittings, so they’re easier to thread together. Plain brass fittings have good corrosion resistance. Nickel-plated brass fittings resist corrosion better than plain brass fittings.
Bronze fittings have better corrosion resistance and are stronger than brass and aluminum fittings. A pipe thread sealant is recommended to seal bronze fittings with BSPP male threads, which is unlike other materials that can often use a gasket.
Aluminum fittings are lighter in weight than other metal fittings. They have good corrosion resistance.
Stainless steel fittings have very good corrosion resistance. 303 stainless steel fittings won’t rust when exposed to water, making them good for areas that require frequent cleanings. Fittings with a threaded end are also known as hose nipples.
Hose connectors are also known as hose menders and splicers. Use them to connect lengths of hose or to repair damaged hose.
Metric, UN/UNF (SAE Straight), and BSPP male threads with gasket protect against leaks.
