For joining hoses, this is the style you are looking at. It is a 1-1/2 inch combination hose nipple made from plain steel, built to make a secure hose-to-hose connection in industrial service.

plain steel on this one, does that mean there's no coating or special finish to worry about?

Answer by: Customer Support on Jan 31, 2026, 8:54 AM

Correct, plain steel means no coating, plating, or protective finish has been applied. What you see is bare steel construction. For a combination hose nipple going into a demanding industrial setup, that bare steel build is what gives it the durability and straightforward reliability Kuriyama engineered it for. Just keep in mind your application environment when deciding if plain steel fits your needs.
