Round Manifolds for Hose Lines


Mount these manifolds on the end of a hose line to distribute air, water, or hydraulic fluid to three locations from a single supply source.
Aluminum manifolds are lighter in weight than stainless steel manifolds and have good corrosion resistance. 303 stainless steel manifolds are more corrosion resistant than aluminum manifolds and have better strength to handle high-pressure applications. 316 stainless steel manifolds have excellent corrosion resistance and can handle fuel, gasoline, coolant and other harsh substances.
Use a plug (sold separately) to close off any unused outlets.
