These check valves help prevent unwanted backflow in smaller size hoses.
Flapper valves are standard, but duckbill and umbrella valves also available by special order; inquire at 800-426-6930.
• Prevents fluid backflow
• Durable, lightweight Acetal plastic
• Models available to accommodate 1/2" - 3/4" hose
Note - these barbed valves are made using a 74-8 check valve, so in a pinch, removing the barbs would allow you to use this check valve with 1" hose.
