This hose is a standard 3" diameter and lays flat to roughly 5" wide, matching common 3" filter outlets and many cam lock or pin-lug fittings. It also adapts to smaller schedule 40/80 PVC pipe (2.5" or less) when used with appropriate clamps or adapters.

• Standard 3" inner diameter to match most backwash outlets
• Flat width ~5" when laid out for secure clamping
