These white pagoda PVC pipe connector fittings are engineered with stepped barb ridges that lock flexible hose in place, eliminating slippage even under sustained water flow.\u003c\/p\u003e\n    \u003cp\u003eEach fitting is molded from rigid white PVC and features a pagoda (stepped barb) profile on the hose-connection end. The pipe-side opening fits 20mm or 25mm PVC pipe OD (select your size above), while the hose-side barb accommodates hose inner diameters ranging from 5mm to 20mm (~3\/16\" to 13\/16\"). Overall fitting length is typically 30–55mm depending on the selected size combination.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include drip irrigation line connections, aquarium filter hose routing, pond pump tubing, and residential grey-water DIY plumbing repairs. Long-tail use cases such as \"PVC pipe to garden hose adapter 20mm\" and \"barbed hose connector for irrigation tubing\" are well served by this fitting's dual-diameter design.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits rigid PVC pipe OD 20mm or 25mm on the socket end.
