These top-quality furniture-grade PVC 4-way connectors (also referred to as 4-way elbows or 4-way tees) are UV-resistant and impact resistant. These fittings are compatible with either 1-1/4" furniture-grade PVC pipe or 1-1/4" Schedule 40 PVC pipe.
Note: Just like a 2x4 piece of wood doesn't really measure 2" by 4", 1-1/4" PVC pipe and fittings are identified by nominal sizes and don't actually measure those dimensions. The exact measurements vary slightly from manufacturer to manufacturer, but 1-1/4" PVC pipe actually has an outside diameter (o.d.) of 1.660". The 1-1/4" fittings we sell are designed to be used with PVC pipe that is identified as 1-1/4" pipe when you purchase it.
