Product Details

General Details

external pvc coupling coupler formufit furniture grade pvc

FORMUFIT External PVC Couplings seamlessly extend PVC pipe segments, providing inline connections for lengthening pipes. These straight couplings also enable breakdown points within PVC structures or assemblies. Designed to fit over PVC pipe, they create smooth, slightly raised connections for enhanced stability and durability.

Design
External Furniture Grade PVC pipe couplings have no markings, barcodes, or printing, so they have a beautiful, clean appearance. Their plain and straightforward design looks excellent on structural PVC projects and DIY pipe arts.
Materials
External PVC Couplings are specifically developed to be impact-proof, ultraviolet (UV) resistant, and look great. PVC External Pipe Couplers are extremely strong and durable and will last decades and can be used directly in the sun.
Product Use
External PVC couplers are perfect for extending PVC pipe lengths or creating breakdown points in a project. Simply insert and cement pipes into each end. For removable segments, cement one side and press or screw the other, enabling modular, flexible designs.
Securing
External Couplers will work with Schedule 40, 80, and Thinwall thicknesses of pipe. External Couplings can be assembled by the press-to-fit insertion method or can be permanently attached via PVC glue for a fusion weld.
