The Inline Pipe Coupler is designed to create a clean, rigid, straight‑through connection between two pipes. Whether you’re building frames for coro props, structural supports, or custom display elements, this coupler keeps your pipes perfectly aligned in a true 180‑degree configuration.
Compatible with ½" and ¾" PVC or EMT, the Inline Pipe Coupler uses a precision‑fit saddle system that locks both pipes securely in place. The geometry ensures consistent alignment across your builds, making it ideal for straight runs, extensions, and multi‑section framing systems.
Each unit is 3D printed in high‑quality, UV‑resistant PETG for long‑term outdoor durability. ASA is available for extreme heat or maximum UV exposure.
