Creative
Copper Wall Light Sculpture
Form sweeping curves with the 1/4 in and 1/2 in copper lines and mount them as a geometric light sculpture. Use the drainage tubing as a soft diffuser over LED strips, the flared fittings as metallic accents, and the wall sleeve as a standoff/spacer for depth. The suction line’s insulation adds contrasting texture, creating a mixed-material statement piece.
Indoor Plant Trellis + Watering Guide
Bend the copper lines into an arch or lattice for climbing plants. Use the included drainage tubing as a discreet watering guide that routes water directly to the pot. Finish the wall penetration with the supplied cover for a clean look if routing the guide through a wall or planter box.
DIY Beverage/Wort Chiller
Coil the 1/4 in liquid line into a compact immersion chiller for cold brew or homebrew wort, and use the 1/2 in line as a pre-chiller loop in an ice bath. The suction line’s insulation can help reduce condensation and temperature loss on the return. Clean and passivate the new copper before any food-contact use, and add hose adapters as needed.
Cable Pass‑Through and Media Wall Finish
Use the included wall sleeve and cover to create a clean, sealed cable pass‑through on a media wall. The sealant bag helps air‑seal the sleeve. Repurpose short sections of copper tubing as hidden cable guides or decorative trim rails behind a TV for a crisp, pro finish.
Garden Misting Arch and Copper Art
Shape an outdoor arch or spiral from the copper lines and add low‑flow misting nozzles along the 1/4 in line for patio or greenhouse cooling. The 1/2 in line adds structure and visual weight, while the drainage tubing can serve as a feed line from a small pump. Use non‑potable water and flush before use.
