Project Ideas
Business
Micro-Branch Add-On Service
Offer a fast-install service to add 3/8 in PEX-A branches for ice makers, bidets, humidifiers, and RO systems. The automatic rotating expansion head produces uniform, reliable connections that minimize callbacks. Market as a clean, same-day, no-solder upgrade.
Prefab Under-Sink Manifolds
Assemble and sell labeled 3/8 in PEX-A mini-manifold kits (filter, faucet, dishwasher, etc.). Use the etched measurements to standardize cut lengths and the even-expansion head to ensure leak-free joints. Sell online or to local plumbers/handymen for quick installs.
Mobile Expander Rental + Training
Rent out a PEX expansion tool with this 3/8 in head and include a 20–30 minute how-to session. Upsell a fittings/PEX starter pack and a damage-deposit waiver. Backward compatibility with Milwaukee ProPEX heads broadens appeal to users with mixed kits.
RV/Van/Tiny Home Retrofits
Specialize in replacing brittle tubing with 3/8 in PEX-A for fixtures and appliances in mobile and small spaces. The compact, rotating head excels in tight cabinetry and ensures consistent expansions that hold up to vibration on the road.
Hydration Station Installations
Install under-sink filters, bottle fillers, and coffee bar feeds using 3/8 in PEX-A. Promote potable-safe materials and neat, uniform expansions for a professional look. Offer maintenance plans and quick-response leak checks as ongoing revenue.
Creative
Countertop Cold-Brew Tap
Build a compact cold-brew or iced-tea dispenser using 3/8 in PEX-A from a sealed container to a small tap. Use the expansion head’s automatic rotating action to make uniform, leak-free joints on tees and elbows. Since the tubing is rated for potable water and the head resists corrosion, you get a clean, durable beverage line for chilled drinks.
Indoor Herb Drip Halo
Create a circular drip ring around herb pots fed by a small pump. Expand 3/8 in PEX-A to accept tees and adapters for drippers around the ring. The even expansion helps seal consistently so the halo won’t weep at joints, and etched size marks make quick work of measuring repeatable sections.
Aquarium Water-Change Manifold
Assemble a compact manifold that splits a pump’s output via 3/8 in PEX-A to service multiple tanks for water changes. The rotating head ensures even expansion on each port, reducing leak risk over time in a splash-prone environment. Add inline valves for precise control.
Camp/Van Hand-Wash Station
Plumb a jerry can, foot pump, and a simple spout with 3/8 in PEX-A for a portable, durable wash station. The head’s compatibility with common ProPEX tools makes assembly quick, and the corrosion-resistant finish stands up to outdoor use and storage.
Potting Bench Utility Sink
Run 3/8 in PEX-A from a hose bib through a filter to a garden sink on a potting bench. The expansion head delivers snug, even joints in tight quarters under the bench, and color bands help you grab the right head quickly if you keep multiple sizes.
