Expansion head for 3/4-inch PEX-A tubing. The head rotates automatically to help produce even expansion, includes etched measurement markings and color-coded bands for size identification, and has chrome and black zinc surface treatments to improve corrosion resistance. It is backward compatible with Milwaukee ProPEX-style expander heads.
Project Ideas
Business
Quick-Add Hose Bibs and Garage Sink Upgrades
Offer a flat-rate service to add or relocate hose bibs and install garage/utility sinks using a 3/4-inch PEX-A trunk and expansion fittings. Market faster installs with fewer leak points, and use the head’s depth marks for documented quality control photos on each joint.
Prefab 3/4-Inch PEX Manifolds for Remodelers
Build and sell pre-assembled 3/4-inch PEX-A manifolds with labeled takeoffs for kitchens, baths, and ADUs. The automatic rotating head produces consistent expansions for a professional look. Include reducers, isolation valves, and mounting brackets in a ready-to-hang kit.
Tiny Home/Van Plumbing Kits
Package a 3/4-inch PEX-A mainline kit with expansion-coupled pump/filter connections and branch reducers to fixtures. Provide color-coded bands and insertion-depth guides that match the head’s markings. Sell as DIY kits with an optional on-site expansion service or tool rental.
Rainwater Harvesting Installations
Specialize in installing 3/4-inch PEX-A header systems for barrel arrays and garden distribution. Promote corrosion-resistant, expansion-based joints that hold up outdoors. Offer seasonal flush and maintenance plans, plus upgrades to filtration/UV for potable applications where permitted.
On-Site PEX Expansion Service and Training
Provide mobile expansion services to handymen and GC crews who lack expander tools. Bring an expander with this 3/4-inch head, verify insertion depths with the etched marks, and document each connection. Upsell short trainings on proper PEX-A expansion techniques and joint inspection.

Rain-Barrel Manifold and Garden Mainline
Build a tidy 3/4-inch PEX-A header that daisy-chains multiple rain barrels and feeds garden zones. Use the expansion head to make leak-resistant connections on 3/4-inch tees, valves, and adapters, then step down to 1/2-inch drip lines. The auto-rotating head helps keep expansions even, and the etched depth marks keep insertions consistent so the manifold stays reliable through seasonal temperature swings.
Outdoor Kitchen Supply Trunk
Run a 3/4-inch PEX-A trunk to a patio sink, prep faucet, and pot-filler. Expansion couplings and tees provide a clean, crimp-free install that resists corrosion outdoors. Color bands and depth etches on the head help track size and insertion for repeatable connections as you branch to 1/2-inch fixtures using reducers.
Greenhouse Header Ring with Zone Valves
Create a circular 3/4-inch PEX-A header around the greenhouse perimeter with expansion tees to zone valves and mist/drip circuits. The rotating head ensures uniform expansions around the ring, reducing weak spots. Add unions for seasonal changes and pressure gauges to monitor each zone off the main header.
Portable Camp Shower + Sink Caddy
Assemble a compact 3/4-inch PEX-A backbone with expansion adapters to a pump, filter, and quick-connect outlets for a shower head and collapsible sink. The larger trunk reduces pressure drop, while reducers feed smaller lines. The corrosion-resistant head surface is handy for field conditions, and the etched marks speed consistent assembly.
Chicken Coop Frost-Resistant Water Loop
Run a 3/4-inch PEX-A supply around the coop with expansion tees to waterers. Use heat tape and insulation over the main loop and rely on robust expansion joints for fewer winter leaks. The even expansion from the rotating head helps maintain seal integrity in freeze/thaw cycles.
