DEWALT Cordless PEX Expansion Tool DCE400D1 20V MAX Tube Expander Kit (3/8 to 1 Inch Type A Automatic Rotating Head Plumber Pipe Fitting System)

Automated Rotating Expansion Head for Leak-Free Type-A Plumbing Connections

The DEWALT DCE400D1 20V MAX Cordless PEX Expansion Tool is a battery-powered plumbing tool engineered to expand Type-A PEX tubing ranging from 3/8 inch to 1 inch in diameter. This professional-grade hand tool utilizes an automatic rotating head mechanism to ensure symmetrical pipe expansion, minimizing material stress and potential future leaks at critical junctions. Designed with a full-trigger actuation setup for one-handed operation in confined spaces, this complete kit provides fast mechanical rough-ins for residential and commercial potable water plumbing lines.

Best Used For:

• Potable Water Rough-Ins: Expanding flexible PEX Type-A tubing networks uniformly across entire residential framing and joist bays.
• Confined Cabinet Plumbing: Making quick structural modifications and secure pipe transitions in dark under-sink areas and compact utility spaces.
• Commercial Water Service Maintenance: Expanding cold and hot plumbing lines up to a maximum operating temperature of 210°F safely.

Key Performance & Safety Features

• Automatic Head Rotation: Mechanical indexer turns the expansion segments automatically after each cycle for perfectly uniform tube expansion.
• One-Handed Actuation Trigger: Full-grip switch design facilitates safe, comfortable tool handling when maneuvering in cramped structural configurations.
• Universal Head Interactivity: Accepts standard DEWALT expansion segments and is cross-compatible with leading competitive brand expansion heads.
• Integrated LED Work Light: High-output onboard diode array illuminates dim building areas, crawlspaces, and pipe chases directly.
• Dual-Sided Storage Hooks: Heavy-duty belt clip and integrated rafters hook provide immediate structural tool storage on ladders or plumbing racks.
