Spears 438-101 3/4" x 1/2" PVC Reducing Bushing, SPGxFPT, Schedule 40

Spears 438-101 3/4" x 1/2" PVC Reducing Bushing, SPGxFPT, Schedule 40

The Spears 438-101 is a Schedule 40 PVC reducing bushing engineered for rough-in pressure piping applications where a transition from a 3/4" line down to a 1/2" branch or fixture connection is required. Configured SPGxFPT (spigot by female pipe thread), this bushing inserts directly into a 3/4" PVC fitting or coupling socket on one end and accepts a 1/2" male-threaded (MIP) fitting, valve, or appliance connection on the other. Molded from PVC in Schedule 40 wall thickness, it's built for solvent-welded pressure systems typical of irrigation, water service, and general plumbing rough-in work behind the wall or underground.

Key Features

• Trade Size: 3/4" x 1/2" reduction, sized for transitioning larger supply lines down to smaller branch connections.
• Durable Construction: Molded PVC body resists corrosion common to steel or brass fittings in buried or wet rough-in locations.
• Connection Type: Spigot (SPG) end solvent-welds into a 3/4" PVC fitting socket; female pipe thread (FPT) end accepts a 1/2" male-threaded fitting, valve, or appliance.
• Schedule 40: Standard Schedule 40 PVC wall thickness for pressure-rated reducing bushing applications.
• Compact Reducer Design: Single-piece bushing eliminates the need for a coupling-plus-adapter combination, saving space in tight rough-in cavities.
