PVC Bush, Sch 80, 1/2" S x 3/8" Fipt — PVC0503STB

PVC Bushing, Schedule 80, 1/2" Socket x 3/8" FIPT is a reducing fitting that adapts a 1/2" slip (socket) connection down to a 3/8" female threaded port. Schedule 80 PVC offers a heavier wall than Schedule 40 for added strength in pressurized plumbing.

• Reducer bushing: 1/2" socket (slip) x 3/8" FIPT
• Schedule 80 PVC for higher pressure capability
• Female iron pipe thread on the reducing port
• Solvent-weld socket end for a permanent glued joint
• Corrosion-resistant, lightweight (approx. 0.02 lb)

Reducing bushings like this let you step a 1/2" PVC line down to a 3/8" threaded takeoff for gauges, small valves, sensors, drain lines, or instrument connections. The socket side is solvent-cemented into a 1/2" fitting or pipe, while the 3/8" FIPT accepts a male-threaded component. Use PVC primer and cement rated for Schedule 80 on the slip joint, apply thread sealant to the FIPT connection, and confirm both port sizes match your existing plumbing before assembly.

Schedule 80 PVC Reducer Bushing

This is a Schedule 80 PVC bushing, part number PVC0503STB, that transitions from a 1/2 inch solvent-weld socket to a 3/8 inch female pipe thread. Reducer bushings are the small adapters that let you step down from one size or connection type to another, in this case letting a 1/2 inch glued pipe accept a 3/8 inch threaded fitting. Schedule 80 is the heavier-wall, higher-pressure grade of PVC, so this bushing is built for demanding plumbing around water treatment equipment.

Where It Fits In

Bushings like this show up wherever the plumbing around a valve, filter, or manifold needs to change size or switch from a glued joint to a threaded one. It might tie a smaller threaded accessory, gauge, or fitting into a larger glued line, or adapt a port so it accepts the connection you actually have on hand. The combination of a solvent socket on one side and a female thread on the other makes it a flexible transition piece.

Installation Guidance

The socket side is cemented onto 1/2 inch pipe with PVC primer and cement, while the 3/8 inch threaded side accepts a male fitting sealed with thread tape or paste. Take care not to over-tighten threaded PVC, since excess torque can crack the fitting even in a sturdy Schedule 80 body. Because exact sizing is critical for a sealed joint, Water Softener Plus is glad to help you confirm that this bushing matches your pipe and fitting sizes, and we include relevant guidance with your order.
