Bk 164-103 Schedule 80 Pvc Union 1/2 in Threaded

Product Description

The BK 164-103 is a 1/2-inch threaded Schedule 80 PVC union designed for use in pressure piping systems where a removable, leak-tight connection is required. Molded from heavy-duty Schedule 80 gray PVC, this union provides greater wall thickness and pressure ratings than Schedule 40 fittings, making it suitable for industrial, chemical, and plumbing applications where added strength is a priority. Threaded ends conform to ANSI B2.1 standards, ensuring consistent thread form and reliable engagement with standard NPT-threaded pipe and fittings. Plumbers and pipefitters install this fitting when a section of piping must be periodically removed or serviced without cutting the line.

This union is used in residential and light commercial plumbing, irrigation systems, chemical feed lines, and pool or spa equipment installations where PVC piping is the specified material. The 1/2-inch size suits branch lines, equipment connections, and other lower-flow applications. Its gray PVC construction resists corrosion and many common chemicals, making it a practical choice wherever metal fittings would be subject to rust or chemical attack.

Key Features

• Schedule 80 PVC construction provides heavier wall thickness and higher pressure rating than Schedule 40
• Threaded ends conform to ANSI B2.1 NPT standard for consistent fit with standard pipe and fittings
• Gray PVC material resists corrosion and a wide range of chemicals
• Union design allows the pipe section to be disconnected and reconnected without cutting
• 1/2-inch size suits branch lines and equipment connections

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/2-inch Schedule 80 PVC threaded piping systems using ANSI B2.1 NPT thread form.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC and local plumbing code requirements. Depressurize and drain the line completely before removing or installing any union. Apply an appropriate PVC thread sealant or PTFE tape to all threaded joints; do not use solvent cement on threaded connections. Hand-tighten first, then use strap wrenches or smooth-jaw pliers to avoid cracking the PVC body — do not over-torque.
