Bk 164-133HC Schedule 80 Pvc Union 1/2 Inch Fip

Product Description

The BK 164-133HC is a 1/2 inch female iron pipe (FIP) threaded union constructed from Schedule 80 PVC. It is designed for joining and disconnecting sections of thermoplastic piping systems without cutting the line. The union features an EPDM O-ring seal that provides a reliable, leak-resistant connection at the mating faces. Rated at 150 psi at 73 degrees F with a maximum service temperature of 150 degrees F, this union is suited for cold and cool-water supply, irrigation, chemical distribution, and industrial fluid handling applications. Plumbers and pipefitters install this fitting where periodic disassembly of a plastic pipeline is required.

This union is a standard choice in residential and light commercial plumbing, pool and spa equipment connections, irrigation mainlines, and industrial process piping. The FIP x FIP threaded configuration accepts male-threaded pipe or fittings on both ends. Because Schedule 80 PVC carries a heavier wall than Schedule 40, it withstands greater mechanical stress and is often specified in exposed or higher-pressure runs. The fitting is compatible with both Schedule 40 and Schedule 80 PVC pipe, giving installers flexibility in mixed systems. White color is standard for PVC pressure fittings.

Key Features

• Heavy-wall Schedule 80 PVC construction rated for higher mechanical loads than Schedule 40
• EPDM O-ring seal at union face for a secure, leak-resistant joint
• Threaded ends comply with ANSI B1.20.1 for consistent thread form and fit
• Rated at 150 psi at 73 degrees F with 150 degrees F maximum service temperature
• Compatible with both Schedule 40 and Schedule 80 PVC pipe
• 1/2 inch FIP x FIP configuration for straightforward threaded assembly

Compatibility

Compatible with both Schedule 40 and Schedule 80 PVC pipe. Designed as a standard threaded union replacement or new-installation fitting for 1/2 inch PVC pressure piping systems.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters. Shut off the water supply and relieve system pressure completely before disassembling or installing the union. Apply thread sealant tape or compound rated for PVC and plastic fittings to the male threads before assembly; do not overtighten, as PVC threads can crack under excessive torque. Follow all applicable local plumbing codes and ASTM standards for plastic pressure piping.
