Bk 403-050 Schedule 80 Pvc Nipple 1/2 X 5 Inch Npt

Product Description

The BK 403-050 is a Schedule 80 PVC threaded nipple sized at 1/2 inch by 5 inches, designed for the transport of water and compatible liquids in pressure-rated piping systems. The nipple is machined to IPS (iron pipe size) dimensions and threaded to NPT (National Pipe Thread) standards, ensuring consistent fit with standard threaded fittings and valves. It meets ASTM D1785 specifications for rigid PVC pressure-rated pipe. Plumbers and pipefitters install this nipple as a short threaded connector between fittings, valves, or equipment ports in both above-ground and in-wall applications. Pipe thread compound or PTFE sealing tape must be applied to the threaded portion before assembly.

This nipple is suitable for a wide range of residential and light commercial plumbing applications involving water and other compatible liquids. Common install scenarios include connecting shut-off valves, unions, couplings, and threaded adapters in cold and cool water distribution lines. Its Schedule 80 wall thickness provides greater pressure tolerance and impact resistance compared to Schedule 40, making it well suited for applications where additional mechanical strength is required.

Key Features

• Schedule 80 PVC construction provides higher pressure rating and heavier wall thickness than Schedule 40
• IPS dimensioned and NPT threaded for compatibility with standard pipe fittings and valves
• Meets ASTM D1785 specifications for rigid PVC pressure pipe
• 1/2 inch x 5 inch sizing suits common residential and commercial connector applications
• Pipe thread compound or sealing tape should be applied prior to assembly for a leak-free joint

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard NPT threaded Schedule 80 PVC piping systems using 1/2 inch pipe size.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC or local plumbing code requirements. Shut off the water supply and depressurize the line before removing or installing any threaded nipple. Apply pipe thread compound or PTFE sealing tape to the male threads before hand-tightening, then snug with a pipe wrench — do not over-tighten PVC threads, as excess torque can crack the fitting. Avoid using this nipple with incompatible solvents or liquids not rated for PVC contact.
