Bk 404-480 Schedule 80 Pvc Nipple 3/4 X 48 in Ips Npt

Product Description

The BK 404-480 is a Schedule 80 PVC threaded nipple rated for transport of water and a wide range of compatible liquids. Measuring 3/4 inch in diameter and 48 inches in length, this nipple is manufactured to IPS (iron pipe size) dimensions and threaded to NPT (National Pipe Thread) standards. It meets ASTM D1785 specifications, confirming dimensional accuracy and material consistency. The heavier wall thickness of Schedule 80 construction provides greater pressure tolerance than Schedule 40. Plumbers and pipefitters install this nipple as a direct threaded connection between fittings, valves, and piping assemblies in both supply and process piping systems.

This nipple is suited for residential and light commercial plumbing installations where a straight pipe extension or close connection is needed. Common applications include water supply lines, irrigation systems, chemical transfer, and industrial process piping where PVC is an approved material. The 48-inch length makes it useful for longer runs between threaded connection points without requiring additional couplings. Pipe thread compound or sealing tape should be applied to the threaded portion prior to assembly to ensure a leak-free joint.

Key Features

• Schedule 80 PVC construction meets ASTM D1785 specifications
• IPS dimensions with NPT threading for broad compatibility with standard fittings
• 3/4 inch diameter x 48 inch length for longer threaded runs
• Suitable for water and a variety of compatible liquid transport applications
• Heavier wall thickness compared to Schedule 40 for improved pressure handling

Compatibility

Designed as an OEM-style replacement and standard-fit component for 3/4 inch NPT threaded plumbing systems using Schedule 80 PVC fittings, valves, and piping assemblies.

Installation Notes

Installation is typically performed by licensed plumbers or qualified pipefitters. Always shut off the water supply and depressurize the line before making or breaking threaded connections. Apply pipe thread compound or PTFE sealing tape to the male threads before assembly to prevent leaks. Follow applicable local plumbing codes and IPC guidelines for PVC pipe installation, including support spacing and allowable service conditions.
