Bk 404-080 Schedule 80 Pvc Nipple 3/4 X 8 Inch Npt

Product Description

The BK 404-080 is a Schedule 80 PVC nipple sized at 3/4 inch diameter by 8 inches in length, designed for threaded pipe assemblies in plumbing, irrigation, and industrial piping systems. Manufactured to ASTM D1785 specifications, this nipple features IPS (iron pipe size) dimensions and NPT (National Pipe Thread) threading on both ends. Its heavier Schedule 80 wall thickness provides greater pressure resistance compared to Schedule 40, making it a reliable choice for applications where durability and strength matter. Licensed plumbers and pipefitters rely on this fitting for water service lines, chemical transport, and a broad range of liquid conveyance tasks.

This nipple is suited for residential and light commercial plumbing installations where PVC threaded connections are required. Common applications include water distribution, irrigation manifolds, pump discharge assemblies, and industrial process piping carrying compatible liquids. The NPT thread profile ensures compatibility with standard threaded fittings, valves, and pipe assemblies throughout the system. It is appropriate for use wherever Schedule 80 PVC material meets the chemical and pressure requirements of the application.

Key Features

• Schedule 80 PVC construction meets ASTM D1785 specifications for material and dimensional consistency
• IPS sizing with NPT threading for direct compatibility with standard threaded pipe components
• 3/4 inch diameter by 8 inch length suits a wide range of close-nipple and extension applications
• Heavier wall than Schedule 40 for increased pressure capacity in demanding installations
• Suitable for water and other liquids compatible with PVC piping material

Compatibility

Designed as an OEM-style replacement and standard-use fitting for Schedule 80 PVC threaded piping systems using 3/4 inch NPT connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable IPC (International Plumbing Code) requirements. Apply pipe thread compound or PTFE sealing tape to the threaded portion of the nipple before assembly to ensure a leak-free connection. Hand-tighten first, then use a strap wrench or pipe wrench to finish — avoid overtightening PVC threads, as this can crack the fitting. Shut off and depressurize the water supply before removing or replacing any threaded fitting in the line.
