Bk 405-120 Schedule 80 Pvc Nipple 1 in X 12 in Npt

Product Description

The BK 405-120 is a Schedule 80 PVC threaded nipple designed for the transport of water and a wide range of compatible liquids in plumbing and industrial piping systems. Measuring 1 inch in diameter and 12 inches in length, it is machined to IPS (iron pipe size) standards and threaded to NPT (National Pipe Thread) specification. The Schedule 80 PVC wall thickness provides greater pressure tolerance compared to Schedule 40, making it suitable for more demanding service conditions. Licensed plumbers and pipefitters install this nipple as a close or extension fitting between threaded pipe fittings, valves, and equipment connections. It meets ASTM D1785 specifications and weighs 0.414 pounds.

This nipple is suited for residential and commercial plumbing, irrigation, chemical handling, and industrial fluid-transport applications where NPT-threaded PVC connections are required. Its 1-inch diameter is a common size found in main distribution lines, equipment branch connections, and manifold assemblies. Apply pipe thread compound or PTFE sealing tape to the threaded portion before assembly to ensure a leak-free joint.

Key Features

• Schedule 80 PVC construction for increased wall thickness and pressure capacity versus Schedule 40
• 1 inch x 12 inches nominal size with IPS-standard threading
• NPT threads for compatibility with standard threaded fittings, valves, and couplings
• Meets ASTM D1785 specification for rigid PVC pressure-rated pipe and fittings
• Suitable for water, irrigation, and a broad range of liquid-transport applications

Compatibility

Designed for use with standard 1-inch NPT threaded PVC fittings, valves, and couplings in Schedule 80 PVC piping systems. Compatible with NPT-threaded connections meeting ASTM D1785 standards.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before removing or installing any threaded fitting. Apply pipe thread compound or PTFE sealing tape to the male threads before making up the joint — do not over-tighten, as PVC threads can crack under excessive torque. Inspect threads for damage before installation and ensure mating fittings are also Schedule 80 PVC or rated for equivalent service.
