Bk 408-040 Schedule 80 Pvc Nipple 2 in X 4 in

Product Description

The BK 408-040 is a Schedule 80 PVC nipple measuring 2 inches in diameter by 4 inches in length, designed for the transport of water and other compatible liquids in pressurized piping systems. Machined to IPS (iron pipe size) standards and threaded to NPT (National Pipe Thread) specifications, this nipple meets ASTM D1785 requirements for rigid PVC pressure-rated fittings. Its thick Schedule 80 wall provides greater pressure capacity and mechanical strength compared to Schedule 40 fittings of the same diameter. Plumbers, pipefitters, and irrigation technicians install this nipple as a close-quarter connector between fittings, valves, and equipment in both above-ground and in-wall configurations.

This nipple is suited for a broad range of residential and commercial plumbing, irrigation, chemical distribution, and industrial fluid-handling applications where a short threaded PVC connector is required. The 2-inch diameter and 4-inch length make it a common choice for connecting valves, unions, and tees in water supply lines, pool and spa plumbing, and process piping. Thread sealant compound or PTFE sealing tape must be applied to the threaded portion before installation to ensure a leak-free joint.

Key Features

• Schedule 80 wall thickness rated for higher working pressures than Schedule 40
• NPT-threaded ends for compatibility with standard pipe fittings and valves
• IPS sizing for direct integration into iron pipe size plumbing layouts
• Meets ASTM D1785 specifications for rigid PVC pressure pipe and fittings
• PVC construction resists corrosion and chemical degradation in liquid transport service

Compatibility

Designed as an OEM-style replacement and standard-use fitting compatible with 2-inch NPT Schedule 80 PVC piping systems in residential and commercial plumbing and fluid-handling applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes and IPC guidelines. Shut off and depressurize the supply line before making any threaded connections. Apply pipe thread compound or PTFE tape to all male threads before assembly to prevent leaks. Do not over-torque PVC threaded fittings, as excessive force can crack the fitting body.
