Bk 403-025 Schedule 80 Pvc Nipple 1/2 X 2-1/2 Inch Npt

Product Description

The BK 403-025 is a Schedule 80 PVC nipple designed for the transport of water and other liquids in residential and commercial piping systems. Measuring 1/2 inch in diameter and 2-1/2 inches in length, this nipple carries IPS (iron pipe size) dimensions and is threaded to NPT (National Pipe Thread) standards on both ends. The Schedule 80 wall thickness provides greater pressure resistance than Schedule 40, making it suitable for demanding plumbing and industrial applications. Plumbers and pipefitters install this fitting as a short connector between valves, fittings, or threaded pipe ends. It meets ASTM D1785 specifications for PVC pressure-rated pipe and fittings.

This nipple is well suited for water distribution, irrigation, chemical handling, and general-purpose liquid transport lines where threaded PVC connections are required. Its corrosion-resistant PVC construction makes it appropriate for both above-ground and certain below-ground installations. The fitting is commonly found in residential plumbing rough-in work, light commercial mechanical rooms, pool and spa equipment plumbing, and industrial process piping where NPT threaded connections are the standard joining method.

Key Features

• Schedule 80 wall thickness for higher pressure ratings compared to Schedule 40
• IPS dimensions threaded to NPT standards for compatibility with standard pipe and fittings
• Meets ASTM D1785 specifications for PVC pressure pipe and fittings
• PVC construction resists corrosion and chemical degradation in liquid service
• Apply pipe thread compound or PTFE sealing tape to threaded portion before assembly

Compatibility

Designed as a standard NPT-threaded Schedule 80 PVC nipple compatible with 1/2 inch IPS threaded PVC fittings, valves, and pipe conforming to NPT thread standards.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC requirements. Shut off and depressurize the water supply before removing or installing any threaded fitting. Apply pipe thread compound or PTFE sealing tape to the male threads before assembly to ensure a leak-free seal. Do not overtighten PVC threaded fittings, as excessive torque can crack the fitting body.
