Dura Plastic L181000 Pvc Reducing Bushing 3/4x1/2 Mnpt Fnpt

Product Description

The DURA PLASTIC L181000 is a Schedule 40 PVC reducing bushing with a 3/4-inch male NPT (MNPT) outer thread and a 1/2-inch female NPT (FNPT) inner thread. It is used to step down pipe or fitting connections from a 3/4-inch nominal line to a 1/2-inch nominal line within a pressurized or drain plumbing system. The bushing is molded from domestic PVC material, making it lightweight, corrosion-resistant, and suitable for cold and ambient-temperature water service. Licensed plumbers and pipefitters install this type of fitting when reducing threaded branch connections or adapting inline runs in residential and light commercial piping assemblies.

This reducing bushing is suited for potable water supply lines, irrigation systems, and general plumbing applications where a threaded size reduction is required. Its Schedule 40 wall thickness meets standard pressure ratings for PVC threaded fittings. The compact hex-shoulder design allows installation with standard pipe wrenches or channel-lock pliers without requiring special tooling. It is commonly used in residential construction, commercial mechanical rooms, and retrofit plumbing where line sizes must be reduced at a threaded connection point.

Key Features

• 3/4-inch MNPT to 1/2-inch FNPT configuration for in-line size reduction
• Schedule 40 wall thickness for standard PVC pressure service
• PVC construction offers corrosion resistance and chemical compatibility with common water treatment additives
• Domestic manufacture
• Lightweight design simplifies handling and installation in tight spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 40 PVC threaded piping systems using 3/4-inch to 1/2-inch NPT connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing code requirements. Shut off and depressurize the water supply line before removing or installing any threaded fitting. Apply PTFE thread tape or an approved pipe thread sealant to the male threads before engagement. Do not overtighten PVC threaded fittings with power tools, as excess torque can crack the socket or distort the threads.
