Dura Plastic 808-030 Sch 80 Pvc Coupling 3 Inch Fnpt

Product Description

The DURA PLASTIC 808-030 is a Schedule 80 PVC coupling designed for threaded piping systems in industrial, commercial, and residential plumbing applications. Fitted with female NPT (FNPT) threads on both ends, this coupling connects two threaded pipe sections of the same nominal diameter. The 3-inch nominal size makes it suitable for moderate-to-high-flow distribution lines. Schedule 80 PVC wall thickness provides greater pressure tolerance than Schedule 40, making it a common choice where mechanical strength and chemical resistance are both required. Domestic manufacturing is noted by the supplier.

This coupling is used in plumbing, irrigation, industrial process piping, and chemical handling systems where PVC is the specified material. It is a standard threaded fitting appropriate for above-ground and in-wall applications wherever FNPT connections are called for. Licensed plumbers and pipefitters are the typical installers of this fitting class in commercial and industrial settings.

Key Features

• Schedule 80 PVC construction for increased wall thickness and pressure rating over Schedule 40
• Female NPT (FNPT) threaded ends for standard threaded pipe connections
• 3-inch nominal size suitable for moderate-to-high-flow piping runs
• PVC material offers corrosion resistance and chemical compatibility across a wide range of fluids
• Domestically manufactured

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 80 PVC threaded piping systems using 3-inch nominal FNPT connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and local plumbing codes. Always depressurize and drain the system before removing or installing any threaded fitting. Apply thread sealant tape or compound rated for PVC and the specific fluid being conveyed. Do not over-tighten threaded PVC fittings, as excessive torque can crack the fitting body.
