Georg Fischer 861-346 Pvc Nipple 3x12 in Schedule 80

Product Description

The GEORG FISCHER 861-346 is a Schedule 80 PVC threaded nipple measuring 3 inches in diameter by 12 inches in length. Manufactured in gray PVC, this nipple provides a rigid, corrosion-resistant threaded connection for pressure piping systems. Schedule 80 wall thickness gives it greater pressure-handling capability compared to Schedule 40, making it suitable for demanding industrial and commercial plumbing applications. Licensed plumbers and pipefitters install this fitting where a reliable, chemical-resistant threaded extension is required between fittings, valves, or equipment connections.

This nipple is used in industrial process piping, chemical handling systems, irrigation headers, and commercial plumbing installations where PVC is the specified material. The 3-inch diameter and 12-inch length make it a common choice for main line extensions and close nipple configurations in both above-ground and below-grade applications where corrosion resistance and long service life are priorities.

Key Features

• Schedule 80 PVC construction for higher pressure ratings versus Schedule 40
• Gray color finish standard for Schedule 80 pressure piping identification
• 3-inch nominal diameter with 12-inch overall length
• Threaded ends for connection to standard NPT fittings and valves
• Corrosion-resistant PVC material suitable for a wide range of chemicals and fluids

Compatibility

Designed as an OEM-style replacement or standard component for Schedule 80 PVC threaded piping systems using 3-inch NPT connections.

Installation Notes

Installation should be performed by a licensed plumber following applicable IPC or local plumbing code requirements. Use thread sealant or PTFE tape rated for PVC on all threaded connections and avoid overtightening, which can crack PVC fittings. Depressurize and drain the system completely before removing or installing any threaded nipple. Do not use petroleum-based lubricants or solvents not approved for PVC.
