Georg Fischer 861-343 Sch 80 Pvc Nipple 3x6 in 185 Psi

Product Description

The GEORG FISCHER 861-343 is a Schedule 80 PVC threaded nipple rated for 185 PSI at 73 degrees F. Machined with male pipe threads on both ends (MPT x MPT), this nipple is designed for use in pressure-rated PVC piping systems where corrosion resistance and chemical compatibility are required. At 3 inches in diameter and 6 inches in length, it fits into mid-size industrial and commercial plumbing runs. Licensed plumbers and pipefitters install this fitting where rigid, solvent-resistant connections are needed. The Schedule 80 wall thickness provides greater strength than Schedule 40, making it suitable for higher-pressure applications.

This nipple is used in commercial and industrial plumbing systems, chemical processing lines, irrigation headers, and water treatment installations. The PVC material resists a wide range of acids, bases, and salts, making it a common choice in facilities where metal corrosion is a concern. Typical installations include pump discharge headers, manifold assemblies, and process piping where threaded connections are preferred over solvent-weld joints.

Key Features

• 185 PSI pressure rating at 73 degrees F
• Schedule 80 PVC construction for increased wall thickness and strength
• Male pipe thread (MPT) on both ends for standard threaded connections
• 3 inch nominal diameter x 6 inch length

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape rated for PVC and the conveyed media. Do not overtighten threaded PVC connections, as PVC threads can crack under excessive torque.
