Spears 54211168561 Pvc Coupling 1-1/4 in Fnpt Sch 80

Product Description

The SPEARS 54211168561 is a Schedule 80 extra-heavy (XH) standard PVC coupling with female NPT (FNPT) end connections on both ends. Molded from rigid gray PVC, it provides a durable inline connection between two threaded pipe sections. At 1-1/4 inches nominal size, it is suited for pressure piping systems where greater wall thickness and higher pressure ratings are required compared to Schedule 40 fittings. The coupling measures 2-3/16 inches in length with a 2-9/32 inch outer diameter and weighs 0.2 pounds. Licensed plumbers and pipefitters working on industrial, commercial, and municipal systems commonly specify this fitting.

This coupling is used in residential and commercial PVC pressure piping applications including water distribution, industrial process lines, irrigation systems, and chemical handling where PVC is a compatible material. The FNPT end style accepts standard male-threaded pipe ends, making it straightforward to integrate into existing threaded piping runs. Its domestic manufacture and SCH 80/XH schedule rating make it a common specification in projects requiring compliance with stricter pressure and durability standards.

Key Features

• Schedule 80/XH wall thickness for higher pressure ratings versus standard Schedule 40 couplings
• FNPT end style accepts standard male NPT threaded pipe on both ends
• Molded PVC construction resistant to corrosion, chemicals, and moisture
• 1-1/4 inch nominal size fits common intermediate pipe sizing in pressure systems
• Domestically manufactured in the United States
• Compact at 2-3/16 inches length, minimizing added run length in tight installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 80 PVC threaded piping systems using 1-1/4 inch nominal FNPT connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable IPC and local plumbing codes. Depressurize and drain the piping system fully before removing or installing any threaded fittings. Apply PTFE tape or an approved thread sealant to the male pipe threads before engagement — do not apply sealant to the female coupling threads. Hand-tighten first, then use strap wrenches appropriate for PVC to avoid cracking the fitting body from over-torquing.
