Cambridge Resources 506985 Galvanized Nipple 1-1/4x3-1/2

Product Description

The CAMBRIDGE RESOURCES 506985 is a galvanized steel nipple fitting designed for threaded pipe connections in plumbing and mechanical systems. Measuring 1-1/4 inches in diameter by 3-1/2 inches in length, this close-tolerance nipple provides a corrosion-resistant connection point between threaded fittings, valves, and pipe sections. The hot-dip galvanized finish protects against rust and oxidation in both indoor and outdoor installations. Licensed plumbers and pipefitters install this type of fitting during new construction, retrofit work, and repair service on water supply, gas, and general piping systems.

This galvanized nipple is suited for residential and light commercial piping applications where a 1-1/4-inch threaded connection is required. Common uses include connecting gate valves, unions, tees, and elbows within water supply lines, heating system piping, and similar low-pressure mechanical systems. It is sold as a single unit and is compatible with standard NPT threaded fittings and pipe of the same nominal diameter.

Key Features

• Galvanized finish provides corrosion resistance for long service life in wet or humid environments
• 1-1/4-inch nominal pipe size fits standard NPT threaded components
• 3-1/2-inch length suits common close-nipple and extension applications
• Threaded both ends for straightforward assembly with standard pipe wrenches

Compatibility

Designed as a standard replacement or new-installation nipple for 1-1/4-inch NPT threaded plumbing and mechanical piping systems.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter following applicable IPC and local plumbing code requirements. Shut off and depressurize the supply line before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly to ensure a leak-free joint. Use a pipe wrench sized to the fitting and avoid over-tightening, which can crack fittings or distort threads.
