Merit Brass 3601D-02 90 Degree Pipe Elbow 1/8 in 316SS

Product Description

The MERIT BRASS 3601D-02 is a 90-degree threaded pipe elbow designed for high-pressure piping systems requiring corrosion-resistant materials. Constructed from 316 and 316L stainless steel, this fitting connects two female NPT (FNPT) threaded pipe runs at a right angle and is rated to 3,000 psi. The 1/8-inch fitting size makes it well suited for small-bore instrumentation lines, hydraulic circuits, and process piping where tight routing and reliable sealing under pressure are critical. Licensed plumbers and pipefitters are the typical installers for this class of fitting.

This elbow fits 1/8-inch threaded pipe and is appropriate for residential and commercial applications where stainless steel is specified for resistance to corrosion, elevated temperatures, or chemical exposure. Common installations include compressed air lines, fluid transfer systems, chemical process piping, and marine or coastal environments where standard carbon steel fittings would degrade. The FNPT x FNPT configuration accepts male-threaded pipe or fittings on both ports.

Key Features

• 316 and 316L stainless steel construction for superior corrosion resistance
• 3,000 psi pressure rating suitable for high-pressure piping systems
• FNPT x FNPT threaded end connections for standard NPT pipe compatibility
• 90-degree elbow geometry for right-angle direction changes in tight spaces
• 1/8-inch fitting size for small-bore instrument and process lines

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/8-inch NPT threaded piping systems requiring 316 or 316L stainless steel construction.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code (IPC) or ASME B31 piping standards. Shut off and depressurize the system completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly, and tighten to snug fit without overtightening, which can crack the fitting or distort threads. Do not use this fitting beyond its rated pressure or in applications involving incompatible media without verifying material suitability.
