Merit Brass 3603D-12 90 Degree Street Elbow 3/4 in Ss

Product Description

The MERIT BRASS 3603D-12 is a 90-degree street elbow fitting designed for threaded pipe systems requiring a directional change in a single connection point. Built from 316/316L stainless steel, this fitting handles pressures up to 3,000 psi and resists corrosion in demanding fluid and gas service environments. The street configuration combines a female NPT end with a male NPT end, allowing it to thread directly into another fitting without a nipple. At 3/4 inch, it fits a common pipe size used throughout industrial, commercial, and marine plumbing systems. Licensed plumbers and pipefitters install this type of fitting in both new construction and retrofit applications.

This fitting is suited for high-pressure piping systems where corrosion resistance and material compatibility are critical. The 316/316L dual-grade stainless steel construction makes it appropriate for use in chemical processing, marine environments, food service, and corrosive fluid handling. The threaded FNPT x MNPT configuration simplifies installation in tight spaces where a standard elbow and separate nipple would be difficult to fit. It is commonly used in industrial process piping, HVAC hydronic systems, and plumbing rough-in work requiring a 90-degree directional change at a 3/4 inch threaded connection.

Key Features

• 316/316L dual-grade stainless steel construction for superior corrosion resistance
• 3,000 psi pressure rating suitable for high-pressure threaded pipe systems
• 90-degree street elbow design with FNPT x MNPT ends eliminates the need for a separate nipple
• 3/4 inch fitting size covers one of the most common pipe sizes in commercial and industrial plumbing
• Threaded connection type for straightforward installation with standard pipe wrenches

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/4 inch threaded pipe systems using NPT connections rated for 3,000 psi service.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or ASME B31 piping codes. Depressurize and drain the system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly, and tighten using a pipe wrench to a secure, leak-free connection without over-torquing the stainless steel threads. Inspect for leaks after restoring system pressure.
