The VALUE COLLECTION 4SLB901 is a 90-degree street elbow fitting designed for threaded pipe systems requiring a direction change in tight spaces. Constructed from 304 stainless steel, this Schedule 40 fitting connects via a female NPT inlet and a male NPT outlet, allowing it to thread directly into another fitting without a nipple. It carries a pressure rating of 150 psi, making it suitable for a wide range of fluid and gas piping applications. Licensed plumbers and pipefitters install this type of fitting in both new construction and retrofit work.
This street elbow is used in residential and light commercial plumbing, HVAC condensate and refrigerant piping support structures, and general industrial pipe runs where a 90-degree change of direction is needed. The FNPT x MNPT end configuration makes it easy to integrate into existing threaded systems. Its 1-inch fitting size suits common supply and return line diameters found throughout trade work. The 304 stainless steel construction resists corrosion in wet or mildly corrosive environments.
Designed as an OEM-style replacement or new-installation fitting for 1-inch threaded pipe systems using NPT connections in Schedule 40 configurations.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC standards. Shut off and depressurize the pipe system fully before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not over-tighten, as this can crack fittings or distort threads.
