The MERIT BRASS 3614D-2406 is a threaded pipe bushing designed to reduce a 1-1/2 inch female connection down to a 3/8 inch male connection in piping systems. Constructed from 316 and 316L stainless steel, this bushing delivers strong corrosion resistance in demanding environments. It carries a pressure rating of 3,000 psi, making it suitable for high-pressure fluid and gas line applications. The male NPT by female NPT (MNPT x FNPT) thread configuration allows direct installation into existing pipe systems without additional adapters. It weighs 0.9 pounds and measures 15/16 inches in length.
This bushing is used in industrial, commercial, and mechanical piping systems where size reduction between pipe runs is required. Typical applications include process piping, chemical handling, marine plumbing, and food-grade or sanitary installations where stainless steel is specified. The 316 and 316L alloy grades provide added resistance to chloride corrosion, making this fitting appropriate for saltwater, chemical, and corrosive-fluid service environments. Licensed plumbers and pipefitters are the primary trade installers for this type of fitting.
Designed as an OEM-style threaded pipe bushing for use in NPT piping systems requiring a 1-1/2 inch to 3/8 inch reduction in 316 or 316L stainless steel service.
Installation should be performed by a licensed plumber or pipefitter. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to NPT threads before make-up. Follow applicable IPC and ASME B31 piping code requirements for the specific service application.
