The MERIT BRASS 4512-4800 is a stainless steel pipe nipple constructed from Grade 304 stainless steel using a seamless manufacturing process. Rated at Schedule 80 wall thickness, it delivers greater pressure capacity than standard Schedule 40 fittings. The 3/4-inch pipe size makes it a common choice for industrial, commercial, and mechanical piping systems where corrosion resistance and wall strength are required. Licensed plumbers and pipefitters typically install this nipple in close or extension configurations within process piping, steam lines, and high-pressure fluid systems.
This nipple is suited for applications in residential and commercial plumbing, HVAC hydronic systems, chemical handling lines, and food-service or sanitary piping where 304 stainless steel is specified. The seamless construction eliminates weld seams, reducing potential failure points under pressure cycling or thermal expansion. It is appropriate for use with threaded fittings and valves compatible with 3/4-inch NPT connections.
Designed as an OEM-style replacement or new-installation fitting for 3/4-inch NPT threaded piping systems requiring Schedule 80 wall thickness and Grade 304 stainless steel material.
Installation is performed by licensed plumbers or pipefitters following applicable IPC and ASME B31 piping codes. De-pressurize and drain the line before removing or installing any threaded nipple. Apply an appropriate thread sealant or PTFE tape rated for the service medium before making up connections. Do not over-torque threaded joints, as stainless steel threads can gall if assembled dry or with excessive force.
