The MERIT BRASS 4506-3600 is a seamless stainless steel pipe nipple sized at 3/8 inch pipe, manufactured to Schedule 80 wall thickness in Grade 304 stainless steel. Schedule 80 construction provides heavier wall thickness compared to Schedule 40, making this nipple suitable for higher-pressure and corrosive-environment applications. Grade 304 stainless steel delivers strong resistance to oxidation and a broad range of chemicals encountered in plumbing, HVAC, and industrial piping systems. Licensed plumbers and pipefitters install this type of nipple as a short connector between fittings, valves, and equipment in both new construction and retrofit work.
This pipe nipple is used in residential and light commercial plumbing, HVAC hydronic piping, and industrial fluid-handling systems where corrosion resistance is required. The 3/8 inch pipe size fits common small-bore applications such as condensate lines, chemical feed lines, compressed air distribution, and steam service where Schedule 80 wall thickness is specified. Its seamless construction eliminates weld seams, which reduces potential leak points and improves pressure integrity in demanding service conditions.
Designed as an OEM-style replacement or new-installation fitting for 3/8 inch Schedule 80 threaded pipe systems using standard NPT connections.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and local plumbing code requirements. Shut off and depressurize the system fully before removing or installing any threaded nipple. Apply an appropriate thread sealant or PTFE tape rated for the service fluid before making up the connection. Do not over-tighten threaded stainless steel fittings, as galling can occur — use a calibrated torque wrench or follow the fitting manufacturer's recommended engagement turns.
