Merit Brass 6524-4800 Ss Pipe Nipple 1-1/2 in Grade 316 Sch 80

Product Description

The MERIT BRASS 6524-4800 is a Grade 316 stainless steel pipe nipple designed for demanding fluid and gas piping applications across plumbing, HVAC, and industrial service work. Built to Schedule 80 wall thickness from seamless construction, it provides greater pressure resistance and wall uniformity compared to welded alternatives. Sized at 1-1/2 inches pipe size, this nipple serves as a reliable threaded connector between pipe sections, valves, fittings, and equipment in corrosive or high-purity service environments. Licensed plumbers, pipefitters, and mechanical contractors typically install this component during new construction or retrofit work where material traceability and corrosion resistance are required.

This nipple is well suited for residential and commercial piping systems where exposure to moisture, chemicals, or corrosive media makes carbon steel an unsuitable choice. Grade 316 stainless steel offers enhanced resistance to chlorides and acidic environments compared to Grade 304, making it a common specification in coastal installations, chemical handling lines, process piping, and sanitary or potable water systems. The Schedule 80 wall thickness supports higher working pressures and provides additional mechanical durability in tight or vibration-prone installations.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in chloride and acidic environments
• Seamless construction eliminates weld seams, improving pressure uniformity and structural integrity
• Schedule 80 wall thickness rated for higher working pressures than Schedule 40
• 1-1/2 inch pipe size fits standard NPT threaded fittings and valves
• Suitable for potable water, chemical, process, and HVAC hydronic piping applications

Compatibility

Designed as an OEM-style replacement or new-install fitting compatible with standard 1-1/2 inch NPT threaded pipe systems requiring Schedule 80 Grade 316 stainless steel components.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC codes and local jurisdiction requirements. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant rated for stainless steel and the intended service media. Avoid over-tightening threaded connections, as stainless steel threads are susceptible to galling without proper lubricant or anti-seize compound.
