Msi Products Inc A39700245.0 Ss Seamless Nipple Sch 80

Product Description

The MSI PRODUCTS INC A39700245.0 is a 1-1/2-inch by 5-inch Schedule 80 seamless pipe nipple machined from 316 stainless steel with NPT threads on both ends. The seamless construction eliminates weld seams, producing uniform wall strength and a smooth internal bore for unrestricted flow. Schedule 80 wall thickness provides additional pressure capacity over standard Schedule 40 fittings. The 316 alloy adds molybdenum to the base steel, delivering improved resistance to chlorides, acids, and pitting corrosion. Plumbers, pipefitters, and industrial maintenance technicians install this nipple as a close connector between threaded fittings, valves, or equipment flanges in demanding piping systems.

This nipple is suited for high-pressure and corrosive service including marine piping, chemical processing lines, pharmaceutical process skids, and saltwater-exposed systems. The NPT thread profile conforms to ASME B1.20.1, and the base material meets ASTM A312/SA312 requirements. The fitting is manufactured in an ISO 9001:2000 certified facility and is pressure tested at the factory. Each piece carries full lot code traceability for quality assurance and documentation purposes in regulated environments.

Key Features

• 316 stainless steel alloy with molybdenum for superior chloride and acid resistance
• Seamless construction eliminates weld seams and weak points for uniform wall strength
• Schedule 80 wall thickness rated for high-pressure service
• NPT threads on both ends conforming to ASME B1.20.1 for secure, leak-resistant connections
• Manufactured to ASTM A312/SA312 material standard
• Factory pressure tested with full lot code traceability included

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/2-inch NPT threaded piping systems requiring Schedule 80 stainless steel construction.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable plumbing and mechanical codes such as the IPC. Shut off and depressurize the system fully before removing or installing threaded fittings. Apply an appropriate thread sealant or PTFE tape rated for stainless steel and the service fluid before threading the nipple into fittings. Do not over-tighten NPT connections, as stainless steel threads can gall; use a pipe wrench with controlled torque to seat the joint without damaging threads.
