Msi Products Inc A37700042.5 SS316 Pipe Nipple Sch 40

Product Description

The MSI PRODUCTS INC A37700042.5 is a 316 stainless steel Schedule 40 pipe nipple sized at 0.25 inches nominal diameter by 2.5 inches in length. Threaded on both ends with NPT-conforming threads per ASME B1.20.1, it creates a secure, leak-resistant connection in piping systems that handle corrosive media, high moisture, or aggressive chemicals. The 316 alloy provides elevated resistance to pitting, crevice corrosion, and chloride attack compared to standard 304 stainless. Pipe material conforms to ASTM A312/SA312. Each piece carries full lot-code traceability and is pressure tested at the factory before shipment.

This nipple is suited for marine piping, pharmaceutical processing lines, food and beverage systems, chemical processing, and pool or water-treatment installations where chloride exposure or strict sanitation standards require a higher-grade alloy than carbon steel or 304 stainless. It is equally appropriate for general industrial plumbing where corrosion control and long service life are priorities. The compact 2.5-inch length makes it well-suited for close-quarter connections and riser applications.

Key Features

• 316 stainless steel alloy for superior resistance to chlorides, pitting, and crevice corrosion
• Schedule 40 wall thickness for high-pressure service capability
• NPT threads machined to ASME B1.20.1 for precise, reliable fit
• Pipe stock conforms to ASTM A312/SA312 material standards
• Manufactured in an ISO 9001:2000 certified facility with consistent quality controls
• Full lot-code traceability on every fitting for quality assurance
• Factory pressure tested prior to shipment

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard NPT-threaded 0.25-inch pipe systems in Schedule 40 configurations across plumbing, industrial, marine, and process-piping applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable IPC or ASME piping codes. Shut off system pressure and depressurize the line completely before removing or installing any threaded fitting. Apply a thread sealant rated for stainless steel and the media being conveyed; avoid over-tightening, which can gall stainless threads. Use a pipe wrench or strap wrench appropriate to the fitting size and material to avoid surface damage.
