Asc 4354000890 Black Steel Xh Seamless Nipple 3/8 X 5-1/2 in

Product Description

The ASC Engineered Solutions 4354000890 is a black steel seamless extra heavy (XH) pipe nipple sized at 3/8 inch by 5-1/2 inch. Manufactured to ASTM A106B standards, this nipple is designed for use in high-pressure and high-temperature piping systems where a standard-wall fitting would be insufficient. The extra heavy wall provides added strength and resistance to mechanical stress. Licensed plumbers and pipefitters typically install this type of nipple in industrial, commercial, and mechanical room applications requiring reliable, leak-free threaded connections.

This nipple is suited for use in steam, gas, oil, and water piping systems where extra heavy wall pipe fittings are specified. It is commonly installed in boiler rooms, industrial process piping, and commercial mechanical systems that demand heavier wall construction. The 3/8 inch by 5-1/2 inch sizing makes it appropriate for close-quarter connections in tight piping configurations. This is an import-sourced product, noted as nondomestic, which should be considered when domestic-only specifications are required on a project.

Key Features

• Extra heavy (XH) wall construction for high-pressure and high-temperature service
• Seamless construction per ASTM A106B for consistent wall integrity
• Black steel material provides durability in steam, gas, and hydronic piping
• 3/8 inch by 5-1/2 inch dimensions for precise fit in threaded piping assemblies
• Import-sourced; confirm project specifications before use where domestic origin is required

Compatibility

Designed as an OEM-style replacement or direct-install threaded pipe nipple for use in 3/8 inch NPT piping systems requiring extra heavy wall black steel fittings.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes, including the International Plumbing Code (IPC) and International Fuel Gas Code (IFGC) where applicable. Shut off and depressurize the system fully before removing or installing any threaded nipple. Apply an appropriate thread sealant or PTFE tape to NPT threads before assembly. Avoid over-tightening, which can crack fittings or damage threads.
