Asc Engineered Solutions 8700136750 Black Iron Close Nipple

Product Description

The ASC Engineered Solutions 8700136750 is a 1/4 inch Schedule 40 black iron close nipple used to create short, threaded pipe connections in gas, steam, and water piping systems. Manufactured from welded steel with a black coating applied to resist corrosion, it conforms to ASTM A53 standards for structural and pressure pipe. The close pattern means the nipple has no unthreaded center section — threads run the full length, making it the right choice when minimal spacing between fittings is required. Plumbers, pipefitters, and gas technicians install these nipples as part of assembled piping runs in both residential and light commercial applications.

This close nipple is suited for threaded pipe assemblies where space between fittings is tight or where a direct coupling connection is needed. Common install scenarios include gas supply lines, boiler piping, steam distribution, and general water service piping. The standard NPT thread profile mates with Schedule 40 fittings, valves, and couplings across a wide range of brands and configurations. Minimum order quantity is 6 pieces per order unit.

Key Features

• Close pattern — fully threaded with no bare center, minimizes fitting-to-fitting distance
• Schedule 40 wall thickness rated for standard pressure service
• Black steel coating provides corrosion resistance over bare pipe
• Conforms to ASTM A53 welded steel pipe standard
• Standard NPT thread for broad fitting compatibility
• Sold individually, minimum quantity of 6 units per order

Compatibility

Designed as a standard NPT-threaded Schedule 40 black iron nipple for use with compatible Schedule 40 pipe fittings, valves, and couplings in gas, steam, and water piping systems.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable local codes and the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) as appropriate for the service. Apply a listed pipe thread sealant or PTFE tape rated for the intended service — gas, steam, or water — before threading the nipple into fittings. Shut off and depressurize the system completely before disturbing any existing connections. Do not over-tighten threaded joints; wrench-tighten to achieve a leak-free seal without stressing the fitting.
