Asc Engineered Solutions 818900847 Malleable Iron Cap 3 Inch

Product Description

The ASC Engineered Solutions 818900847 is a 3-inch black malleable iron cap used to close the end of a threaded pipe. This fitting threads onto the male end of a pipe to provide a secure, permanent or semi-permanent termination point. It is manufactured from malleable iron with a black coating, offering durability in moderate-corrosion environments. Plumbers, pipefitters, and mechanical contractors install this type of cap on gas, water, and industrial piping systems where a threaded end must be sealed. The 3-inch size suits main distribution lines and larger branch connections in commercial and residential applications.

This cap is suited for use on threaded black iron piping systems, including natural gas supply lines, compressed air distribution, and general-purpose industrial piping. It provides a clean, flush termination at line ends, test ports, or capped-off branches during system installation or modification. Mechanical and plumbing contractors commonly stock caps of this size for rough-in work and system pressure testing.

Key Features

• Malleable iron construction provides strength and resistance to impact and vibration
• Black coating suitable for gas and industrial pipe applications
• 3-inch threaded fitting for use on standard NPT-threaded pipe ends
• Closes off pipe ends cleanly for pressure testing or permanent termination
• Import construction offers a cost-effective replacement or spare fitting option

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3-inch threaded black malleable iron piping systems.

Installation Notes

Licensed plumbers and pipefitters typically install malleable iron caps on threaded pipe systems. Shut off and depressurize the line completely before removing or installing any threaded fitting. Apply appropriate thread sealant or PTFE tape to NPT threads before threading the cap on by hand, then tighten with a pipe wrench. Follow all applicable local plumbing and mechanical codes, including IFGC requirements for gas piping systems.
