Asc Engineered Solutions 318901121 Cast Iron Cap 5 Inch

Product Description

The ASC ENGINEERED SOLUTIONS 318901121 is a 5-inch black cast iron cap designed to terminate or seal the end of a cast iron pipe. This fitting provides a durable, pressure-resistant closure for drainage, waste, and vent (DWV) piping systems. The black coating is applied at the factory and resists corrosion in typical underground and above-ground plumbing environments. At 11.19 pounds, the casting reflects the heavy-wall construction standard in cast iron pipe work. Licensed plumbers and pipefitters install this cap as part of rough-in and finish plumbing on residential and commercial projects.

This cap is suited for DWV applications where a cast iron pipe run must be cleanly terminated. Common install scenarios include capping unused branch outlets, closing off service openings during rough-in inspections, and permanent termination of drain or vent stacks. It is domestically manufactured, making it a practical choice for projects requiring domestic-sourced materials. The 5-inch size fits standard 5-inch cast iron pipe.

Key Features

• 5-inch fitting size for standard cast iron pipe termination
• Black factory coating for corrosion resistance
• Heavy-wall cast iron construction for durability in DWV service
• Domestically manufactured
• 11.19-pound casting weight reflects full cast iron wall thickness

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 5-inch cast iron DWV piping systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off water supply and verify the line is depressurized before fitting installation. Cast iron caps in DWV service are typically joined using no-hub couplings or hub-and-spigot lead-and-oakum methods depending on the existing pipe system. Do not use this fitting on pressurized supply lines unless the fitting is explicitly rated for that service.
