Carrying drain, waste, and vent flow in a building plumbing system, this 4" no-hub cast iron pipe is a 10-foot length of hubless soil pipe joined with no-hub couplings and band clamps rather than bell-and-spigot hubs. Cast iron density makes it the quiet choice for DWV stacks and branches -- it dampens the sound of rushing water far better than plastic -- and it resists fire, heat, and crushing for a durable, code-approved drainage system. The plain hubless ends slip into a neoprene-gasketed coupling for a fast mechanical joint. At 4" diameter, it suits main stacks and building drains in commercial and multi-family construction.
Key Features:
- Quiet Cast Iron DWV -- Dense cast iron dampens the sound of draining water far better than plastic.
- No-Hub (Hubless) Ends -- Plain ends join with no-hub couplings and band clamps for fast mechanical joints.
- Fire & Heat Resistant -- Cast iron resists fire, heat, and crushing for a durable system.
- 4" Diameter, 10' Length -- Full-length run sized for main stacks and building drains.
- Code-Approved Drainage -- A proven material for commercial and multi-family DWV systems.
Where to Use:
- DWV plumbing -- Running main drain, waste, and vent stacks and building drains.
- Commercial & multi-family -- Quiet drainage in buildings where noise matters.
- Building construction -- Durable soil pipe for new work and repair.
