Description
Product Overview
The NIBCO Fig No U5811 is a precision‑engineered sanitary tee hub designed for demanding industrial and scientific plumbing applications. Constructed from ABS‑DWV (Acrylonitrile Butadiene Styrene – Drain, Waste, Vent) material, this fitting delivers outstanding chemical resistance, corrosion protection, and consistent performance across a broad temperature spectrum. Its three‑opening configuration enables versatile branching of pipework, while the hub ends are specifically shaped to accept male unthreaded pipes or fittings, simplifying the solvent‑weld process and reducing installation time.
Measuring 3 inches by 3 inches by 2 inches, the hub provides ample flow capacity without sacrificing a compact footprint. The interior surface is finished to a smooth, low‑friction standard, minimizing turbulence and preventing material buildup that could compromise system efficiency. Certified to ASTM D2661 and D3311, the product meets rigorous industry standards for sanitary fittings, ensuring reliability in pharmaceutical, food‑processing, and water‑treatment environments.
Beyond its technical specifications, the Fig No U5811 benefits from NIBCO’s long‑standing reputation for quality manufacturing. Each unit undergoes strict quality‑control inspections, guaranteeing dimensional accuracy and consistent material properties. The lightweight nature of ABS‑DWV reduces handling effort and shipping costs, while still delivering the durability required for high‑pressure applications.

Usage
This sanitary tee hub excels in a variety of real‑world scenarios. In pharmaceutical manufacturing, where sterility and cleanability are paramount, the smooth interior finish and chemical‑resistant composition prevent contamination and facilitate routine cleaning cycles. In food‑processing plants, the hub’s corrosion‑resistant ABS‑DWV material withstands aggressive cleaning agents and high‑temperature sanitizing procedures.
Utility and municipal water systems also benefit from the Fig No U5811’s robust design. The hub’s ability to join multiple pipe sections with a single solvent‑welded joint reduces the number of connections, decreasing potential leak points and simplifying system maintenance. Its compatibility with standard 3‑inch pipe sizes makes it a versatile choice for retrofits and new installations alike.
Installation technicians appreciate the hub’s user‑friendly design. The hub ends accept male unthreaded pipes without the need for additional adapters, and the solvent‑weld process creates a strong, permanent bond that resists vibration and pressure fluctuations. This ease of assembly translates to faster project timelines and lower labor costs.

FAQ
What pipe sizes are compatible with the Fig No U5811 hub?
The hub is sized for standard 3‑inch pipe connections, making it compatible with most commercial and industrial DWV pipe dimensions used in sanitary systems.
Can this hub be used with PVC or CPVC piping?
Yes, the hub’s ABS‑DWV material is compatible with PVC and CPVC when a proper solvent‑weld adhesive is used, allowing seamless integration across different pipe materials.
Is the hub suitable for high‑temperature applications?
ABS‑DWV maintains its structural integrity and chemical resistance across a wide temperature range, typically from -40 °F to 140 °F, making it appropriate for most hot‑water and steam‑related sanitary installations.
How does the hub ensure a leak‑free connection?
The hub’s hub ends are precision‑machined to provide a tight fit for male unthreaded pipes. When combined with the correct solvent‑weld adhesive, the joint forms a permanent, leak‑free seal that resists pressure fluctuations.
What warranty does NIBCO provide for this product?
NIBCO offers a standard limited warranty covering material defects and workmanship for a period of one year from the date of purchase, backed by responsive technical support.
