NDS 64P01 6 in by 4 in Tee Hub - Low-Turbulence 90-Degree Branch

Our review of the NDS 64P01 PVC Tee Hub finds it best suited for contractors and homeowners installing non-pressurized underground sewer and drainage lines who need a reliable 90-degree branch with minimal turbulence. The bottom line: this Tee adds a sweeping T intersection to 6 in sewer and drain runs with a 4 in branch, and its solvent-weld Hub connections make it straightforward to install while maintaining a watertight pipeline. For anyone building or repairing stormwater or sewer drainage where smooth flow and compatibility with common S&D pipe are priorities, this fitting delivers a simple, durable solution.

Key Features

• Sweeping T intersection: Designed to create a smooth T intersection that reduces turbulence where three pipes meet, helping maintain flow through the network.
• 90-degree branch to 4 in: Provides a right-angle branch to 4 in Sewer & Drain pipe, allowing a smaller lateral connection without sharp corners that trap debris.
• Hub x Hub x Hub solvent-weld: PVC construction intended for solvent-weld Hub connections gives a permanent, watertight joint for underground use.
• Compatibility with S&D standards: Works with Sewer and Drain pipe meeting ASTM D 2729, 3034, 2751 and F 810, ensuring fit with common non-pressurized drainage systems.
• Integrates with drainage components: Connects to channel drain outlets, Flo-Well dry well systems, drainage grates, and pop-up emitters that make 4 in or 6 in S&D connections.
• Low-pressure suitability: Intended for non-pressurized underground applications with a low maximum working pressure, suitable for typical stormwater and sewer gravity flows.

Who It's For

The NDS 64P01 is a good pick for landscapers, plumbing contractors, and experienced DIYers installing or repairing underground sewer and drain lines who need a sturdy 6 in run with a 4 in branch. It is particularly useful where a sweeping intersection is preferred to reduce turbulence and simplify cleanouts.

Those who should look elsewhere include projects requiring DWV Schedule 40 fittings or pressurized piping, since this tee is not compatible with DWV Schedule 40 per ASTM D 2665 and is intended for non-pressurized S&D systems only.

Pros & Cons

Pros

• Simple solvent-weld Hub installation produces a watertight connection for underground S&D piping.
• Sweeping T design reduces turbulence and makes routine cleaning and flow management easier.
• Compatible with common S&D pipe standards and a range of drainage components for flexible use on site.
• Durable PVC material suited to long-term underground service in gravity drainage systems.

Cons

• Not compatible with DWV Schedule 40 pipe and fittings, so it cannot be used where those standards are required.

Our Verdict

The NDS 64P01 Tee Hub is a practical choice for anyone installing gravity sewer and storm drainage who needs a reliable 6 in run with a 4 in branch and a smoother intersection to reduce turbulence. Its solvent-weld PVC construction and compliance with common S&D standards make it good value for site installations where DWV Schedule 40 is not required.

Frequently Asked Questions

Can this tee be used with Schedule 40 DWV pipe?
No. The tee is not compatible with DWV Schedule 40 pipe and fittings per ASTM D 2665 and is intended for Sewer & Drain pipe meeting the listed S&D ASTM standards.

Is the connection watertight?
Yes. The fitting is PVC designed for Hub x Hub x Hub solvent-weld connections that create a permanent, watertight joint for underground use.

Can it connect to channel drains or pop-up emitters?
Yes. It is designed to work with select drainage products such as channel drain outlets, Flo-Well dry well systems, drainage grates, and pop-up emitters that make 4 in or 6 in S&D connections.
