Whether you're working with a sanitary or stormwater system, or need compatibility across pipe types and sizes, Inserta Tee has a solution for you.

One Product Line, Three Variations

The Inserta Tee product line includes three variations: Traditional, Multifit and OneFit. Each is designed to deliver long-lasting watertight lateral connections. Here’s what they all share, and what sets them apart.

What all Inserta Tee Products Have in Common

Every Inserta Tee fitting is engineered for high performance, convenience and adaptability.

• Watertight Connections: Prevents leakage and maintains stability- withstanding harsh conditions.
• Quick, Non-Invasive Installation: Installs without adhesives or disturbing backfill, saving labor and keeping your mainline pipe base stable.
• Universal Compatibility: Adapts to any pipe size, type, or manufacturer.
• Three-Part Design: Each fitting includes a rubber sleeve, a stainless-steel band, and a PVC hub. All working together to ensure a secure, watertight seal.

Inserta Tee fittings are widely used for drainage, agriculture, sanitary and infrastructure projects.

How to Select the Best Inserta Tee for Your Job

Each configuration of Inserta Tee offers high performance and durability, but the key difference between each variation is the unique customization and versatility.

Traditional – Sanitary & Stormwater Applications

The Traditional Inserta Tee is designed for sanitary and stormwater systems. It features a custom rubber sleeve engineered to fit a specific mainline pipe type and size, ensuring a precise and watertight fit.

Best for: Systems requiring custom-fit lateral connections

Multifit – Sanitary & Stormwater Applications

The Multifit Inserta Tee is ideal for either sanitary or stormwater projects. It includes a sleeve that fits a defined range of pipe diameters, providing flexibility without sacrificing security.

Best for: Projects with varying pipe sizes or applications requiring a broader fit range across sanitary and stormwater systems

OneFit – Stormwater Applications

The OneFit Inserta Tee is the go-to option for stormwater systems. Its adjustable sleeve makes it compatible with virtually any mainline pipe size, while maintaining a fixed lateral size for consistent performance.

Best for: Stormwater applications or projects requiring maximum adaptability across pipe systems

To select the correct fitting, start with the Inserta Tee Part Selector. The tool will guide you step by step, but you’ll need to provide three key details which you can find below. With these answers, the Part Selector identifies the right Inserta Tee fitting for your project and provides specific product and hole saw information.

Application: Storm or Sanitary

Refers to the kind of infrastructure Inserta Tee will be used in. Each system has different requirements for performance.

Stormwater systems:

Return rainwater into the ground or nearby water sources as efficiently and cleanly as possible. Some instances require watertight for stormwater systems while others may not.

Sanitary sewer systems:

Move graywater and black water to the nearest water treatment facility before it is returned to the environment.  Due to the nature of the conveyance within sanitary sewer systems, watertight connections are the industry standard because they are designed to prevent leakage into the soil as well as preventing additional groundwater from entering the treatment system.

Mainline pipe: Type and Size

Refers to the host pipe Inserta Tee is installed into.

Type:

The material of the mainline pipe or structure. Inserta Tee can connect to any known mainline material type.

Some examples include corrugated high-density polyethylene (HDPE), corrugated high-density polypropylene (HDPP), SDR35 polyvinyl chloride (PVC), SDR26 heavy wall polyvinyl chloride (PVC), reinforced concrete pipe, reinforced concrete structures, C900 polyvinyl chloride (PVC), Sch40 polyvinyl chloride (PVC), ductile iron, clay, solid wall polyethylene, cured in place liner pipe, fiberglass manhole and more.

 Size:

Diameter of the mainline pipe or structure.
 

The lateral pipe: Type and Size

The new pipe connection into the mainline pipe.

Type:

Indicates the material used for the lateral pipe. Inserta Tee is engineered to work seamlessly with a broad spectrum of lateral options. Some examples include corrugated high-density polyethylene (HDPE), corrugated high-density polypropylene (HDPP), SDR35 polyvinyl chloride (PVC), SDR26 heavy wall polyvinyl chloride (PVC), C900 polyvinyl chloride (PVC), Sch40 polyvinyl chloride (PVC), iron pipe size (IPS), and ductile iron.

Size:

Diameter of the lateral pipe.

Whether it’s stormwater or sanitary applications, Inserta Tee delivers exceptional versatility and reliable performance for secure, watertight connections. Designed to meet the demands of modern infrastructure, it simplifies installation, reduces labor costs, and ensures long-term durability across a wide range of pipe materials and sizes. Inserta Tee is the trusted solution that adapts to your needs, without compromising quality or efficiency.
