Grooved coupling tee, also known as grooved tee, belongs to the grooved pipe fitting series. It realizes branch pipe connection through the groove formed by pipe grooving, matched with couplings and rubber sealing rings, requiring no welding and no threading throughout the entire process, making installation fast and safe. The product body is mainly cast from QT450-10 ductile cast iron, and stainless steel material can be selected for certain working conditions to enhance corrosion resistance. The sealing ring uses imported EPDM rubber, which is resistant to high temperatures and aging, ensuring long-term zero leakage. This product is mainly applied in piping systems such as fire sprinkler systems, fire water supply, domestic water supply and drainage, and HVAC circulating water, achieving branch diversion from the main pipe to branch pipes. Structurally, it is divided into straight tees, reducing tees, and mechanical tees, among which the mechanical tee can be directly connected by opening a hole on the side without cutting the main pipe, making it especially suitable for renovation without stopping water supply and for adding branches to existing old pipeline networks. The product is compatible with grooved and rolled pipes such as galvanized steel pipes and seamless steel pipes, and is widely used in fire protection piping projects for factories, shopping malls, underground parking garages, and buildings, meeting fire protection acceptance standards. We provide various specifications and customization services; welcome to contact us to confirm specific configurations.

| Main Material | QT450-10 Ductile Iron (Stainless Steel Optional) |
Grooved coupling tee is a core branch pipe fitting in the grooved pipe fitting series, used to branch off from the main pipeline to achieve fluid diversion or confluence. It relies on the groove formed after pipe grooving, combined with couplings and rubber sealing rings for connection, requiring no welding and no threading throughout the entire process, making installation convenient and safe. The product body is mostly cast from QT450-10 ductile iron, and stainless steel material can be selected for some working conditions to enhance corrosion resistance. The sealing ring uses imported EPDM rubber, which is high-temperature resistant and anti-aging, ensuring long-term zero leakage. This product is widely used in fire sprinkler systems, fire water supply, water supply and drainage, HVAC circulating water and other pipeline systems, and is compatible with grooved pipes such as galvanized steel pipes and seamless steel pipes. Structurally, it is divided into straight tees, reducing tees, and mechanical tees, among which the mechanical tee can be directly opened and side-connected without cutting the main pipe, making it especially suitable for renovation without water shutdown and for adding branches to old pipe networks.
The biggest advantage of this grooved tee is that it requires no welding, no threading, and no hot work construction, making installation safe and efficient and greatly shortening the project period. The body is made of QT450-10 ductile iron material, which has strong toughness, impact resistance, and is not prone to cracking. It is pressure-resistant and corrosion-resistant, with a service life far exceeding that of ordinary cast iron pipe fittings. Equipped with imported EPDM rubber sealing rings, the sealing performance is stable, high-temperature resistant and anti-aging, achieving long-term zero leakage. The product offers multiple structures including straight tees, reducing tees, and mechanical tees to meet different diversion needs, among which the mechanical tee can be opened and branched without stopping water flow, making it especially suitable for renovation projects. In addition, we support non-standard customization, LOGO engraving, surface treatment (hot-dip galvanizing, epoxy resin powder spraying, etc.), and can provide OEM/ODM manufacturing services to meet the personalized needs of different customers.
Grooved coupling tees are compatible with the vast majority of building and industrial pipeline scenarios. Civil scenarios cover fire sprinkler systems, fire hydrant water supply, domestic water supply and drainage, and HVAC circulating water systems in office buildings, shopping malls, hotels, residential communities, underground garages, schools, and hospitals. Industrial scenarios are suitable for factory workshops, industrial parks, warehousing and logistics parks, power plant areas, and light industry and chemical low-pressure fluid pipeline systems. Municipal scenarios are used for municipal water supply and drainage pipe networks, park pipe network renovation, old city pipeline renewal, and fire protection pipe network upgrade projects. At the same time, it is suitable for pump room pipeline diversion and central air conditioning water circulation systems. It is especially suitable for special construction scenarios such as new and old pipe network renovation and branch installation by opening holes without stopping water flow, and all scenarios comply with fire protection acceptance and engineering construction standards.

No. The grooved tee adopts coupling mechanical connection, requiring no welding, no threading, and no hot work operations. Installation is safe and compliant, making it especially suitable for places with high fire protection requirements.
A regular tee requires cutting the main pipe for connection, while a mechanical tee does not require cutting the main pipe. It can directly make an opening on the pipe for side branch connection. It is suitable for scenarios such as renovation without shutting off water flow and adding branch lines to old pipe networks, making construction more convenient.
