Inquiry
The press tee is a type of stainless steel press-fitting pipe fitting, mainly used for branching and diverting thin-walled stainless steel pipelines. It relies on a dedicated pressing tool to squeeze the end of the fitting, causing the fitting and the pipe to interlock tightly, and achieves a sealed connection with EPDM or HNBR sealing rings—no welding or thread cutting is required throughout the entire process. The main body material is commonly 304 or 316L stainless steel, featuring corrosion resistance, hygienic compliance, and a long service life. The product is available in two main configurations—equal-diameter and reducing—and is compatible with national standard thin-walled stainless steel water pipes. It is widely used in drinking water, purified water engineering, gas, HVAC, pharmaceutical, food, and building water supply and drainage pipelines. The press connection method offers fast construction speed, and the joints are resistant to vibration and pull-out, with stable sealing performance and low risk of leakage. The Guojie brand offers a variety of specifications and supports OEM/ODM customization to meet engineering and foreign trade requirements.

A press-fit tee is a key branching fitting in thin-walled stainless steel piping systems, used for main pipe branching, line diversion, or reducing connections. It adopts press-fit connection technology, which uses special tools to radially compress and lock the fitting and pipe together, requiring no welding or threading, enabling fast installation and reliable connections. The product body is made of 304 or 316L stainless steel, with a smooth inner wall that resists scaling and meets food-grade sanitary requirements. The sealing ring is made of EPDM or HNBR rubber, which is heat-resistant and aging-resistant, ensuring long-term sealing performance. Press-fit tees are widely used in piping systems requiring high cleanliness, such as drinking water, purified water, HVAC, food, and pharmaceutical applications, and are a mainstream choice for modern building water supply and drainage and industrial piping.
The core advantage of the press-fit tee lies in its weld-free installation method and reliable sealing performance. The double-press structure permanently interlocks the fitting with the pipe, providing resistance to vibration and pull-out, effectively preventing leakage. The 304/316L stainless steel material ensures corrosion resistance and hygiene, making it suitable for drinking water systems. The product has a smooth inner wall, low water flow resistance, resistance to bacterial growth, and a long service life. In addition, the installation process involves no open flames and no welding slag, keeping the construction environment clean and making it suitable for locations with high safety requirements. We offer a variety of specifications and customization services to meet different project needs.
Press-fit tees are suitable for a variety of clean piping scenarios. Civil applications include domestic water supply and hot water systems in high-end residences, villas, hotels, schools, and hospitals. Industrial applications cover sanitary-grade conveying pipelines in food factories, pharmaceutical plants, purified water plants, and similar facilities. Public works can use them in municipal direct drinking water, secondary water supply renovation, and other projects. Additionally, they can be used in HVAC circulating water systems. The product material is safe, non-toxic, and rust-free, making it especially suitable for locations with high water quality requirements.
Press-fit tees are available in both equal-diameter and reducing configurations, with standard sizes ranging from DN15 to DN100; specific dimensions can be customized based on project requirements. The body material can be 304 or 316L stainless steel, and the sealing ring material is EPDM or HNBR. Pressure ratings of PN16 and PN25 are available, with temperature resistance up to 120°C. The product complies with standards such as Chinese national standard GB/T 19228 or European standard EN 10312; for specific applicable standards, please contact us for confirmation. Surface treatment can be mirror polishing or matte brushing. We support non-standard customization, including special reducers, large diameters, and LOGO printing.
Press-fit tees support flexible minimum order quantities: domestic stock items require a minimum order of 1 piece, convenient for sample testing or project repair; regular engineering orders require a minimum of 50 pieces and qualify for tiered pricing; foreign trade orders require a minimum of 200 pieces and support mixed specifications in one shipment. Standard sizes (DN15-DN50) are in ample stock and ship within 24 hours; medium and large diameters (DN65-DN100) are delivered within 3-5 working days. For large-volume orders, please contact us to confirm delivery times. Packaging uses standard double-layer inner and outer protection: each piece is individually packed in a transparent bag, and the outer carton is a five-layer reinforced corrugated box. Foreign trade orders are additionally wrapped with waterproof film to ensure transport safety.
We provide comprehensive after-sales service: all press-fit tees carry a two-year warranty and lifetime technical support. Every product undergoes 100% visual inspection and pressure testing before leaving the factory to ensure zero defects. If any damage occurs during transit, we will resend replacements free of charge. We also offer free installation guidance, press-fit tool usage training, and engineering selection advice to help customers solve construction challenges. Bulk customers enjoy dedicated one-on-one account service. For customization needs, we support OEM/ODM, including non-standard dimensions, materials, surface finishes, and packaging customization. Please contact us to confirm specific configurations and quotations.
The press-fit tee uses a double-press interlocking structure combined with a food-grade sealing ring, permanently securing the fitting and pipe, so under normal use it will never leak or detach over its lifetime. We perform pressure testing before shipment to ensure sealing performance.
