The 13mm GI 3-Way Tee 25x20x20 is a critical T/Y-branched pipe fitting crafted from high-grade galvanized malleable iron, engineered to connect pipes of varying diameters (25mm main lines, 20mm branch lines) in plumbing, fire protection, and industrial systems. Unlike standard straight fittings, this 25x20x20 GI tee features a 90-degree branch design that splits fluid or gas flow without disrupting pressure, making it essential for scenarios where pipeline direction and size adjustment are both required. Its galvanized surface treatment sets it apart from non-protected fittings, adding a barrier against environmental wear— a key advantage for long-term use in damp or exposed settings. As a plumbing 3-way connector, it eliminates the need for multiple adapters, streamlining installation and reducing leak risks in residential, commercial, and industrial applications.
The hot-dip galvanized or electro-galvanized finish of this 3-way tee creates a durable zinc layer that resists rust, oxidation, and chemical damage. This makes the galvanized malleable iron 3-way tee ideal for outdoor piping, basement plumbing, or water treatment systems where moisture exposure is constant.
Engineered to meet rigorous international benchmarks—including ISO 5922, EN 1562:1997, DIN 2950, and ANSI/ASME B16.3—the 25x20x20 GI tee ensures compatibility with piping systems worldwide. Compliance with these standards also validates its safety, reducing the risk of system failures in high-stakes applications like fire protection.
Equipped with BSP (British Standard Pipe) or NPT (National Pipe Taper) threads, the 13mm GI 3-way connector installs quickly with basic tools. Tapered threads form a tight seal when paired with standard thread sealant or PTFE tape, minimizing labor time and eliminating the need for specialized equipment.
Constructed from malleable iron—a material prized for its ductility and impact resistance—the 3-way tee maintains structural integrity in high-pressure systems. This durability makes the high-pressure GI tee suitable for fire sprinkler lines, industrial fluid transport, and HVAC refrigerant pipelines.
The T/Y-branch structure of the fire protection tee fitting allows for flexible 90-degree flow direction changes, adapting to tight spaces (e.g., wall cavities, under-floor piping) where standard fittings might not fit. This versatility expands its use across diverse piping layouts.

In wet or dry fire suppression setups, the fire protection tee fitting links 25mm main water lines to 20mm sprinkler branch lines. Its high-pressure tolerance and UL/FM certifications ensure reliable water distribution during emergencies, meeting building safety code requirements.
For homes, offices, or retail spaces, the plumbing 3-way tee splits water flow from main pipelines to smaller branch lines that supply sinks, toilets, or showers. The 25x20x20 reducing design maintains consistent water pressure across multiple fixtures.
In manufacturing or chemical facilities, the industrial 3-way tee fitting handles the transport of liquids or gases between main lines and secondary pipes. Its galvanized finish resists corrosion from industrial fluids, extending the fitting’s service life.
Heating, ventilation, and air conditioning systems use the HVAC 3-way tee to distribute water or refrigerant between pipes of different sizes. The fitting’s ability to withstand temperature fluctuations ensures stable performance in heating or cooling loops.
• Base material: Premium malleable iron (compliant with ANSI/ASTM A197 for strength)
• Surface treatments: Hot-dip galvanized (maximum corrosion protection), electro-galvanized (smooth finish for indoor use), or natural black (cost-effective for low-moisture environments)
• Thread type: Universal BSP or NPT threads (tapered for leak-proof sealing)
• Branch design: T/Y shape for 90-degree flow direction, with precision-machined interiors to reduce turbulence
• Size configuration: 25mm (main line) × 20mm (branch line) × 20mm (branch line)
• Certifications: FM, UL, CE, ABNT, SNI (validating safety for global markets)
• Standards alignment: ISO 7-1 (thread dimensions), EN 10242 (malleable iron fittings), DIN 2950 (industrial fitting specs)
While the galvanized malleable iron 3-way tee is corrosion-resistant, it is typically recommended for non-potable water systems. For drinking water applications, confirm with the supplier that the fitting meets local health standards (e.g., lead-free requirements).
Yes, the 25x20x20 GI tee is compatible with most threaded metal pipes (e.g., black iron, stainless steel) as long as the thread type (BSP/NPT) matches. Pairing it with galvanized pipes will maximize corrosion resistance.
For residential plumbing, experienced DIYers can install it with a pipe wrench and thread sealant. For industrial or fire protection systems, professional installation is recommended to meet safety codes.
First, check if the threads are properly tightened. If leaks persist, reapply thread sealant or replace the fitting— leaks often stem from insufficient sealing or damaged threads.
No, the natural black 3-way tee lacks galvanization and is prone to rust in outdoor or damp environments. Opt for hot-dip or electro-galvanized finishes for outdoor applications.
