1. Material and Structural Design
Brass sliding female tee fittings are engineered from high-grade CW617N or CZ108 brass alloys, renowned for their corrosion resistance, thermal stability (-20°C to 95°C continuous use), and pressure tolerance (up to 2 MPa). The design integrates a sliding mechanism with embedded EPDM seals, enabling leak-proof connections without welding or specialized tools.

Key structural features include:
- Adjustable Nuts: Allow precise alignment during installation, reducing labor time by up to 75% compared to traditional methods.
- Three-Piece Assembly: Comprising a body, retaining ring, and nut for easy disassembly and maintenance.
- Universal Compatibility: Supports PEX, PE-RT, PB, and copper pipes in sizes ranging from 16mm to 32mm (or ½” to 2” for threaded models).
2. Performance Advantages
- Thermal Cycling Resistance: Maintains integrity under repeated heating/cooling cycles, ideal for underfloor heating and radiator systems.
- Vibration Dampening: Absorbs pipe movements, preventing stress fractures in industrial applications.
- Chemical Resistance: Withstands aggressive fluids in HVAC and chemical transport systems.
3. Application Scenarios
- Residential Plumbing
- Branching cold/hot water lines in kitchens and bathrooms.
- Connecting boiler outlets to radiator networks.
- Distributing loops in hydronic floor heating.
- Commercial and Industrial Systems
- Splitting compressed air lines in manufacturing facilities.
- Diverting refrigerant flows in HVAC installations.
- Creating secondary circuits in process piping.
- Specialized Environments
- Narrow spaces (e.g., pipe trenches, ceiling voids) due to compact design.
- Temporary setups requiring repositioning (e.g., event plumbing).
4. Installation Best Practices
- Pipe Preparation
- Cut pipes squarely using a dedicated cutter to avoid debris.
- Deburr edges to prevent seal damage.
- Connection Process
- Slide the tee onto the first pipe, align branches, and insert the second pipe.
- Hand-tighten the nut, then use a wrench for final adjustment (torque: 15–20 Nm).
- Pressure Testing
- Gradually increase system pressure to 1.5x the operating level.
- Inspect joints with soapy water for bubbles.
5. Maintenance and Troubleshooting
- Annual Inspection: Check for loosening or corrosion. Tighten nuts if necessary.
- Seal Replacement: If leaks persist, replace EPDM gaskets with OEM-specified parts.
- Lubrication: Apply silicone-based grease to threads before reinstallation.
6. IFAN Product Line Highlight (Optional Brand Reference)
