IFAN ASTM F877 PEX Brass Sliding Female Thread Tee Fittings

Brass Sliding Female Tee Fittings: A Premium Solution for Secure and Adjustable Pipe Branching

1. Core Features & Advantages

• Material & Durability:
  Crafted from high-quality brass (e.g., lead-free CW617N or HPb58-3A), these fittings resist corrosion, scaling, and chemical degradation, ensuring longevity in potable water, heating, and industrial systems.
  • Certifications: Compliant with ISO 9001, CE, GS, NSF, ASTM, and ANSI standards, meeting global safety and quality benchmarks.
• Adjustable Design:
  The rotating nut allows flexible orientation, simplifying installation in tight spaces (e.g., pipe wells or trenches). No welding or specialized tools are required, reducing labor time by up to 75% compared to traditional methods.
• Leak-Proof Performance:
  Engineered for high-pressure (up to 2 MPa) and high-temperature (up to 95°C) environments, the embedded sealing mechanism ensures airtight connections even under thermal cycling.

2. Technical Specifications

• Size Range:
  Available in diameters from Ø12mm to Ø25mm (e.g., 16mm, 25mm fittings), compatible with PEX, PE-RT, PB, and copper pipes.
  • Threaded Options: FNPT (Female National Pipe Taper) tees support sizes up to 2 inches for larger systems.
• Operating Conditions:
  • Temperature: -20°C to 95°C (short-term peaks up to 110°C).
  • Pressure: Rated for 1.6–2.0 MPa, suitable for residential and commercial applications.

3. Applications

• Residential Plumbing:
  Branching cold/hot water lines, boiler connections, and radiator systems.
• Commercial & Industrial:
  Chemical transport, compressed air networks, and HVAC refrigerant lines.
• Underfloor Heating:
  Distributing hot water loops in floor heating systems.

4. Installation & Maintenance

• Steps:
  1. Cut pipes to length with a clean, square end.
  2. Slide the tee fitting onto one pipe.
  3. Align and insert the second pipe into the opposite socket.
  4. Hand-tighten the rotating nut, then use a wrench for final adjustment (avoid over-tightening).
• Maintenance:
  • Routine Inspection: Check for leaks or loosening annually.
  • Cleaning: Wipe with a mild soap-and-water solution and a soft cloth. For tarnish, use a brass-safe polish (e.g., Brasso).
  • Corrosion Prevention: Ensure proper drainage to avoid standing water.
