What is Tee Female 32×3/4″ Brass DADEX PPRc ?

 

The “Tee Female 32×3/4″ Brass DADEX PPRc PN 25″ is a brass transition fitting designed for connecting polypropylene random copolymer (PPRc) pipes to threaded systems in plumbing applications. It’s part of the DADEX brand, which specializes in PPR piping systems. This tee features a female threaded end (3/4” NPT or BSP, depending on regional standards) and a 32mm PPRc socket, allowing seamless integration between plastic PPR pipes and metal or threaded components. It’s rated for PN 25 (nominal pressure of 25 bar at 20°C), making it suitable for high-pressure applications like HVAC systems and hot/cold water supply lines. These fittings are corrosion-resistant, durable, and comply with standards like DIN 8077/8078 for PPR pipes.

Description

• Material: High-quality brass (typically CW617N or similar dezincification-resistant alloy) for longevity and resistance to corrosion, scaling, and chemical degradation.
• Design: A T-shaped fitting with one female threaded port (3/4″ size) and two PPRc socket ends (32mm diameter). The threaded end allows connection to valves, pumps, or metal pipes, while the PPRc ends connect to PPR piping via heat fusion welding.
• Key Features:
  • Leak-proof sealing due to precise threading and fusion welding.
  • Suitable for both hot and cold water (up to 95°C for hot water, depending on pressure).
  • Lightweight yet robust, with a smooth internal surface to minimize flow resistance.
  • Color-coded or marked for easy identification (e.g., blue for cold water, red for hot).
• Common Applications: HVAC systems (heating, ventilation, air conditioning), potable water supply, underfloor heating, and industrial piping where PPRc pipes need to interface with threaded components.

Specifications

• Dimensions:
  • PPRc Socket Diameter: 32mm (outer diameter of pipe it connects to).
  • Threaded End: 3/4″ female (internal thread; compatible with 3/4″ male NPT or BSP threads).
  • Overall Length: Typically 80-100mm (varies by manufacturer).
  • Wall Thickness: Conforms to PN 25 rating, ensuring strength under pressure.
• Pressure and Temperature Ratings:
  • Nominal Pressure (PN): 25 bar (at 20°C).
  • Maximum Working Pressure: Up to 25 bar for cold water; derates to ~10-15 bar at 95°C for hot water (per DIN standards).
  • Temperature Range: -20°C to +95°C (continuous use).
• Standards Compliance:
  • EN ISO 15874 (for PPR piping systems).
  • DIN 8077/8078 (for PPR pipes and fittings).
  • ASTM F2389 (for PPR fittings in North America, if applicable).
  • Thread Standards: NPT (National Pipe Thread) or BSP (British Standard Pipe), depending on region.
• Other Specs:
  • Burst Pressure: >50 bar (safety factor built-in).
  • Flow Rate: High due to smooth bore; minimal pressure drop.
  • Weight: Approximately 150-200g (light for installation).
  • Certifications: Often CE marked, WRAS (Water Regulations Advisory Scheme) approved for potable water.

Installation

Installation requires basic plumbing tools and follows standard PPR fusion welding and threading procedures. Always wear safety gear (gloves, goggles) and ensure the system is depressurized.

1. Preparation:

   • Cut the PPRc pipe to length using a pipe cutter for a clean, square end.
   • Deburr the pipe edges and clean with a pipe cleaner to remove debris.
   • Ensure the fitting and pipe are dry and free of contaminants.

2. Fusion Welding (PPRc Ends):

   • Use a PPR welding machine with a 32mm socket die.
   • Heat the fitting’s PPRc sockets and pipe ends to 260-280°C for 5-10 seconds (time varies by tool).
   • Insert the pipe into the socket without twisting, holding for 10-15 seconds to cool and set. Avoid over-heating to prevent deformation.

3. Threaded Connection (Female End):

   • Apply thread sealant (e.g., Teflon tape or pipe dope) to the male thread of the connecting component (valve, pump, etc.).
   • Screw the male thread into the female 3/4″ end by hand, then tighten with a wrench (1-2 turns) to achieve a leak-proof seal. Do not over-tighten to avoid thread damage.

4. Testing:

   • Pressurize the system gradually and check for leaks using soapy water or a pressure tester.
   • Allow the fusion joints to cure for 24 hours before full operation.

5. Tips:

   • Work in a well-ventilated area; PPR fumes are minimal but avoid inhalation.
   • For underground or concealed installations, use appropriate supports to prevent stress on joints.
   • Consult local plumbing codes (e.g., UPC or IPC in the US) for specific requirements.

Usage

• Primary Use: As a transition fitting in PPRc piping systems for HVAC (e.g., connecting radiators or boilers) and water supply lines (e.g., linking to faucets, showers, or pumps). It bridges plastic PPR pipes with metal components, ideal for retrofits or mixed-material systems.
• Advantages: Reduces installation time compared to all-metal systems, resists corrosion better than steel, and handles thermal expansion well. Suitable for residential, commercial, and light industrial settings.
• Maintenance: Inspect periodically for leaks; no regular maintenance needed if installed correctly. Compatible with common fluids like water, glycol mixtures (for heating), and non-aggressive chemicals.
• Limitations: Not for use with highly acidic or alkaline fluids, or temperatures exceeding 95°C. Avoid direct burial without protection against soil stress.
• Safety Notes: Ensure PN 25 rating matches system pressure to prevent failure. For potable water, confirm WRAS or equivalent approval.
