What is Reducing Tee 90x75mm EG PPRc ?

 

Description

A Reducing Tee 90x75mm EG PPRc PN25 is a pipe fitting made from Polypropylene Random Copolymer (PPR or PPRc), a high-quality thermoplastic material. It is a reducing tee with three outlets: two larger diameters (90mm) for the main run (straight through) and one smaller branch outlet (75mm) at a 90-degree angle. This design enables branching a smaller pipe from a larger main line while preserving flow direction.

• PPRc: Polypropylene Random Copolymer Type 3, offering superior heat resistance, chemical resistance, and hygienic properties (safe for drinking water, no odor or taste transfer).
• PN25: High pressure rating of 25 bar (2.5 MPa), ideal for demanding applications.
• EG: Commonly refers to a brand series, specific marking, or “electrofusion compatible” in some regional standards (though standard PPR uses socket fusion).
• Colors: Usually green, white, or grey.

These fittings are widely used in modern plumbing systems as a superior alternative to metal pipes, providing corrosion-free, lightweight, and long-lasting performance.

Specifications

• Material: Polypropylene Random Copolymer (PP-R Type 3)
• Sizes: Main run: 90mm outer diameter × 90mm; Branch: 75mm outer diameter (often denoted as 90x75x90mm)
• Pressure Rating: PN25 (25 bar at 20°C; suitable for high-pressure systems, derated at higher temperatures)
• Temperature Range: -20°C to 95°C (short-term up to 110°C)
• Standards: Compliant with DIN 8077/8078, ISO 15874, or equivalents (e.g., DVGW, WRAS)
• Connection Type: Socket fusion (heat welding)
• Service Life: 50+ years under standard operating conditions
• Properties:
  • Hygienic and non-toxic (potable water approved)
  • Excellent resistance to chemicals, corrosion, scaling, and impact
  • Low thermal conductivity (natural insulation)
  • Smooth interior (minimal friction, high flow efficiency)

Usage and Applications

This fitting is designed for hot and cold water supply systems and HVAC applications, including:

• Potable water distribution in residential, commercial, and industrial buildings
• Heating systems (radiators, underfloor heating)
• Chilled/hot water circuits in HVAC (air conditioning, ventilation)
• Non-aggressive industrial fluids and compressed air systems

It is particularly useful in larger diameter mains (e.g., 90mm risers) where a reduced branch (75mm) is needed for secondary lines or fixtures. Not recommended for gas or highly aggressive chemicals.

Advantages:

• Rust-free and scale-resistant (unlike metal)
• Lightweight, easy to transport/install
• Reduced energy loss due to insulation properties
• Environmentally friendly and recyclable

Installation

PPR fittings like this reducing tee use socket fusion welding for permanent, homogeneous joints that are stronger than the pipe.

Step-by-Step Guide:

1. Tools Needed: PPR pipe cutter, fusion welding machine (with 90mm and 75mm sockets), deburring tool, marker, clamps.
2. Prepare Pipes: Cut pipes squarely, deburr/chamfer ends cleanly.
3. Mark Insertion Depth: Use manufacturer chart (approx. 35-40mm for 90mm; 30-35mm for 75mm).
4. Heat Welding: Set machine to ~260°C. Heat pipe and fitting simultaneously:
   • Heating time: ~30-40 seconds for 90mm; ~25-30 seconds for 75mm (follow exact brand guidelines).
5. Join: Remove from heater, align straight, insert firmly with a slight twist. Hold immobile for 30-60 seconds.
6. Cooling: Allow 10-15 minutes before handling or pressurizing.
7. Support: Use clips/supports every 1-1.5 meters.
