What is Female Socket 32×3/4″ EG PPRc ?

 

A Female Socket 32×3/4″ EG PPR-C PN25 is a pipe fitting made of PPR-C (Polypropylene Random Copolymer) with one end designed to join a 32 mm PPR pipe and the other end featuring a 3/4″ female threaded connection (for connecting to threaded valves, appliances, faucets, pumps, etc.). It’s rated PN25, meaning it’s suitable for high-pressure applications up to approximately 25 bar.

• Material: PPR-C (Polypropylene Random Copolymer) — a durable, corrosion-resistant thermoplastic.

• Size: 32 mm socket side × 3/4″ female BSP threaded side.

• Pressure Rating: PN25 (≈25 bar) for hot/cold water and HVAC services.

  Connection Types:

  • Socket fusion to PPR pipe (32 mm).

  • Female threaded connection (3/4″) for metal or threaded components.

The “EG” typically refers to integrated brass (or metal) female threads molded into the PPR body — this gives strength and better thread engagement compared to plastic threads alone.

🧱 Material & Specifications

🏭 Material Properties

• PPR-C (Polypropylene Random Copolymer) is widely used in plumbing due to its:

  • Excellent resistance to hot and cold water.

  • Resistance to corrosion, scaling, and chemicals.

  • Non-toxic and hygienic, safe for potable water.

• Brass insert (female thread) increases mechanical strength and sealing reliability on the threaded side.

📊 Typical Specs

Note: PN25 ratings correspond to PPR systems designed for frequent hot water use and higher pressure conditions than lower PN ratings.

🔧 How It Works

This fitting achieves a hybrid connection:

1. Socket side (PPR) — this side is joined permanently to a PPR pipe by heat fusion (socket fusion welding). The pipe and fitting are heated and fused to form a seamless joint.

2. Threaded side (3/4″ female) — this end receives a male threaded fitting, valve, faucet, pump connection, or other equipment.

This combination lets you easily link plastic PPR piping to metal components without separate adapters.

🛠️ Installation Guide (Typical)

🪛 Tools You’ll Need

• PPR pipe cutter

• Socket fusion welding machine with appropriate size heater heads

• Marker

• Thread sealant (PTFE/Teflon tape) or suitable pipe dope

Step-by-Step

1. Cut and Prep the Pipe

   • Cut the 32 mm PPR pipe cleanly and squarely.

   • Remove burrs and debris.

2. Mark Insertion Depth

   • Determine how far the pipe should enter the socket. Mark that point.

3. Heat Fusion Welding

   • Heat the pipe end and the socket fitting simultaneously using the fusion machine.

   • Insert the pipe into the socket fully and hold still for ~5–10 seconds.

   • Cool Down

   • Allow the joint to cool to ensure a very strong, permanent union.

4. Thread Connection

   • Apply PTFE tape to the male threads of the valve or threaded device.

   • Screw it into the female 3/4″ thread until tight and leak-proof.

5. Pressure Test

   • It’s good practice to pressurize the system (hydrostatic test) to check for leaks before final commissioning.

💧 Usage & Applications

This type of fitting is very common in plumbing and HVAC due to its versatility:

🏠 Domestic & Commercial Water Systems

• Hot and cold potable water distribution.

• Connections to fixtures, faucets, valves, and water heaters.

🔥 HVAC Systems

• Linking PPR water supply lines to boilers, pumps, manifolds, or metal valves.

🏢 Industrial & Commercial Installations

• Heat transfer loops, chilled water lines, hydronic heating.

• Systems requiring corrosion-resistant non-metallic piping but occasional metal connections.

🛠️ Why Choose PN25 Rated PPR?

• Higher allowable pressure makes it suitable where system pressures are elevated (e.g., multistory buildings, HVAC loops).

📌 Key Advantages

✔ Leak-proof piping: Heat fusion creates joints stronger than the pipe itself. 
✔ Corrosion resistance: PPR material does not rust — great for long-term water quality.
✔ Hygienic & safe: Non-toxic material suitable even for potable water.
✔ Easy transition to metal parts: Female thread insert bridges the gap between plastic pipework and threaded fittings or valves.
✔ Suitable for hot water up to ~95 °C: Excellent performance in HVAC and heating loops.

📍 Typical Standards

Products like this generally follow international PPR standards:

• DIN 8077 / 8078

• ISO 15874

These standards govern material composition, dimensions, pressure/temperature ratings and performance for PPR systems.
