Plug 3/4″ RAKtherm PPRc

 “Plug 3/4″ RAKtherm PPRc PN 25” fitting are not directly available in the search results. However, I can provide you with comprehensive information about this fitting type based on RAKtherm PPRc PN 25 specifications and standard PPRc plug fittings.

What This Fitting Is

A Plug 3/4″ RAKtherm PPRc PN 25 is a closing fitting used to terminate or seal a PPRc pipe system. It’s imported from UAE (Ras Al Khaimah) by Gulf Plastic & Converting Industries under the RAKtherm brand.

Important clarification: The “3/4″” designation typically refers to the thread size (if it’s a threaded plug adapter), not the pipe socket size. Standard PPRc plugs are sized by pipe diameter (20mm, 25mm, 32mm, etc.). A 3/4″ plug would likely connect to a 25mm PPRc pipe (which corresponds to 3/4″ nominal pipe size).

Description & Function

This plug fitting serves as a terminating/closing component in PPRc piping systems:

• Purpose: Seals the end of a pipe or fitting to stop water flow

• Connection Type: Socket fusion welding (PPRc side)

• Application Areas:

  • Hot and cold potable water supply systems

  • HVAC heating/cooling loops

  • Boiler connections, radiator networks

  • Residential, commercial, hospital, hotel plumbing

  • Swimming pools, gyms water filtration

Key Benefits:

• Corrosion-resistant (unlike metal plugs)

• 100% recyclable, environmentally friendly

• Hygienic, food-grade material suitable for drinking water

• Smooth internal bore reduces pressure loss

• Leak-proof fusion-welded connection

Installation Guide

Socket Fusion Welding Steps:

1. Prepare the Pipe

   • Cut the PPRc pipe squarely using a professional pipe cutter

   • Deburr/chamfer the pipe edges

   • Clean and dry the pipe end

2. Set Up Welding Equipment

   • Preheat socket fusion welding machine to 260°C

   • Use appropriate heating dies for 25mm fittings

3. Heating Time (for 25mm PN 25):

   • Heating duration: 6–7 seconds

   • Changeover time: 4–6 seconds

4. Joining

   • Mark insertion depth on the pipe

   • Insert pipe and fitting into heating dies simultaneously

   • After heating, quickly but carefully push pipe into plug socket straight (no twisting)

   • Hold without rotation for 5–10 seconds

5. Cooling

   • Allow joint to cool fully for 4 minutes (do NOT cool with water)

   • Total cooling time: ~4–6 minutes

   • Wait 1–2 hours before pressure testing

6. Pressure Test

   • Test system under pressure to ensure no leaks

For Threaded Version (if 3/4″ threaded plug):

• Apply Teflon tape (5–7 wraps clockwise) on male threads only

• Screw into female threaded component hand-tight

• Tighten 1–2 turns with wrench (on hex portion, not PPR body)

• Max torque: ~30–40 Nm for 3/4″

Usage & Applications

Primary Applications:

When to Use PN 25 (vs PN 20/PN 16):

• Higher pressure rating – suitable for high-pressure systems

• High-temperature applications – better performance at elevated temperatures

• Main supply lines – primary water distribution where pressure is higher

System Compatibility:

• Compatible with all RAKtherm PPRc pipes (25mm to 110mm)

• Works with third-generation food-grade PPRc systems

• Accepts chemicals commonly found in water systems

Additional Information

Quality Assurance:

• 10-year guarantee from date of purchase

• ISO 9001-2008 Quality Management certified

• Produced according to DIN 8077/8078 standards

Packaging:

• Typically 5 pieces per pack for 25–32mm sizes

• Weight per piece: ~0.015–0.025 kg

Distributor Contact (Pakistan):

• AR Corporation: 0322-3540656

This fitting is an essential component for terminating PPRc piping systems in high-pressure hot/cold water HVAC applications, offering superior corrosion resistance and 50+ year service life compared to traditional metal alternatives.
