What is Plug 1/2″ Q-Therm PPRc ?

 

A PPR-c (polypropylene random copolymer) end plug designed to seal the end of a ½″ PPR pipe.

• Often called a dead plug or testing plug because it is commonly used to temporarily or permanently close off a line during hydrostatic pressure testing or when a branch is not yet in service.

• Belongs to Q-Therm’s PN-25 (25 bar) class fittings range, imported from UAE.

 Specifications

• Type: Plug / Dead Plug / Testing Plug

• Size: ½″ (socket type for PPR-c pipe of nominal 20 mm OD)

• Material: PPR-c (food-grade, hygienic, thermoplastic)

• Pressure Rating: PN-25 (25 bar at 20 °C; pressure derates with temperature increase)

• Temperature Range:

  • Continuous service: ~60–70 °C

  • Short peaks: up to ~95 °C

• Standards: Typically conforms to ISO 15874 / DIN standards for PPR piping systems

---

 Description / Construction

• Socket Fusion End: The plug is fused onto the end of a PPR pipe using standard socket fusion welding tools.

• No flow-through: It provides a full stop — used for either temporary closure (system testing) or permanent capping.

• Food Grade: Safe for potable water networks.

---

 Usage

1. Pressure Testing:

   • Installed temporarily on pipe ends during hydrostatic testing of hot/cold water networks before commissioning.

   • Ensures the system can be pressurized safely to check for leaks.

2. Permanent Dead End:

   • Used to permanently close unused lines, branches, or future expansion points.

3. Maintenance / Isolation:

   • Provides a sealed termination during staged installation work.

 Benefits

• Leak-proof jointing with socket fusion.

• Durable & Corrosion-free compared with metal caps.

• Lightweight & Easy Installation.

• Hygienic & Food Grade → suitable for potable water.

• Long service life (up to 50 years when operated within PN and temperature limits).

 Installation / Best Practices

1. Pipe Preparation: Square-cut and clean the ½″ PPR pipe.

2. Fusion Welding: Heat plug and pipe end with welding tool → push and hold until cool.

3. For Testing: After hydrostatic test, plug may be cut off and replaced with a proper fitting, or left in place if permanent.

4. Design Notes:

   • Ensure pressure testing follows Q-Therm guidelines (often 1.5 × design pressure).

   • Allow for thermal expansion if left permanently in system.

   • Protect exposed plugs from UV if installed outdoors.
