When it comes to modern plumbing and heating systems, PPR (Polypropylene Random Copolymer) fittings are the top choice for professionals worldwide. They resist corrosion, high temperatures, and pressure, making them perfect for hot and cold water systems.
For even greater durability and reliability, PPR fittings with copper inserts provide reinforced connections, ideal for metal-to-plastic integrations in residential and industrial systems.
What Are PPR Fittings with Copper Inserts?
⦁ PPR fittings with copper inserts are hybrid fittings combining the flexibility of PPR with the strength of copper.
⦁ PPR body: Resistant to scaling, corrosion, and chemical damage.
⦁ Copper insert: Reinforces threaded areas for tight, leak-proof connections to metal components like valves, pumps, or radiators.
⦁ These fittings are widely used in plumbing, HVAC, and floor heating systems, ensuring safe and durable connections between plastic pipes and metal equipment.
Common Types of PPR Fittings with Copper Inserts
⦁ Female Threaded Adaptor (Internal Thread) – Connects PPR pipes to male-threaded metal parts.
⦁ Male Threaded Adaptor (External Thread) – Connects to female-threaded metal components.
⦁ Elbows and Tees with Inserts – For changing direction or connecting multiple pipes with reinforced joints.
⦁ Unions and Valves – Detachable connections for easy maintenance.
Key Advantages
🛠️ 1. Strong, Leak-Proof Connections
Copper inserts prevent cracks or leaks due to over-tightening at threaded joints.
🔥 2. High-Temperature Resistance
Handles hot water and heating systems safely, maintaining long-term stability.
🧲 3. Seamless Metal-Plastic Integration
Ideal for boilers, water meters, radiators, or manifolds.
💧 4. Corrosion & Scale Resistance
PPR prevents scaling and chemical corrosion, keeping water clean and flowing.
♻️ 5. Durability & Longevity
Proper installation ensures service life of over 50 years, making them a cost-effective choice.
🔍 Applications
⦁ Hot and cold water supply systems
⦁ Underfloor heating systems (PERT/PPR)
⦁ HVAC systems
⦁ Industrial fluid transport
⦁ Residential and commercial plumbing
⚒️ Installation Tips
⦁ Use correct welding temperature (260–270°C) for strong fusion.
⦁ Avoid over-tightening metal-threaded parts; hand-tighten first.
⦁ Apply thread seal tape or sealant for extra protection.
⦁ Support fittings properly to prevent stress on joints, especially near valves or heavy equipment.
