What is PPR Plastic Union?
PPR Plastic Union is a detachable fitting used in PPR piping systems to connect pipes securely while allowing easy disassembly for maintenance.
Advantages of PPR:
1.High-Temperature Resistance
Handles hot water (up to 95°C short-term, 70°C continuous) without deformation.
Ideal for hot water plumbing and heating systems.
2.Corrosion & Chemical Resistance
Immune to rust, scaling, and electrolytic corrosion.
Resistant to acids, alkalis, and organic solvents.
3.Smooth Interior Surface
Low friction loss prevents scaling/bacterial buildup.
Maintains water quality (suitable for potable water).
4.Lightweight & Easy Installation
1/8 the weight of metal pipes; reduces labor/time.
Joined via heat fusion welding, creating leak-proof monolithic connections.
5.Durability & Longevity
Service life ≥ 50 years under standard conditions.
Low thermal conductivity minimizes heat loss.
6.Eco-Friendly & Safe
Non-toxic, compliant with potable water standards (e.g., FDA, WRAS).
Recyclable and energy-efficient to produce.
7.Low Noise Transmission
Dampens water flow noise compared to metal pipes.
Features:
1. Material:
• Made from PPR (Polypropylene Random Copolymer) – offering chemical resistance, durability, and suitability for hot/cold water systems.
2. Dimensions:
• Available in standard sizes: 20mm to 110mm.
• Custom sizes and colors (e.g., white, green, black) available upon request.
• Pressure rating: S2.5 (equivalent to PN25, supporting 25 bar at 20°C).
Functions:
- Creates a demountable, leak-proof connection between two PPR pipes of the same diameter (20-110mm, customizable).
- Allows easy disassembly/reassembly for maintenance using its threaded nut, without cutting pipes.
- Seals pressure-tight via a compression gasket (standard for unions).
- Rated for pressure class S2.5.
Applications
- Plumbing Systems: Connecting PPR pipes in hot & cold water lines within buildings.
- HVAC Installations: Joining pipes in heating, ventilation, and air conditioning systems.
- Industrial Fluid Transport: Demountable connections for various compatible liquids in industrial settings.
- System Maintenance Points: Locations requiring future access, inspection, or component replacement.
