Descrição
What is a PPR Fitting Straight Coupling?
PPR Fitting Straight Coupling joins two same-diameter PPR pipes.
It is made of 100% virgin PPR resin for safety and durability.
It creates a permanent, leak-proof joint via thermal fusion.
It has no internal barriers to block water flow.
It works for both hot and cold water plumbing systems.
It complies with ISO 15874 and GB/T 18742 standards.
It resists corrosion, scaling, and chemical damage.
It is lightweight and easy to handle during installation.
Key Features Buyers Should Focus On
Uniform wall thickness to ensure even fusion and pressure resistance.
Smooth inner surface reduces flow resistance and turbulence.
Temperature resistance: up to 95°C (203°F) continuous use.
Pressure rating: PN10 (10 bars) for standard applications.
Clear size markings for easy identification and selection.
No toxic additives, safe for drinking water contact.
Reinforced ends to prevent cracking during fusion.
How to Avoid Fusion Mistakes
Preheat the fusion machine to exactly 260°C (500°F).
Cut PPR pipes squarely with a dedicated pipe cutter.
Deburr pipe ends to remove sharp edges and debris.
Clean coupling ports and pipe ends with a dry, lint-free cloth.
Do not twist pipes while inserting them into the coupling.
Hold the joint for 10 seconds after fusion to set properly.
Allow 30 minutes of air cooling before testing for leaks.
How to Distinguish High-Quality Couplings
Check for a milky white, uniform color (no streaks or discoloration).
Rub the coupling; it should have no plastic or chemical odor.
Inspect for smooth surfaces with no burrs or bubbles.
Verify ISO 15874 certification markings on the body.
Avoid couplings with thin walls or uneven thickness.
High-quality PPR melts cleanly with minimal smoke when burned.
Common Applications
Extending straight PPR pipe runs in residential plumbing.
Repairing broken or cut PPR pipes in walls or floors.
Connecting PPR pipes in underfloor heating systems.
Extending water lines in commercial offices and retail spaces.
Joining PPR pipes in solar water heater systems.
Connecting pipe sections in rainwater harvesting systems.
