Product Description
POLYGON PERT fittings are designed for reliability and ease of installation in heating and plumbing systems. The 90° Elbows facilitate directional changes with minimal flow resistance. Couplings and Elbow provide leak-free connections, while Tees and Reducing Tees enable efficient branch distribution. All fittings feature standardized threads (ISO 228-1) and are compatible with hot-melt welding techniques. The brass construction ensures high tensile strength (≥280 N/mm²) and elongation (≥10%), making them suitable for high-pressure applications.

Quality Control Process
Material Selection
CW617N brass verified for composition and mechanical properties.
Hot Forging
Enhances structural integrity and stress resistance.
Precision Machining
CNC machining ensures dimensional accuracy (tolerance ±0.1 mm).
Annealing Treatment
Eliminates internal stress, prevents cracking.
Pressure Testing
Hydrostatic tests at 20 kg/cm² to validate leak-proof performance.
Surface Inspection
Nickel plating checked for uniformity and adhesion.
Performance Advantages
Double O-ring seals ensure zero leakage under high pressure.
Nickel plating protects against oxidation and chemical damage.
Tensile strength ≥280 N/mm² withstands mechanical stress.
Standardized threads and hot-melt compatibility reduce installation time.
≥50 years under continuous operation at 95°C.
Lead-free materials comply with drinking water standards.
Applicable Scenarios
- Radiator Heating Systems: Connecting PERT fittings pipes to radiators and boilers.
