Material & Color Coding:

• uPVC (Unplasticized Polyvinyl Chloride): High rigidity, structural integrity, and long-term durability.

• Color Coding:

  • Orange (Terracotta): Designed for underground and drainage applications with standards compliance.

  • White: Typically used for general potable water and pressure systems.

Standards Compliance:

• Orange (Terracotta) uPVC Couplings:

  • ISO 3633: Unplasticized PVC fittings for sewerage and drainage systems.

  • ISO 4435: Specifications for PVC pressure and drainage piping systems.

• White uPVC Couplings: General fittings compliant with standard uPVC specifications for potable water and pressure applications.

Design & Function:

• Standard Coupling (Register Coupling): Provides a secure, permanent connection, ensuring proper alignment and uninterrupted flow.

• Repair Coupling (Slip Coupling): Features extended sockets without central stops, allowing the fitting to slide along the pipe for quick repair or replacement.

Performance Characteristics:

• Pressure Ratings: Dependent on material and application type (pressure or drainage).

• Temperature Range: Suitable for standard uPVC operating conditions up to ~60 °C.

• Sealing: Compatible with solvent cement for secure, leak-free joints.

• Service Life: Over 50 years under normal design and operating conditions.

Applications:

• Potable water supply networks (white couplings).

• Drainage, waste, and vent (DWV) systems (orange/terracotta couplings).

• Underground and above-ground infrastructure piping.

• Industrial and utility pipelines requiring reliable flow connections.

Installation:

• Standard Couplings: Solvent cemented for permanent, aligned joints.

• Repair Couplings: Slide over the prepared pipe section and bonded for rapid restoration of service.

Key Benefits:

• Durable and corrosion-resistant for long-term performance.

• Color-coded for easy identification of indoor and outdoor or pressure and drainage applications.

• Quick installation and repair, minimizing downtime.

• Compliant with ISO standards for high-quality, reliable piping systems.
