Design & Function:

• Standard Coupling (Register Coupling): Provides a secure, permanent connection between two PVC pipes, ensuring alignment and uninterrupted flow.

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

Material & Color Coding:

• PVC (Polyvinyl Chloride): Rigid, corrosion-resistant, and mechanically strong.

• Color Coding:

  • White: Schedule 40, typically used for standard pressure and non-pressure applications.

  • Gray: Schedule 80, designed for higher-pressure systems requiring greater wall thickness and strength.

Standards Compliance:

• ASTM D 2466: Schedule 40 pressure fittings.

• ASTM D 2467: Schedule 80 pressure fittings.

• ASTM D 2665: Drain, waste, and vent (DWV) fittings.

Performance Characteristics:

• Pressure Ratings: Dependent on schedule (SCH 40 or SCH 80) and pipe size.

• Temperature Range: Continuous operation up to ~60 °C.

• Sealing: Compatible with PVC solvent cement for permanent, leak-free connections.

• Service Life: Over 50 years under standard operating conditions.

Applications:

• Potable water supply and distribution.

• Drainage, waste, and vent (DWV) systems.

• Industrial and utility piping networks.

• Pipeline repair and extension without system redesign.

Installation:

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

• Repair Couplings: Slide over prepared pipe sections and bond with solvent cement for rapid restoration of service.

Key Benefits:

• Maintains flow continuity and provides reliable, leak-free connections.

• Rigid, corrosion-resistant material ensures long-term durability.

• Color-coded for easy identification of Schedule 40 and Schedule 80 systems.

• Quick and easy installation, reducing labor and downtime.
