2 inch PVC Schedule 40 Union with O-Ring Plastic x Plastic

2" PVC Schedule 40 Union with O-Ring Seal – Socket x Socket

The 2" PVC S40 Union with O-Ring is engineered for systems requiring periodic disassembly without compromising line integrity. This union is molded from rigid Schedule 40 PVC and incorporates a reliable elastomeric O-ring for a positive seal between pipe segments. Designed for socket (slip) connections on both ends, this union is a practical solution for pressurized and non-pressurized piping systems where maintenance access is required.

Key Features

• ✅ Schedule 40 Construction – Suitable for moderate pressure systems, compatible with potable water, irrigation, and certain chemical applications
• ✅ EPDM O-Ring – Provides a resilient, re-sealable leak barrier under varying thermal and pressure conditions
• ✅ Removable Union Design – Allows for easy disconnection and service without cutting pipe
• ✅ Corrosion Resistance – PVC material resists degradation from most acids, bases, salts, and organic compounds
• ✅ Precision Fit – Molded to tight tolerances for consistent performance in field installations

Technical Specifications

• Material: PVC (ASTM D1784, cell classification 12454)
• Nominal Size: 2 inch
• Connection Ends: Socket x Socket (solvent weld)
• Pressure Rating: 150 PSI @ 73°F (non-shock)
• Seal Material: EPDM O-ring
• Standards: Complies with ASTM D2466 and NSF 14/61 for potable water systems

Installation Notes

Ensure pipe ends are properly deburred, clean, and square-cut before solvent welding. Avoid overtightening the union nut to protect the O-ring seal. For maximum performance, apply primer and solvent cement in accordance with ASTM guidelines. Use in accordance with applicable local codes and pressure/temperature charts specific to PVC.

Typical Applications

Commonly installed in residential, commercial, and light industrial systems including water distribution, pump assemblies, pool and spa systems, aquaculture, and chemical process lines. Especially useful where component replacement or future maintenance access is required.

Code & Compliance Note

PVC Schedule 40 unions are certified for potable water use and meet pressure and dimensional requirements per ASTM standards. They are not intended for compressed air or gas systems.

For contractors requiring a reliable, re-sealable connection in PVC pressure or drain systems, the 2" Schedule 40 union with EPDM O-ring provides a dependable and serviceable solution engineered for long-term performance.
