6 inch PVC SDR 35 Plug

6 inch SDR35 PVC Plug – Termination Fitting for Gravity Sewer Systems

The 6 inch SDR35 Plug is a solvent-weld fitting designed to seal the end of SDR35 PVC piping used in non-pressurized gravity drainage systems. Commonly installed at the termination of sewer laterals, cleanouts, or unused branch connections, this plug ensures a watertight seal that complies with municipal plumbing standards.

Fabricated from PVC material that meets ASTM D3034 requirements, the plug offers chemical resistance and long-term durability in subsurface and wet-soil installations. Its plain-end configuration allows for direct bonding using solvent cement, providing a permanent closure in both residential and commercial underground drainage networks.

Key Performance Features

• ✅ Material Compliance: Constructed from PVC conforming to ASTM D3034 for SDR35-rated sewer applications.
• ✅ Nominal Fit: Engineered for solvent-weld installation into 6 inch SDR35 bell fittings or couplings.
• ✅ Sealing Integrity: Forms a secure, leak-resistant seal for unused lines, cleanouts, or test points.
• ✅ Corrosion-Resistant: Non-metallic composition resists degradation in acidic or alkaline soil conditions.
• ✅ Service Longevity: Suitable for long-term burial under standard gravity flow conditions.

Technical Specifications

• Nominal Size: 6 inch
• Fitting Type: Solid end plug
• Connection Style: Plain-end for solvent weld
• Standard Dimension Ratio: SDR 35
• Material: PVC (Polyvinyl Chloride)
• Compliance: ASTM D3034, meets requirements for gravity sewer systems

Application Scope

Used extensively in gravity sewer and stormwater systems, the 6 inch SDR35 Plug is suited for capping lines during system testing, sealing future extensions, or terminating unused service laterals. It is compatible with other SDR35 solvent-weld components and intended for underground installations with limited access after backfill.

Installation Notes

This fitting must be installed using solvent cement approved for PVC sewer applications. Ensure proper surface preparation and curing time to maintain seal integrity. When used in a cleanout assembly or test configuration, it may be installed in conjunction with an adapter or threaded access point as required by local code.

Technical Insight

SDR35 fittings are specified for low-pressure gravity flow and are not suitable for pressurized systems. Their wall thickness and dimensional standardization support consistent performance across a broad range of utility infrastructure projects.

The 6 inch SDR35 PVC Plug offers a simple yet essential solution for closing off branches in sanitary sewer systems. Built to code, resistant to corrosion, and engineered for direct solvent bonding, it supports system longevity and regulatory compliance in underground drainage infrastructure.
