6 inch PVC SDR 35 Coupling without Stop Gasket x Gasket

G626 SDR35 6" GXG Coupling Without Stop – Built for Subsurface Drainage Integrity

The G626 SDR35 gasket x gasket (GXG) coupling without stop is designed for joining 6-inch SDR35 PVC sewer and drainage piping. Manufactured to meet ASTM standards for gravity flow applications, this fitting provides a secure seal suitable for buried installations where groundwater resistance and joint flexibility are essential.

Its stop-free configuration allows full insertion and axial adjustment of pipe ends during layout or repair. The dual-gasket design supports leak-resistant performance in gravity wastewater systems, with consistent joint compression when used with SDR35-compatible bell ends or spigots.

Functional Performance Advantages

• ✅ Gasket x Gasket Sealing Dual elastomeric seals provide watertight joints with minimal installation effort.
• ✅ Stop-Free Interior Allows unobstructed insertion depth and facilitates adjustments in field conditions.
• ✅ Engineered for SDR35 Systems Designed for compatibility with SDR35-rated PVC pipe per ASTM D3034.
• ✅ Durable for Buried Service Withstands typical soil loads and minor deflection without joint failure.

Technical Specifications

• Nominal Size: 6 inches
• Fitting Type: SDR35 coupling (no center stop)
• Connection: Gasket x Gasket (GXG)
• Standards: Complies with ASTM D3212 and D3034 for gravity sewer applications

Installation Guidance

Ensure pipe ends are clean, chamfered, and lubricated with approved gasket lubricant before insertion. The absence of an internal stop allows for full engagement, which is especially useful in repair scenarios or when custom spacing is required between structures. No solvent welding is used; sealing is achieved via mechanical compression of the gasket interface.

Typical Applications

This fitting is specified for use in underground non-pressurized sewer and stormwater conveyance systems. Common installations include laterals, manhole connections, and trench-laid horizontal runs in both residential and light commercial environments.

Industry Note

SDR35 PVC systems provide an optimal balance of wall thickness and hydraulic capacity, and are widely accepted in municipal and private underground drainage infrastructure. Proper joint preparation and fitting selection are key to long-term service performance.

Fittings like the G626 GXG coupling without stop streamline pipe joining while maintaining compliance with gravity drainage standards. Use where flexibility in joint depth and reliable sealing are critical to installation success.
