4 inch PVC SDR35 Wye Gasket x Gasket x Gasket

4-Inch PVC SDR35 Wye – Gasket x Gasket x Gasket for Gravity Sewer Applications

The 4-inch PVC SDR35 Wye is a gravity-flow sewer fitting engineered to join three PVC SDR35 pipe sections at a consistent angle, allowing smooth redirection of flow in non-pressurized underground systems. The triple gasketed bell ends provide reliable sealing without solvent cement, making it suitable for quick, code-compliant installations in municipal and private sanitary sewer networks.

Designed to meet ASTM D3034 specifications, this wye fitting ensures dimensional accuracy and consistent wall thickness, contributing to long-term performance in standard gravity sewer systems.

Key Performance Features

• ✅ SDR35 Rating – Manufactured for use with sewer pipe systems requiring a Standard Dimension Ratio of 35, ensuring compatibility and uniform pressure handling across the system.
• ✅ Flexible Gasket Connections – Factory-installed elastomeric gaskets reduce installation time while providing a secure, watertight seal without the need for solvent welds.
• ✅ Impact-Resistant PVC Construction – Resists deformation during handling and burial, maintaining shape under soil load conditions.
• ✅ Low-Angle Branch Entry – Designed for gradual flow transition, minimizing turbulence and blockage potential at the intersection point.
• ✅ Code-Conforming Design – Suitable for use in systems governed by IPC, UPC, and local sewer codes.

Installation Parameters

This fitting is intended for use in gasketed underground sewer piping systems. To ensure optimal joint integrity, clean all gasket surfaces and lubricate with an approved pipe joint lubricant before assembly. Use line laser or transit to maintain proper slope and alignment. Avoid over-insertion to prevent gasket displacement.

Typical Applications

Primarily used in underground sanitary sewer systems, the 4-inch SDR35 wye is suitable for residential subdivisions, commercial drainage layouts, and civil infrastructure. It is frequently installed in mainline-to-branch connections, cleanout configurations, and distribution laterals.

Material Notes

PVC SDR35 pipe and fittings are widely adopted for wastewater conveyance due to their corrosion resistance, lightweight handling, and ease of field adjustment. Gasketed joints also allow for limited expansion, contraction, and minor ground movement without compromising seal integrity.
