4 inch PVC SDR 35 Plug

4 inch WEST G1164 SDR 35 PVC Plug – Solvent Weld End Seal for Gravity Sewer Systems

The WEST G1164 SDR 35 4 inch plug is a solvent weld fitting designed to cap off open ends in SDR 35 sewer and storm drainage piping systems. Manufactured from Type I, Grade I PVC, this component is engineered for non-pressurized, gravity-flow systems in compliance with ASTM D3034 and F1336 specifications.

Its slip-fit hub design allows for straightforward installation using standard solvent cement procedures. Commonly used in underground installations, the plug serves as a permanent or temporary closure for cleanouts, service connections, or future expansion points in municipal and private infrastructure.

Technical Specifications

• Product Code: G1164
• Nominal Size: 4 inch
• Material: Polyvinyl Chloride (PVC) Type I, per ASTM D1784 Cell Class 12454
• Wall Rating: SDR 35 (Standard Dimension Ratio – gravity-rated)
• Connection Type: Spigot (Slip-fit for solvent weld installation)
• Compliance: Meets ASTM D3034 and F1336 standards

Key Features

• ✅ SDR 35 Compatibility: Designed for use with SDR 35 PVC sewer and drainage piping systems
• ✅ Corrosion-Resistant Material: PVC body resists chemical degradation, microbial growth, and long-term soil exposure
• ✅ Low-Profile Closure: Smooth spigot end allows for direct solvent welding without added adapters or reducers
• ✅ Field-Ready Durability: Rated for underground installation in sanitary sewer and stormwater applications

Installation Guidance

To install, clean mating surfaces and apply ASTM D2564 solvent cement. Insert the spigot fully into a compatible SDR 35 hub fitting and allow for proper cure time as recommended by the cement manufacturer. This plug is designed for permanent termination; do not use in pressurized or hot water systems.

Applications

The G1164 SDR 35 plug is commonly used in:

• Sanitary sewer laterals and cleanouts
• Stormwater drain lines
• Unused branch lines requiring closure
• System isolation during construction staging

Engineering Note

SDR 35 PVC components are rated for non-pressurized use in gravity-flow systems only. Installation must follow all local plumbing or civil engineering codes, including bedding, cover, and load specifications for buried piping systems.

The 4 inch WEST G1164 SDR 35 plug provides a secure solvent-welded seal for terminating PVC sewer piping runs. Its structural integrity and corrosion resistance make it a dependable choice for long-term closure in underground drainage networks.
