Westlake Pipe Fittings g1164 Pvc Sewer Plug 4 Inch Sdr 35

Product Description

The WESTLAKE PIPE FITTINGS g1164 is a 4-inch SDR 35 PVC sewer spigot pipe plug designed to cap or temporarily seal spigot-end sewer pipe during installation, testing, or system modification. Made from PVC, this plug fits directly into the bell end of compatible SDR 35 sewer pipe, creating a secure, watertight stop. At 0.35 pounds, it is lightweight and easy to handle on the job. Plumbers and sewer contractors rely on this type of fitting when pressure-testing drain lines, capping unused laterals, or staging pipe runs before final connection.

This plug is suited for residential and light commercial gravity sewer and drain applications where SDR 35 PVC pipe is the standard. It is commonly installed during new construction, sewer lateral replacement, or trench work where individual pipe sections must be isolated or tested before the system is fully commissioned. The spigot connection style allows it to insert directly into the bell of the mating pipe without additional adapters.

Key Features

• PVC construction resists corrosion and chemical degradation common in sewer service environments
• SDR 35 schedule rating matches standard gravity sewer pipe used in residential and commercial drain systems
• 4-inch spigot connection inserts directly into bell-end SDR 35 pipe
• Lightweight at 0.35 pounds for easy single-hand placement in the trench
• Suitable for use during pressure and leak testing of sewer laterals

Compatibility

Designed as an OEM-style replacement fitting for use with 4-inch SDR 35 PVC sewer pipe systems utilizing spigot-and-bell connections.

Installation Notes

Installation is typically performed by licensed plumbers or sewer contractors in accordance with local plumbing codes and IPC guidelines. Ensure the bell end of the receiving pipe is clean and free of debris before inserting the spigot plug. If the plug is being used for a pressure or leakage test, follow the test pressure limits specified by the applicable local code for gravity sewer systems. Do not exceed the pressure rating of the pipe or fittings in the connected system.
