Old Castle C-904 4 Inch Corrugated Hdpe Wye Fitting

Product Description

The OLD CASTLE C-904 is a 4-inch corrugated HDPE wye fitting designed for use in drainage and stormwater management applications. Constructed from high-density polyethylene, this wye connects branch lines to main drainage runs at a 45-degree angle, allowing for smooth directional flow transitions. The snap-lock connection type enables fast, tool-free assembly in the field. Plumbers, drainage contractors, and site utility crews rely on this type of fitting when tying corrugated pipe runs together in residential and commercial drainage installations.

This fitting is suited for corrugated pipe drainage systems commonly installed in residential yard drainage, French drain configurations, roadside culvert laterals, and site grading projects. The 45-degree branch angle makes it appropriate for applications where a gradual flow transition from a lateral to the main line is required. The HDPE material resists corrosion, chemical exposure, and soil moisture, making it well-suited for direct burial installations.

Key Features

• 45-degree branch angle for smooth lateral-to-main-line flow transition
• Snap-lock connection for fast, tool-free field assembly
• High-density polyethylene construction resists corrosion and chemical exposure
• Sized for 4-inch corrugated pipe systems
• Suitable for direct burial in drainage and stormwater applications

Compatibility

Designed as an OEM-style replacement and standard fitting for 4-inch corrugated HDPE drainage pipe systems with snap-lock connections.

Installation Notes

Installation is typically performed by plumbers or site drainage contractors following applicable local plumbing and grading codes. Ensure the main line and branch pipe ends are clean and free of debris before engaging the snap-lock connection. Verify pipe alignment and proper slope before backfilling to avoid joint stress. Always follow local codes and manufacturer guidelines for burial depth and bedding requirements.
