3" Wye, Slip PVC SCH 40

Technical Specifications

The 3" Wye, Slip PVC SCH 40 (Part #475-030) is engineered for dependable performance across residential, commercial, and industrial plumbing systems. With a three-inch nominal size, this fitting features Socket × Socket × Socket slip connections for secure, solvent-weld installation. Made from durable Schedule 40 PVC, the fitting is lightweight, corrosion-resistant, and ideal for gravity flow or low-pressure liquid applications.

This white PVC wye meets ASTM D1784 material standards, rated for a maximum service temperature of 140°F. Contractors benefit from packaging options ranging from a carton quantity of five to a pallet quantity of 200, making it suitable for everything from small repairs to large project builds.

Typical Applications

A 3" PVC wye is trusted wherever a system needs a smooth, efficient branch connection that can maintain consistent flow. Its angled design minimizes turbulence and reduces clogging risk in systems where debris or high-volume water movement is common.

Several industries and systems rely on this fitting, such as:

• DWV plumbing systems (drainage, waste, and vent)
• Agricultural irrigation networks and water distribution lines
• Pool and spa plumbing for balanced flow direction
• Aquaculture and fish-farm systems requiring steady circulation
• Light commercial and industrial piping where angled routing improves system efficiency
• Stormwater management and runoff control systems

The flow-optimized wye branch makes this fitting especially beneficial in settings that prioritize preventing blockages and maintaining velocity.

Installation & Handling Tips

For the best results, follow the steps below to properly prepare the pipe and fitting before installation:

1. Clean all slip ends and sockets to remove dirt, moisture, or debris.
2. Apply PVC primer, followed by solvent cement, to each connection according to the manufacturer’s instructions.
3. Orient the wye correctly, confirming that the branch angle supports natural flow direction in drainage or irrigation systems.
4. Insert the pipe fully and hold briefly to prevent push-out during initial set.
5. Support the piping system, especially around the branch, to avoid stress that can weaken joints.
6. Allow proper curing time before pressure testing or operation.
7. Avoid over-tightening straps or clamps that may place unnecessary pressure on the fitting.
