3 in. Schedule 80 PVC Coupling SCH-80 Pipe Fitting NSF ASTM D2467 3" Slip/Socket

The 247Garden 3 in. Schedule 80 PVC Coupling is engineered for strength, durability, and high-pressure performance in demanding piping systems. Manufactured to meet ASTM D2467 standards and NSF-certified for potable water applications, this heavy-duty coupling is designed for long-lasting reliability in both residential and industrial projects.

Featuring slip/socket ends on both sides, this coupling allows for easy solvent welding and a leak-free seal when connecting two 3-inch Schedule 80 PVC pipes. The thicker wall construction of Schedule 80 PVC offers superior impact resistance, higher pressure handling, and enhanced chemical resistance compared to Schedule 40 fittings.

Ideal for applications where strength and reliability are essential, including:

• Water distribution and treatment systems

• Irrigation and agricultural pipelines

• Aquaculture and hydroponics setups

• Industrial fluid and chemical handling

• HVAC and utility piping

Key Features:

• Size: 3 in. Schedule 80 PVC Coupling (Slip/Socket)

• Meets ASTM D2467 specifications and NSF-certified

• Superior wall thickness for higher pressure systems

• Slip/socket ends for strong solvent-welded joints

• Resistant to rust, scaling, and chemical corrosion

• Perfect for industrial, commercial, and heavy-duty residential use

PVC Cement Recommendation:
For best results, use a heavy-bodied PVC cement formulated for Schedule 80 fittings, such as Oatey Heavy Duty Gray PVC Cement (or equivalent). Always pair with a PVC primer for maximum bond strength.

Other Schedule 80 Fittings from 247Garden (3 in. or Compatible Sizes):

• 3 in. SCH80 90° and 45° Elbows – Smooth directional changes under pressure.

• 3 in. SCH80 Tees – Create strong branch connections.

• 3 in. SCH80 Adapters (Socket x Thread / Spigot x Thread) – Transition between threaded and solvent-welded systems.

• 3 in. SCH80 Unions – Allow for easy pipe disconnection and maintenance.

• 3 in. SCH80 Ball Valves – Heavy-duty flow control for high-pressure systems.

Alternative Option – Schedule 40 for Standard Use:
If your project does not require the heavy-duty pressure rating of Schedule 80, consider 247Garden 3 in. Schedule 40 PVC Couplings and Fittings. They are lighter, more cost-effective, and ideal for irrigation, drainage, and low-pressure water systems.
