Outer diameter is about 1.90″ and inner diameter around 1.58″, making them suitable for basic DIY tasks, greenhouse frames, and light furniture projects.

The pipe is designed for water piping and general DIY uses, with smooth inner walls aiding flow and ease of processing. Best for outdoor or sun-exposed projects due to high impact resistance.

Buying Guide: Key Considerations for 1.5″ PVC Pipe
- Pipe grade: Choose SCH40 for structural strength and plumbing tasks; furniture-grade pipes offer a cleaner look and UV resistance for outdoor use.
- Diameter accuracy: OD typically around 1.90″ for 1-1/2″ pipes; ensure your fittings match internal and external diameters for tight seals.
- Length needs: Plan runs and joints; fixed lengths (like 17″ or 40″) may require more fittings for longer constructions.
- Application environment: Outdoor, sun exposure, or hot/cold water use can influence material choice and UV inhibitors.
- Installation method: Many pipes require primer and solvent cement; confirm compatibility with fittings in your kit.
