The CKVIHAV 4-piece set features 1-1/2 inch Schedule 40 PVC pipe with a 1.90 inch outer diameter and 1.58 inch inner diameter. Designed for indoor or outdoor use, these pipes offer corrosion resistance and long service life. They are suitable for greenhouse frames, DIY shelving, and lightweight structural projects. Installation is straightforward with primer and solvent cement to create secure, durable joints. The pipes are optimized for smooth, clean cuts and efficient fluid movement, reducing the likelihood of clogs in irrigation lines or conduit runs.
CKVIHAV 6Pcs 1/2 Inch PVC Pipe 17″ Long
These 6 pieces measure 17 inches each, offering a compact and versatile option for greenhouse frame connectors, uprights, or lightweight supports. The 1/2 inch Schedule 40 PVC pipes provide durability and good plasticity, with UV resistance and low-temperature tolerance, enabling reliable performance across seasons. Like other Sch40 pipes, installation uses standard primer and cement for solid, long-lasting joints, and the smooth surface supports precise cutting and minimal material waste.

LetFix offers furniture-grade 1 inch PVC pipe in a 20-pack, ideal for greenhouse projects like frame shoulders, crossbars, and shelving supports. The pipes are UV-resistant to tolerate sun exposure and maintain color and integrity over time. Their pure white, logo-free exterior delivers a clean, professional appearance for visible structures, while the durable SCH 40 material ensures reliable performance in outdoor environments and humid greenhouse conditions.
letsFix 1/2″ PVC Pipe 4 Pack
This 4-pack of 1/2 inch, furniture-grade PVC pipe is built for DIY greenhouse tasks such as framing small enclosures, trellises, or net supports. UV inhibitors protect the pipe from sun damage, helping it resist cracking, color fading, and degradation. The white, logo-free surface provides a professional finish, suitable for greenhouse interiors and visible exterior frames.
3/4 Inch PVC Pipe, 4-Pack
The 3/4 inch PVC pipe set is another versatile option for greenhouse construction, including uprights, light-duty frames, and conduit paths. The Schedule 40 designation ensures a sturdy wall thickness for structural integrity while remaining lightweight for easy handling. UV resistance and a smooth surface simplify cutting, joining, and finishing touches for durable, long-lasting greenhouse projects.
Buying Guide: Key Purchase Considerations
- Pipe size and compatibility: Match pipe diameter to the required frame or irrigation connections. Larger pipes offer greater strength for framing, while smaller diameters work well for nets, trellises, and conduit routes.
- Material type and schedule: Schedule 40 PVC is common for DIY greenhouse builds due to its balance of strength, flexibility, and availability. Confirm UV resistance for outdoor exposure and temperature tolerance for your climate.
- UV exposure and color: UV inhibitors help prevent cracking, yellowing, and degradation. Pure white finishes look cleaner for visible greenhouse interiors and can help reflect light.
- Installation method: Most PVC systems require primer and solvent cement for secure joints. Ensure you have these supplies and proper ventilation during bonding.
- Durability vs. ease of use: Heavier gauge pipes (larger diameters) provide stronger frames but are less flexible. For complex greenhouse shapes, a mix of diameters can optimize both strength and ease of assembly.
- Pack quantity and project scale: Choose multi-pack options that align with your planned structure size to minimize waste and reduce trips to the store or online order.
- Accessories: Consider clamps, tee fittings, elbows, and supports that match your pipe sizes to complete the greenhouse frame and cover system efficiently.
- Durability and longevity: The selected Sch40 pipes deliver robust performance for several seasons with proper care.
- Ease of cutting and joining: Smooth surfaces and standard cement compatibility help ensure clean joints and reliable connections.
- Versatility: Sizes from 1/2″ to 1-1/2″ cover a wide range of greenhouse tasks, from frames to irrigation conduits and shelves.
