TekTube Schedule 40 Ultra Flex PVC Pipe – 2″ x 10 ft
This 2″ Ultra Flex PVC pipe shares the same premium construction as the 1.5″ variant, optimized for pool and spa plumbing where larger diameter runs are needed. It remains NSF certified and IAPMO approved, with a non-toxic FDA formulation and UV resistance. Appropriate PVC glue and curing time are required for secure connections to fittings.
TekTube Schedule 40 Ultra Flex PVC Pipe – 1″ x 10 ft
This 1″ option is designed for tight spaces and routes with minimal space. TekTube’s Ultra Flex formulation reduces stiffness, enabling easier bends around obstacles. As with other Ultra Flex products, it is NSF certified, IAPMO approved, and made with FDA non-toxic materials. Suitable for burying or running above ground with proper glue and cure times.
Ultra Flex White Schedule 40 PVC Pipe – 1-1/2″ x 10 ft
This Ultra Flex line focuses on ease of handling in tight spaces while maintaining true Schedule 40 standards. It is noted for its crush and impact resistance and is recommended for pools and spas. It uses standard Schedule 40 fittings and PVC glue, and it can connect to rigid PVC with ease. It is not recommended for dead-head, static pressure situations.
Sealproof 2″ Dia Flexible PVC Pipe
Sealproof PVC pipe is designed for both above and below ground installations and is compatible with PVC Schedule 40 fittings. It requires compatible primers and cements and is FDA non-toxic per IAPMO TSC 31-90. The pipe is manufactured in the United States from high-quality virgin PVC, featuring a smooth surface and a relatively low fittings requirement due to its flexible wall design.
TekTube 1/2″ Dia Ultra Flexible PVC Pipe
This 1/2″ diameter TekTube option offers enhanced flexibility for intricate layouts. Made in the USA, it is touted as NSF-certified Ultra Flex PVC and is available in multiple sizes, including 1/2″, 3/4″, 1″, 1-1/4″, 1-1/2″, 2″, 3″ and 4″. It is not designed for dead-head scenarios with static pressure but provides easy routing for water features and spa plumbing.
Buying Guide: Key Purchase Considerations
- Diameter and length: Match pipe size to fittings and desired flow. Larger diameters reduce friction but require more space.
- Flexibility vs. rigidity: Ultra Flex PVC is designed for ease of routing in tight spaces; standard Schedule 40 PVC is more rigid but durable.
- Certification and safety: Look for NSF certification and IAPMO approval when installing in pools, spas, or water features.
- UV resistance and exposure: Outdoor installations benefit from UV-resistant formulations to minimize degradation.
- Installation requirements: Use the correct solvent cement, follow cure times, and ensure compatibility with fittings and clamps.
- Application scope: Consider buried vs. above-ground use, water pressure tolerance, and compatibility with aquaculture or decorative features.
- Manufacturer and regional standards: US-made pipes support quality control and compliance.
In summary, selecting the right schedule 40 flexible PVC pipe involves balancing diameter, flexibility, and certification with the specific layout of your pool, spa, or water feature. The options above cover a range of sizes and formulations to fit common installation scenarios while adhering to safety and performance standards.
