Flange connections are essential for many plumbing and piping projects, especially when flexibility and ease of disassembly are crucial. Like other PVC fittings, vinyl flanges from 247Garden are lightweight, corrosion-resistant, and easy to install. However, they require special care during installation to ensure long-lasting performance due to the physical properties of PVC and CPVC, which differ from metals. This guide will explain when and how to use PVC flanges, and recommend the best sizes from 247Garden's PVC TS and Van Stone Flange collections.

Why Use PVC Flange Connections?

Flanges provide a secure, reliable connection and are often used in the following scenarios:

  • Frequent Dismantling: Flange connections make it easy to take apart sections of a piping system for maintenance or replacement.
  • Temporary Installations: Ideal for projects where the setup may need to be moved or reconfigured frequently.
  • Transitioning Between Materials: When connecting different materials (e.g., PVC to metal), a flange connection can prevent complications from cementing incompatible surfaces.
  • Non-Cement-Friendly Environments: In areas where solvent cement isn’t suitable (e.g., in cold or wet conditions), flanges provide a solid alternative.

Types of Flanges from 247Garden

At 247Garden, we offer two primary types of PVC flanges:

  • Socket-Type Flanges (TS): Designed for permanent pipe installations where the pipe is inserted into the fitting and solvent-welded.
  • Van Stone Flanges: Feature a two-piece design where the bolt ring can spin freely, making it easier to align bolt holes during assembly.

Most vinyl flanges at 247Garden are rated to handle a maximum working pressure of 150 psi at 73°F (22.7°C), ensuring durability and reliability in a wide range of applications.

Installation Tips for PVC Flanges

  • Support the System: Ensure that your PVC flange does not bear the weight of large components like cast iron valves. Use additional supports to prevent stress on the flange connection.
  • Bolt Alignment: When using Van Stone flanges, take advantage of the rotating bolt ring to easily align the bolt holes without putting strain on the pipe or flange.
  • Correct Torque: Over-tightening bolts can damage the flange or create leaks. Tighten bolts in a crisscross pattern to distribute pressure evenly.
