When installing PVC flanges, achieving a secure and leak-free connection is essential. One of the most reliable ways to ensure this is by using an EPDM flange gasket. At 247Garden, we provide high-quality EPDM gaskets designed to pair perfectly with Schedule 40 and Schedule 80 PVC flanges.

What Is an EPDM Gasket?

EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber known for its excellent resistance to water, steam, ozone, and many chemicals. Unlike rigid plastic or metal-to-metal connections, EPDM provides flexibility and durability in sealing applications.

This makes it an excellent choice for irrigation, plumbing, hydroponics, and industrial water systems where reliability and long service life are critical.

How an EPDM Gasket Works with PVC Flanges

PVC flanges are strong and rigid, but even with precision machining, tiny gaps and surface irregularities exist. Without a gasket, those gaps can allow leaks under pressure.

Here’s where the EPDM gasket comes in:

  1. Creates a Compression Seal – When placed between two PVC flanges and tightened with bolts, the gasket compresses to fill any uneven surfaces.
  2. Prevents Leakage – The flexible rubber forms a continuous barrier that resists water, air, and chemical seepage.
  3. Handles Movement – EPDM maintains its sealing ability even when pipes expand, contract, or vibrate.
  4. Chemical and Weather Resistance – EPDM stands up to acids, alkalis, and outdoor exposure, ensuring a long-lasting seal.

Why EPDM Is the Preferred Gasket Material

  • Durability – Withstands years of use without cracking or losing elasticity.
  • Versatility – Suitable for fresh water, irrigation, and light chemical applications.
  • Reliability – Provides consistent performance across a wide temperature range.
