The Innovation That Started It All

The LYCO® Anodeless Riser is Lyall’s flagship product with more than 15 million installed since its 1973 debut. As the first anodeless riser on the market to utilize a ground-level transition between PE pipe and the steel pipe of the riser outlet, the LYCO® Anodeless Riser eliminates the need for cathodic protection for below-ground, gas-carrying steel pipe.

  • Over 1,000 customer-specified product configurations

Key Features

  • Safe – The LYCO® transition fitting provides a PE to steel joint that is stronger than the PE pipe itself, while providing a 100% pressure-tested, leak-proof seal.
  • Cost-effective – Quality and volume are coupled with a simple, yet effective, design to deliver a product that begins with lower component costs and requires virtually zero field repair.
  • Reliable – Electrostatically applied epoxy coating on the riser casing provides long-term protection from corrosion, while the watertight, below-ground seal guards against moisture. Riser heads are coated with a protective urethane-based, corrosion-resistant primer.
