Akulon® Fuel Lock

Leading global manufacturers have trusted Akulon Fuel Lock nylon/polyamide (PA6) monolayer technology for years, and the third-generation technology continues to deliver superior performance versus HDPE.

Explore Akulon® Fuel Lock

Born out of the need for a more eco-friendly product after stricter emissions regulations, Akulon Fuel Lock emerged as a functional replacement for the HDPE materials commonly used for small-engine fuel tanks.

Envalior continues to offer many cutting-edge products that meet the needs of the ever-changing global community. Akulon Fuel Lock is just one of those products, emerging as the perfect material for use in small-engine fuel tanks.

In the 1990s, stricter guidelines for reducing the evaporative emissions of small off-road equipment were instituted by the California Air Resources Board (CARB) and the Environmental Protection Agency (EPA). With other countries preparing to follow suit, Envalior saw an opportunity to make an environmental impact in the outdoor power equipment (OPE) industry, leading to the 2011 launch of our Fuel Lock products.

Today, leading global manufacturers have trusted Akulon for years, and the third-generation technology continues to deliver superior performance versus HDPE.
