When specifying valves and fittings for fire-protection systems, the difference between UL Listing and FM Approval matters. Both are independent, third-party certifications, but they test to different standards and serve different assurance needs.
This guide explains what each mark covers, why many GCC projects require both, and how LEOCO products carry dual UL and FM approval across the fire-protection range.
Why it matters
For specifiers, contractors and distributors, choosing certified products protects both compliance and reputation. LEOCO manufactures to internationally recognised standards and supplies full certification with every order.
