Why UL-Listed Brass Valves Are a Must for Gas Applications

Why UL-Listed Brass Valves Matter for Gas Systems

When it comes to natural gas or propane systems, safety is non-negotiable. The valve you choose can mean the difference between a secure installation and a major hazard. That’s why UL-listed brass valves are the gold standard for gas applications in residential, commercial, and industrial environments.

At Enolgas USA, our UL 842 listed gas valves deliver the safety, compliance, and durability

your gas systems demand.

Comparison of UL-Listed and Non-Listed Valves: UL-Listed valves ensure code compliance, leak-tight performance, and rigorous testing, while non-listed valves pose risks of leaks and inspection failures.

What Does UL Listing Mean?

UL (Underwriters Laboratories) is a globally recognized safety certification organization. A

UL-listed valve has passed rigorous testing for leak-tightness, material integrity, and fire

safety, ensuring it performs reliably under gas line conditions.

For gas valves, UL 842 is the relevant standard. It certifies that a valve:

• Is leak-proof under pressure

• Can withstand temperature fluctuations

• Meets fire safety requirements

• Is suitable for natural gas and LP (liquefied petroleum) gas

Understanding UL 842 Certification: Ensures leak-proof performance under pressure, meets fire safety standards, supports both natural and LP gas use, and guarantees third-party verification.

Top Reasons to Use UL-Listed Brass Valves in Gas Applications

1. Code Compliance

Most building codes, including those enforced by the International Fuel Gas Code (IFGC) and NFPA (National Fire Protection Association), require gas valves to be UL-listed or CSA

certified.

Using a non-listed valve could lead to:

• Inspection failures

• Delayed permits

• Liability in case of gas leaks or fires

2. Proven Safety Standards

UL-listed valves undergo pressure tests, thermal cycling, and fire resistance testing. They’re

verified to:

• Prevent gas leaks

• Resist corrosion and temperature shock

• Maintain seal integrity under fluctuating gas loads

3. Product Traceability and Trust

A UL mark assures buyers and inspectors that your valve:

• Comes from a verified manufacturing source

• Has passed third-party safety certification

• Is backed by routine audits and factory inspections
