Question: 1 / 400

What grade of hose is considered high-quality for acetylene fuel gas?

RM

The grade of hose that is considered high-quality for acetylene fuel gas is designated as RM. This classification indicates that the hose is specifically designed for handling acetylene and is constructed to withstand the pressures and conditions associated with acetylene usage safely. RM hoses are typically constructed with materials and reinforcement patterns that prevent the risk of leaks or bursts when used with flammable gases like acetylene.

Hoses that do not meet the RM grade may not have the same safety certifications or structural integrity required for the handling of acetylene, which can be a hazardous gas if not contained properly. It's important in welding and cutting applications to select the highest quality hoses available to ensure user safety and equipment reliability.
