Which of the following is true concerning the hose threads on compressed gas oxy-acetylene regulators and torches?

🔍 Key Concepts

• Standard safety convention for gas hose thread directions: fuel gas vs. oxygen • How to quickly identify left-handed vs. right-handed threads on fittings • Why regulators and torch inlets must prevent accidental cross-connection between oxygen and fuel gas

💭 Think About

• Think about which gas (oxygen or acetylene) is considered the fuel and which is the oxidizer, and how safety standards usually distinguish their fittings. • Ask yourself: if you wanted to prevent someone from accidentally connecting an oxygen hose to a fuel gas port, what simple mechanical difference in the threads would you use? • Consider whether the same convention (left- or right-handed) is kept the same for a gas from regulator outlet to torch inlet, or if it would ever be reversed along the line.

✅ Before You Answer

• Identify which gas (oxygen vs. acetylene) typically uses right‑handed standard threads in industry practice. • Identify which gas typically uses left‑handed (often notched) threads for safety, to avoid cross‑connection. • Check that your chosen option keeps the thread direction consistent from the regulator outlet to the torch inlet for that same gas.
