Product Number: 35018
The Draper 35018 is a flashback arrestor for oxy-acetylene welding and cutting equipment, preventing the dangerous backflow of flame into the gas supply hose and regulator. Flashback arrestors are essential safety devices — fit them on both oxygen and acetylene hoses close to the torch. Replace if they have operated (arrested a flashback) — internal components may have been damaged by the event. Never use oxy-acetylene equipment without working flashback arrestors. Stocked for fast UK delivery. Also found under oxy-acetylene safety, welding safety, gas welding equipment in the PartsForMachines.com welding range.
Additional Information:
Large sintered element coupled with non return valve. 3/8" BSP connectors.

A. The Draper 35018 is specifically for the gas hose in an oxy-acetylene setup. You need separate flashback arrestors for each gas — one on the oxygen hose and one on the acetylene hose, positioned close to the torch.
A. Replace the Draper 35018 immediately if it has operated (arrested a flashback). Internal valves and filter elements may be damaged by the high-temperature event. Also replace if the body is visually damaged, corroded, or if gas flow is restricted. Never attempt to repair a flashback arrestor — replace it.
A. Fit flashback arrestors on both the oxygen and acetylene hoses, close to the torch. Some setups also use arrestors at the regulator end. The closer to the torch, the shorter the length of hose that can be ignited in a flashback. Always use them in pairs — oxygen side and fuel gas side.
A. A flashback occurs when the flame burns back into the hose and regulator rather than at the torch tip. Causes include blocked nozzle, hoses touching the workpiece, overheated torch, or incorrect gas pressures. Without a flashback arrestor, the flame can reach the cylinder valve, causing catastrophic failure. Flashback arrestors automatically shut off gas flow when backfire conditions are detected.
A. A correctly functioning flashback arrestor introduces minimal flow restriction. If you notice significantly reduced gas flow through the Draper 35018, the internal check valve may have partially activated. Test with soapy water for leaks and replace if flow restriction is present.
A. Flashback arrestors for oxy-fuel equipment should comply with EN 730 (UK/EU) or equivalent standard. This covers backfire and flashback protection, gas flow direction, and burst pressure requirements. Always verify the EN 730 markings on any flashback arrestor before use.
A. Flashback arrestors are typically hose-connection size specific (typically 3/8" BSP). Provided the thread size and gas type match, the Draper 35018 can be used on different torch assemblies. Always confirm the correct gas-specific type (oxygen vs acetylene) — they are not interchangeable.
A. Check that gas flows freely through the arrestor when connected and valves are open. Close the gas supply and check that the arrestor holds the pressure (no hiss from the torch end). An arrestor that allows back-flow when pressure is applied from the torch end indicates a failed check valve — replace immediately.
A. At minimum you need a welding helmet or headshield (auto-darkening recommended), leather welding gauntlets, a fire-resistant apron or jacket, and steel-toe boots. For enclosed spaces, a fume extractor or respirator is essential. A welding curtain or screen protects bystanders from UV flash. Keep a fire extinguisher accessible.
A. Yes — the Draper 35018 is UK stocked for fast despatch. Check current availability at PartsForMachines.com.
