Available
Bossweld gas hose fittings and connectors provide safe, leak-free connections on oxygen, acetylene, and LPG gas lines.

Where this product is used
Gas hose fittings and connectors are standardised by gas type — right-hand thread for oxygen, left-hand for fuels.
- Oxy-fuel gas line connections and extensions in workshops
- Replacement fittings on oxygen, acetylene, and LPG hose assemblies
- Gas equipment maintenance and system assembly
Selecting the right option
Fittings must suit the gas — right-hand thread for oxygen, left-hand (often with knurled nut) for fuel gases. Size is matched to hose internal diameter (5mm, 6mm, 8mm). Crimp connectors are more reliable than barb fittings for permanent assemblies.
