Goss HA3-12 Acetylene Hose 12 Feet A-fittings

Product Description

The GOSS HA3-12 is a 12-foot acetylene hose fitted with A-style fittings, designed for use in gas welding and cutting applications. It connects an acetylene supply cylinder or manifold to a torch body, carrying fuel gas at working pressures typical of oxy-acetylene setups. The A-fitting designation indicates a standard left-hand thread connection used specifically for fuel gases, reducing the risk of accidental cross-connection with oxygen lines. Licensed welding technicians, plumbers, and HVAC service techs who perform brazing or soldering work are the primary installers of this hose.

This hose is suited for professional trade environments where acetylene is used as a fuel gas for cutting, brazing, or welding. It is appropriate for both shop bench work and field service calls where a portable oxy-acetylene rig is required. The 12-foot length provides adequate reach for most standard torch setups without excess hose slack that could become a jobsite hazard.

Key Features

• 12-foot length provides practical reach for torch work in shop and field settings
• A-style fittings feature left-hand threads, the industry-standard configuration for acetylene and other fuel gases
• Designed specifically for acetylene service in oxy-fuel cutting and brazing rigs
• Sold as individual hose unit

Compatibility

Designed as an OEM-style replacement or service hose for oxy-acetylene torch setups using standard A-style left-hand thread fuel gas connections.

Installation Notes

Installation should be performed by a qualified welding technician or trade professional familiar with compressed gas equipment. Always close cylinder valves and bleed all pressure from the hose before disconnecting or connecting fittings. Inspect the hose for cuts, kinks, or abrasion before each use and replace if any damage is found. Do not use thread sealants or PTFE tape on A-fitting connections — these fittings rely on metal-to-metal seating.
