  • Regulator, valve, manifold, pump, and gauge repair

Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Control and Valve Installers and Repairers, Except Mechanical Door

Repairing regulators and valves on oxygen and nitrogen servicing equipment transfers directly to mechanical valve and control-device repair.

How to prepare: Compare the valve types in target openings with your repair experience, then seek hands-on instruction for unfamiliar devices.

What the civilian work involves
  • Disassemble and repair mechanical control devices or valves, such as regulators, thermostats, or hydrants, using power tools, hand tools, and cutting torches.
  • Record maintenance information, including test results, material usage, and repairs made.

Industrial Machinery Mechanics

On-equipment repair and intermediate maintenance of servicing trailers, pumps, and manifolds provide relevant experience for industrial equipment maintenance.

How to prepare: Target openings involving pumps and fluid-handling equipment, and prepare a repair-work portfolio showing the components you maintained and the repairs you performed.

What the civilian work involves
  • Repair or maintain the operating condition of industrial production or processing machinery or equipment.
  • Repair or replace broken or malfunctioning components of machinery or equipment.
  • Disassemble machinery or equipment to remove parts and make repairs.
