Frequently Asked Questions
What is this used for?
The Dominator 48/4500 Carbon Fiber HPA Tank DS-U00500 is an HPA (high-pressure air) component for airsoft HPA setups. Match its pressure rating and fittings to the rest of your rig — regulator, line, and tank must all be rated for the same working pressure.
What does the size rating mean?
The 48/4500 figure is the tank’s volume / pressure rating as listed in the title. Larger volume and higher pressure mean more shots per fill; always fill through a rated fill station and never exceed the stamped pressure.
How should I store the tank?
Store it depressurized or at low pressure, upright, in a cool place away from direct sunlight, with the valve protected from knocks. Never store a tank in a hot car — heat raises internal pressure. Have the tank inspected and hydro-tested at the intervals stamped on it.
Any safety notes?
Treat every HPA component as pressurized equipment: inspect threads and O-rings before each use, never use damaged fittings, and depressurize the rig before disconnecting lines.
What warranty and shipping cover this item?
It is covered by the Airgrix 30-day limited warranty and ships from our California warehouse. At $199.99 it qualifies for free US shipping on its own (free on orders $59+). Returns are handled under the store returns policy — see our Ordering, Shipping & Warranty FAQ page for the details.
