The Dominator International HPA QD Coupler (DS-U00300) provides heavy-duty, leak-free quick-disconnect connectivity for high-pressure air (HPA) systems. It is designed for demanding airsoft platforms, paintball markers, and custom compressed air lines, and built for long-lasting durability.
Precision-engineered to rigorous field standards, this fitting minimizes flow restriction, for reliable cycle rates and consistent output shot after shot.
Key Features
- CNC Precision Engineering: Machined from premium metal alloy for exact tolerances and secure thread engagement.
- High Working Pressure Tolerance: Built to safely handle high dynamic pressures without leaking or failing.
- High-Flow Internal Design: Smooth internal geometry minimizes air turbulence, for consistent velocity and air efficiency.
- Corrosion & Wear Resistance: A protective surface finish resists oxidation, dirt, and moisture during intensive field use.
- Universal HPA Integration: Compatible with standard HPA regulators, remote air lines, manifolds, and tank adapters.

Frequently Asked Questions
What is this used for?
The Dominator HPA QD Coupler DS-U00300 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 should I check before ordering?
Check the fitting type and thread against the rest of your rig (regulator output, line, and gun-side adaptor). Quick-disconnect fittings are convenient, but QD patterns and thread standards must match across every component in the line.
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. It counts toward the $59 free-US-shipping threshold. Returns are handled under the store returns policy — see our Ordering, Shipping & Warranty FAQ page for the details.
