At Perfect Engineers, we design Quick Release Couplings (QRCs) to meet the precise pressure requirements of various industries. Whether you need a coupling for light-duty compressed air systems or heavy-duty hydraulic lines operating at 15,000 PSI, our range of pressure-rated QRCs ensures durability, safety, and leak-proof performance.
Every QRC must match the system’s working pressure to prevent accidents, leaks, or mechanical failure. Choosing the wrong pressure rating can result in system downtime, fluid loss, or severe equipment damage.
| Pressure Rating | Application Example |
|---|---|
| 1500 PSI | Air tools, pneumatic lines, washdown hoses |
| 3000 PSI | Lift gates, mobile hydraulics, test lines |
| 6000 PSI | Mold machines, agricultural equipment, heavy hydraulics |
| 10000 PSI | Oilfield equipment, high-pressure power units |
| 15000 PSI | Rescue tools, offshore valves, fire-safe actuators |
