Contrast Injection Stopcock
High-pressure rated 3-way stopcocks for contrast media injection in CT, MRI, and interventional radiology. Clear polycarbonate for visual confirmation. Power injector compatible.
About Contrast Injection Stopcocks
During CT, MRI, and angiographic procedures, contrast media is injected under pressure using power injectors. Standard IV stopcocks are not rated for these pressures and can fail, causing contrast extravasation or procedure interruption. Contrast injection stopcocks are specifically designed and rated for power injector use.
Key Design Features
- High-pressure body — reinforced polycarbonate construction rated for power injector pressures
- Clear body — full transparency for visual inspection of air bubbles before injection
- Luer lock only — threaded connections prevent accidental disconnection under pressure
- Large bore — minimizes resistance and allows high flow rates needed for contrast bolus
- Chemical resistance — compatible with all common contrast media formulations
Typical Applications
- CT angiography (CTA) contrast injection
- MRI contrast administration
- Cardiac catheterization and coronary angiography
- Peripheral angiography and vascular interventions
- ERCP and other endoscopic contrast procedures

Frequently Asked Questions
Yes. Our high-pressure contrast stopcocks are manufactured from reinforced medical-grade polycarbonate and designed to withstand the pressures used by CT and MRI power injectors. Pressure rating is confirmed during design and testing phases.
Clear polycarbonate allows the clinician to visually inspect the stopcock for air bubbles before injecting contrast. Air embolism during contrast injection is a serious complication — visual verification of an air-free connection is an important safety check in radiology practice.
Yes. Port angle, handle position, and tubing connection dimensions can all be customized for compatibility with specific power injector tubing sets and your clinical workflow.
