What Is a Contrast Injection Stopcock?
A contrast injection stopcock is a high-pressure valve used in radiology to control the flow of iodinated or gadolinium contrast media during CT, MRI, and angiography. Unlike a standard infusion stopcock, it is built from reinforced clear polycarbonate so it can withstand the pressures generated by power injectors while letting the clinician visually confirm an air-free line before injection.
EKINSUN produces these stopcocks by medical injection molding for OEM contrast-delivery sets, with the pressure rating, port geometry, and tubing connections matched to your injector system.
Why a High-Pressure, Clear Design Matters
- Power-injector rated — reinforced body withstands CT/MRI injector pressures
- Clear polycarbonate — visual air-bubble check to reduce air-embolism risk
- Chemical compatibility — stable with iodinated and gadolinium contrast media
- Secure Luer lock — threaded connections that hold under pressure
Applications
- CT contrast-enhanced imaging
- MRI with gadolinium-based agents
- Angiography and interventional radiology
- Power-injector tubing sets and manifolds
Customization & OEM
Port angle, handle position, pressure rating, and tubing-set dimensions are all customizable to match your power injector and clinical workflow. We manufacture to your drawing or reverse-engineer from a sample, with USP Class VI / ISO 10993 material options, EO-sterilization compatibility, and an NDA before design review.
Frequently Asked Questions
Clear polycarbonate allows the clinician to visually inspect for air bubbles before injecting contrast. Air embolism during contrast injection is a serious complication — visual verification of an air-free connection is an essential safety step in radiology practice.
Yes. Our high-pressure contrast stopcocks are manufactured from reinforced medical-grade polycarbonate and designed to withstand pressures used by CT and MRI power injectors. Pressure rating is confirmed during design and testing.
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.
Our polycarbonate stopcocks are chemically compatible with all common iodinated contrast media formulations used in CT and MRI, and with gadolinium-based agents used in MRI. Specific chemical compatibility testing documentation available on request.
