All Pegasus stopcocks are produced using high-quality borosilicate glass tubing (SIMAX equivalent or better). Every unit undergoes strict quality control, including inspection of dimensional accuracy, glass integrity, and optical clarity. Each stopcock is individually tested to ensure it is leak-free and ready for dependable use.

We offer a range of standard sizes including 12.5 mm, 14.5 mm, and 18.8 mm, available with both glass and PTFE plug options. Our lineup includes a variety of configurations such as straight, 2-way, 3-way, and Y-bore designs, with options for standard ground joints (SJ) or hose/tube connections to suit your application.
