Item Stopcock Bore CS-S540004 0-4mm CS-S540008 0-8mm 0-4mm adjustable high vacuum valve plug designed with precision control knob and premium PTFE stem. Equipped with three durable Viton O-rings for superior tight sealing and long service life. Featuring excellent chemical resistance and stable vacuum flow control performance, this reliable PTFE vacuum plug is widely used for precise gas flow regulation in various laboratory high vacuum systems.
Detailed Product Description
Premium PTFE Stem & Humanized Control Knob
This high vacuum valve plug adopts high-purity PTFE stem as the core working component, featuring excellent chemical corrosion resistance, self-lubricating property and non-contaminating performance. It can resist erosion of most acids, alkalis and organic reagents, ensuring no sample pollution during experiments. Matched with a professional control knob, the valve supports smooth and flexible manual adjustment with no jamming, enabling precise stepless flow regulation to meet diverse experimental parameter requirements.
0-4mm Precise Adjustable Range
Featured with a standard 0-4mm adjustable stroke, this vacuum valve plug achieves high-precision vacuum flow control. It can accurately adjust and stabilize the gas flow rate and vacuum pressure inside the pipeline, effectively solving the problems of unstable air pressure and uncontrollable flow in laboratory vacuum experiments. It perfectly adapts to fine adjustment scenarios of high vacuum systems, greatly improving experimental accuracy and repeatability.
Three Viton O-Rings Enhanced Sealing Performance
Different from ordinary single-ring vacuum valves, this product is equipped with three high-quality Viton O-rings for multi-layer superimposed sealing. Viton material boasts outstanding high temperature resistance, wear resistance and aging resistance, far exceeding ordinary rubber rings. The triple sealing structure provides ultra-tight airtightness, effectively preventing vacuum leakage, gas overflow and pressure loss, maintaining long-term stable high vacuum working environment and greatly extending the service life of the valve plug.
Stable & Professional Lab Vacuum Accessories
Integrating PTFE corrosion resistance and Viton high-performance sealing advantages, this high vacuum valve plug combines sturdy structure, flexible adjustment and durable sealing. It is not easy to deform, age or leak after long-term repeated use. The overall design is compact and practical, easy to install, disassemble and maintain, which can effectively reduce laboratory equipment replacement costs and improve experimental efficiency.
Wide Application Scenarios
This high-performance vacuum valve plug is widely applicable to chemical laboratories, environmental testing, pharmaceutical research, university scientific research and industrial laboratories. It is an essential core accessory for vacuum pipeline systems, vacuum reaction equipment, vacuum distillation, vacuum degassing and vacuum concentration devices, suitable for all high vacuum experimental scenarios requiring precise flow control and high-standard sealing.
