Where to find a factory that can customize negative pressure isolator inflatable O-rings? Turn to Qingtu Rubber. Dian focuses on the research, production, and sales of inflatable sealing rings.

Vacuum Isolation ChamberAn airtight door (hereinafter referred to as the "door") is mainly composed of the door frame, door leaf, inflatable sealing strip, and inflation/deflation control system. The inflatable sealing strip is embedded in the groove of the door leaf frame. Its working principle is as follows: when the door is opened, the inflatable sealing strip deflates and contracts within the groove. When the door is closed, the inflatable sealing strip inflates and expands, creating a tight seal between the door leaf and the door frame. At the same time, the door is securely locked.

Seal StripCan be used individually or in sets, featuring single-door control or multi-door interlocking capabilities, it is safe and reliable, widely applied in high-level biosafety laboratories, disinfection rooms, isolation rooms, and other hygiene and safety fields. 

Product Advantages:

Utilizes imported high-density inflatable sealing strips for superior sealing performance.

Stainless steel circular observation window.

Interlocked, to prevent erroneous operation.

The door frames feature a matching stud design for easy installation.

The door panels feature a concentric circle design at the four corners, ensuring superior airtightness.

This inflatable silicone rubber seal and its sealing structure feature simple design, easy installation, excellent sealing performance, and the capability for self-tightening in both axial and radial directions. The outer edge of the inflatable seal is equipped with a guide positioning ring. When the upper and lower lips on the inner edge are closed, they form a complete hollow circular ring. Upon inflating the hollow ring with high-pressure gas (or liquid) inside the pressure vessel, it expands outward, developing self-tightening properties in both axial and radial directions. The greater the internal pressure of the pressure vessel, the stronger the self-tightening effect, and the better the sealing.
Qingtu Rubber specializes in the production of inflatable sealing rings for pressure vessels. With years of production and operation, we have accumulated rich experience in the development of inflatable sealing rings and have assisted numerous manufacturers in solving the sealing issues of open-type pressure vessels. When it comes to inflatable sealing, we are the experts. Welcome to call for custom inquiries.
