Sterile Inflatable Seals for Medical Devices

Reliable, Contamination-Free Sealing for Critical Healthcare Applications

Medical devices demand sealing solutions that meet the highest standards of cleanliness and regulatory compliance. Our sterile inflatable seals for medical devices deliver on-demand pneumatic sealing that ensures sterile integrity throughout every operating cycle.

How Inflatable Seals Work

An inflatable seal expands when pressurized, creating uniform sealing force. When deflated, it retracts fully into its groove, allowing doors and access ports to open and close without friction or wear. Unlike traditional gaskets, it generates its own sealing pressure, compensating for surface irregularities and thermal expansion.

The Cleanroom Inflatable Seal Advantage

A cleanroom inflatable seal provides the reliable barrier that pharmaceutical and medical environments demand. Manufactured from platinum-cured silicone in ISO Class 7 cleanroom conditions, it features low outgassing and easy cleanability. When deflated, it retracts completely, presenting a smooth surface with no crevices for contaminant accumulation.

Vacuum Chamber Inflatable Seal

Many medical devices are manufactured using vacuum processes. A vacuum chamber inflatable seal ensures reliable vacuum integrity in thin-film deposition, plasma treatment, and freeze drying. Low-outgassing silicone formulations minimize contamination, while instant deflation allows quick chamber access.

Food Silicone Inflatable Gasket

A food silicone inflatable gasket provides reliable sealing for food processing and pharmaceutical equipment. Made from FDA-compliant silicone, it withstands repeated SIP and CIP cycles. The inflatable design ensures a uniform seal even on irregular surfaces.

Key Benefits

Contamination-Free Sealing – Uniform pressure ensures a reliable barrier against particles and microorganisms.

Extended Service Life – On-demand inflation extends seal life 3-5x.

Easy Maintenance – Deflation creates immediate clearance for inspection.

Regulatory Compliance – FDA 21 CFR 177.2600 and USP Class VI compliant silicone.

Applications

• Pharmaceutical isolators and RABS systems

• Medical device sterilization equipment

• Cleanroom doors and pass-through chambers

• Vacuum chambers for device manufacturing

• Freeze dryers and lyophilizers

Installation Guidelines

Grooves require rounded edges (min. 1 mm radius). Use regulated air or nitrogen from 0.1 MPa, gradually increasing to 0.2–0.4 MPa—never exceeding 0.6 MPa. Apply silicone grease during installation.

Quality Assurance

Every seal undergoes 100% visual and dimensional inspection. Optional helium leak testing and full material traceability available. FDA and USP Class VI certifications available.
