CEFIL’AIR® Inflatable Seals
CEFIL’AIR® Inflatable Seals
Pneumatic seals offer the easiest, safest and most effective way of sealing parts that move in relation to one another and need to be connected and disconnected. CEFIL’AIR® seals, which are expanded and retracted by a pneumatic process, feature a patented design that employs advanced elastomers and modern manufacturing techniques to meet the requirements of numerous applications.
BIO-GUARDIAN® SEALS: essential to the medical, pharmaceutical and food industries, the BIO-GUARDIAN® sealing solution prevents bacterial and microbial growth on equipment and materials. The BIO-GUARDIAN® solution can be used in CEFIL’AIR® inflatable seals to meet the needs of demanding hygienic applications.
Features & Benefits
- Expand and retract with movement of fluids (pneumatic or hydraulic)
- No seal stress during opening and closing phases
- Large material selection: Silicone, SBR, EPDM, FKM, HNBR, which offer highly resistant mechanical and physical properties to ensure a long lifetime and numerous operating cycles
- Highly flexible design: available in a large selection of shapes and sizes
- BIO-GUARDIAN ® elastomers prevent the development of bacteria and biofilm formation
- Laser marking for complete traceability
- RFID chip can be included for traceability & reliability
- Can be used for moving, handling, holding or clamping, particularly large, fragile or complex objects
Product Applications
- Movable cofferdam bulkheads
- Storage and transport containers
- Leak-tight panels (naval, aerospace industry)
- Nuclear vessels (equipment or personnel chambers)
- Isothermal chambers
- Clean rooms
- Phonic isolation
- Sliding or quick-locking doors (autoclaves, sterilizers)
- Centrifugal filters (access doors and drainage hoppers)
- Aircraft access doors
- Cockpit canopies
- Portholes
- Cofferdams
- Pneumatic conveyors (bagging hoppers, valve gates)

Machined Metal Seals
Machined Metal Seals
Technetics offers a diverse range of machined metal sealing solutions for extremely demanding environments. We can design and manufacture from any machinable material at our state-of-the-art manufacturing facilities that are equipped with machining centers and coordinated measurement systems to ensure world quality precision.
Features & Benefits
Benefits:
Machined metal seals are designed to meet applications with high temperatures or cryogenics, high pressures, full vacuum, very corrosive chemicals and penetrating levels of radiation.
Unlike formed metal sealing solutions, machined seals do not require tooling to be developed, reducing this associated cost and lead-time.
During rapid development, programming for machining for modified parameters requires much less time than tooling modifications required for formed seal solutions.
Suitable for applications that require a metal seal that is difficult to manufacture in certain sizes or require a special geometry profile.
Features:
- Platings and coatings: silver, gold, nickel, PTFE
- Extremely corrosive and radioactive environments
-
Pressure up to 241 bar (3,495 PSI)
-
Temperature up to 1,200°C (2,200°F)
- Suitable for applications that require a metal seal that is difficult to manufacture in certain sizes or require a special geometry profile
Product Applications
- Aerospace Industry
- Space Launch System (SLS) – Technetics provides Boeing with NAFLEX and K-Port seals for SLS liquid hydrogen fuel and liquid oxygen propellant bolted joints and AS5202 threaded ports. The NAFLEX seals ensure the integrity of critical fluid connections during the stress of launch during extremes of high and low temperatures during the mission.
