The aerospace industry needs robust sealing solutions, ever reliable and highly engineered. They need Advanced_EMC_Aerospace_polymer_plastictechnologically advanced sealing devices that can withstand aggressive chemicals, variegated pressures and high temperatures. Top standard sealing products combine experience, engineering and innovation. These are cost effectively, yet efficiently built, to fit virtually any aerospace application.

Sealing solutions have to stand aggressive chemicals including jet fuels, hydraulic fluids, solvents/degreasers and engine lubricants. Other factors they have to work with are Elastomer temperatures to 320C (608F); Metal seal temperatures to 1,093C (2,000F); High frequency oscillations; High and low pressures ranging from 20,000 psi to vacuum; Weightlessness; Continual threat of fire and explosion; and varied applications including dynamic, static and rotary.

Manufacturers of sealing solutions have to keep innovating for changing market environment as well. Commercial jets are likely to trade speed for size and onboard computer to make radar obsolete, integrating aircrafts, pilots and ground control. New generation jet engines may enable continuous flight in excess of 18 hours. Demands for safety, comfort and service life is likely to go up. Experts also expect structured cost cutting and continued development of advanced composites for improved fuel economy and weight reduction. Industry is also moving towards intensified globalization of customers, manufacturing and supply.

The industry needs a slew of sealing solutions for different applications. Integral seals bond the elastomer to engineered plastic retainer plats and thin metal allowing for complex sealing geometry and ease of assembly. Fastener seals provide static sealing for bolts, screws and other such components. Dynamic seals provide for critical low duty cycle and all metal sealing for mission critical applications. These seals perform outstandingly under extreme environments.

Metal seals and gaskets come in a wide range of base metals for high vacuum, high temperature, low extractable and broad chemical resistance applications. PTFE seals are designed for rotary 10applications. It is available in single, dual and triple sealing lip designs providing for wide temperature range, high speed capability and chemical compatibility.

Custom-molded seals come in a virtually infinite range of shapes and cross sections. These are available in engineered elastomeric shapes, both inserted and homogeneous, for applications. Backup rings are manufactured for solving an existing seal extrusion problem or safely increasing system pressure.

Spring energized seals are used in applications where elastomeric seals fail to meet the frictional, temperature or chemical resistance requirements. These are used on rod, piston, rotary and face sealing apps. Ultra high temperature metallic seals provide for higher efficiency and reduced emis11sions. These seals are meant for combustion chamber, power turbine and compressor.

Seals used in aerospace industry can also be used for electrical grounding and shielding, actuators, fuel systems, pneumatic systems and gear systems. Reliable manufacturers can customize seals according to the clients’ specific requirements. Their engineers will discuss with the clients their requirements and then come up with a solution. Factoring in the rigorous use of seals, the manufacturers take care that their product line meets the most demanding requirements. All seals are sophisticated enough to deliver as expected. Environment notwithstanding, the components can perform precisely.
