High Performance Seals for Extreme Aerospace Environments

Monday, July 11, 2016 by Sealing & Shielding Team

Today’s sealing challenges demand innovative solutions, and nobody knows innovation better than Parker. That’s why Parker develops and manufactures engineered sealing solutions – technologically advanced sealing devices and materials that can keep pace with aggressive chemicals, temperatures, and pressures.

Our sealing products are designed with a unique combination of experience, innovation and support to ensure superior product performance, reliability and safety. Our on-site research laboratories evaluate performance through comprehensive testing processes to meet specific customer needs. And our world-class facilities allow us to formulate and design products to meet the most stringent industry standards (MIL, AMS, UL, and many others) to address aerospace applications calling for extreme high/low temperatures, fluid/pressure resistance, and fire resistance.

Below are just a few of the aerospace solutions the Engineered Materials Group offers in the Aerospace industry.
Image	Product	Value Proposition
	Diamond Seals	Parker's diamond seals, designed for face sealing applications, provide robust sealing with retention while requiring a fraction of the space and load of traditional seals.
	Tadpole Tapes	High temperature, flame-resistant tadpole tapes from Parker are used in firewall closures and structural sealing. Resilient, non-hardening materials can be customized for temperature exposure and bolting force to suit requirements.
	FlexiSeals - Spring-energized PTFE Seals (Air Management Systems)	FlexiSeals® from Parker Praedifa used in cabin air conditioning systems withstand temperatures up to +260°C (500°F), are resistant to dynamic movements and meet the long lifetime expectations of the industry.
	Custom Rotary Shaft Seals For Aerospace	Parker's wide range of rotary shaft seal options provide superior elastomer lip material options for improved wear resistance and enhanced performance. Custom and standard solutons are available in a wide range of elastomeric, PTFE or labyrinth designs for engine, air management, landing gear & wheel and brake applications.
	Custom Expansion Joints	Custom expansion joints from Parker manage movement, vibration and misalignment between ducting and mating surfaces in aerospace air management systems.
	VX065	O-rings made from VX065 deliver the extreme low temperature performance needed at high altitudes and during engine startup. With outstanding compression set resistance, VX065 significantly extends seal life in low temperature fuel applications where traditionally only fluorosilicone could be used.
	FF200	Parker's ULTRA FF200 exceeds AMS 7257C, demonstrating superior retention of mechanical properties and resistance to compression set after longer term fluid exposure and high temperature.
	Metal Seals (Jet Engines)	Metal seals used in jet engines withstand temperatures up to 1100°C (+2000°F) and pressures up to 6200 bar while ensuring extremely low leakage rates.
	Sealing Systems for Hydraulic Actuators (Landing Gear)	Parker Praedifa provides a wide range of sealing systems for hydraulic actuators providing excellent compatibility with common aerospace fluids and withstanding temperatures down to -50°C (-58°F).
	VMQ, PVMQ Extruded Profiles	Parker's expertise in custom extruded and spliced seals enables highly complicated geometries and shapes such as 3-D, multi-corner and compression-limited gaskets, while providing superior high bond integrity. This customized solution does not require tooling, and the seals are devoid of parting lines, flow lines, flash and void.
	Fabric Reinforced Products	Increase material strength with low closure force sealing to create a variety of products including bellows, profile seals and aerodynamic seals.
