Around the world, designers of commercial and military aerospace and defense systems trust Bal Seal Engineering’s springs and seals to protect critical equipment from leakage and potential failure. Our products help make equipment smaller, lighter, faster, and more power efficient.
Products for Aerospace & Defense
Bal Seal® Spring Energized Seal
Our seals are precision-machined from PTFE and other premium polymers, and they’re engineered to deliver longer service life and more equipment uptime. Their spring energizers ensure even, consistent wear, and their jacket materials can be customized to meet specific temperature, pressure, speed and chemical compatibility requirements in rotary, reciprocating, oscillating, and static applications.
- Controllable friction forces
- Excellent media and temperature resistance
- Wear-regulating spring energizer
Bal Spring® Canted Coil Spring
Our spring mechanically fastens, conducts electricity, and shields sensitive electronics from EMI/RFI. Its independent coils, which serve as multiple contact points for optimal current carrying capability, ensure consistent, reliable connection—even under shock and vibration. The spring can also serve as a thermal management component.
- Superior conductivity & power density
- Compact, space-saving profile
- Multifunctional for lighter, simpler designs
- Customizable insertion/removal forces
