UT Twist Fingerstock Gasket
UT Twist Fingerstock Gaskets are engineered to provide reliable EMI shielding, electrical grounding, and conductive contact in demanding electronic applications. Manufactured from high-performance beryllium copper, these gaskets deliver exceptional spring properties, long service life, and consistent electrical conductivity.
The UT Twist profile features a unique twist-style finger design that creates multiple contact points across mating surfaces. This configuration helps maintain electrical continuity while minimizing electromagnetic interference and radio frequency interference in electronic enclosures, cabinets, access panels, and communication equipment.
UT Twist Fingerstock Gaskets are commonly used in aerospace, military, telecommunications, medical devices, industrial controls, and high-performance electronics where reliable EMI shielding and grounding are essential. Their durable construction allows them to withstand repeated compression cycles while maintaining excellent shielding effectiveness.
