WIKA standard pressure gauges are designed for long and reliable service under rugged conditions. Some typical applications are for pumps, hydraulic and pneumatic systems, compressors, as a contractor's gauge, and for many other applications where the measured media does not corrode brass. WIKA standard pressure gauges feature a black ABS case (steel cases are available as an option)and a coiled safety Bourdon tube for 800 psi and higher. The low friction Swiss movement assures a long, reliable service life.
