HYDAC series 1620, guided piston design, Test Points are compact, self sealing couplings that provide access to hydraulic and pneumatic systems for pressure measurement to 9000 psi. Mating adapters or hose connections can be connected without loss of fluid while the system is operating. Test Points can also be used to take oil samples or to bleed air from hydraulic systems. They are available in 1620 (M16x2.0) connection threads with a variety of screw-in port configurations.
Can be coupled and uncoupled under pressure without system shutdown or fluid loss
Patented guided piston design for leak free performance at operating pressure to 9000 psi
HYDAC guided piston design provides the following advantages over ball seal design: (1) Higher Working Pressure, (2) Better sealing characteristics particularly under high vibration, (3) less susceptible to fluid contamination, (4) can be used for gas as well as fluid.
