These Test Point Plugs are designed to be complementary to
and interchangeable with similar equipment from other
manufacturers using DIN 2353 standards. Plugs are installed into
the hydraulic system hardware and are used in conjunction with DIN
2353 Pressure Test Probe equipment. The equipment is used to obtain
random pressure checks during servicing and fault finding. Probes may be
connected and disconnected at full system pressure without fluid loss or
ingress of dirt.
