Dents May Cause Cracks
ISO Particle Count Cracked filters can be caused by dents
made during improper installation of liquid Shoptalk
filters. Filters that are dented prior to or
during installation should not be used. Filters
dented after installation should be replaced
Sampling Pump (P176431) &
Plastic Tubing (sold separately immediately. The cost of replacing a dented filter
in 100 ft. rolls) is much less than the cost of the damages that
could result from a dented filter that fails during
service.
The fatigue to filters results from the pressure
pulses within the system. The pressure is
regulated by a pressure regulating valve. This
valve is spring operated and intermittently opens
and closes to regulate the pressure. Once the
pressure exceeds the setting of the spring in the
Kit X007377 for basic hydraulic oil analysis regulating valve, the valve will open and relieve
pressure until the spring can expand and close Filter Maintenance Kits

during the operation of the system, creating
a pulsing effect. The canister of the filters is
