NOTE:
The element life is based upon cleaning cycles and pressure drop. The estimated life of the element is 10 to 15
cleaning cycles. If the element has exceeded this level discard and replace.
The proper way to evaluate your element after cleaning is an ARP-901 Bubble point test. Contact factory for any
cleaning or testing requirements.
Recommended cleaning fluids are acetone, mineral spirits and a variety of others. Halo-carbon grease or Krytox
are recommended lubricants. Other acceptable lubricants include petroleum jelly or silicone. Caution should
be used when using dry lubricants, due to the fact that our threads are single point, precision threads and dry
lubricants can disrupt clearances.
