Sharp objects! The needles in the needle assembly are sharp and present a risk of injury due to penetration and/or
laceration. The needles are in direct contact with the process media and may have residual substances on their surfaces.
These substances may exacerbate an injury.
The needle assembly can be removed and replaced by removing the shroud and a single retaining nut. The needle assembly
is equipped with o-ring seals around the fluid inlet port and the needle assembly. The area between the seals is vented to the
assembly vent connection. This arrangement provides maximum protection from potential leakage as fluid leakage resulting from
a defective inlet seal is diverted to vent rather than discharge to the atmosphere. The needle assembly has positive engagement
to insure that the needles are correctly positioned prior to insertion.
