T205 Series maintains a slightly positive pressure and thereby
reduces the possibility of tank wall collapse during pump out operation.
The T205 Series is available in two configurations: Type T205 for
internal pressure registration and Type T205M for external
pressure registration.
The distinctive Diamond shape cast into every spring case uniquely identifies the products as part of the Fisher brand and assures you of the highest-quality engineering, durability, performance, and support traditionally associated with Fisher regulators.
