White acetal Poseidon Jetstream first stage internal component assembly toolset and stacking fixture.

The Poseidon Jetstream First Stage Toolset is used to rebuild the internals of the Poseidon Jetstream first stage by stacking the valve parts, including the valve centre, O-rings, valve seat, internal piston, and main spring.

By organising the components on the tool first, you can smoothly slide the regulator body over the entire assembly in one motion.

How It Works:

Use the smaller rod from the toolset to firmly press the replacement high-pressure seat straight into its designated position inside the regulator.
Using the main fixture base of the toolset, stack the remaining internal elements sequentially in their exact order: valve centre with o-rings, valve seat with o-ring, valve piston, and the spring.
Align the regulator body over the stacked tool fixture and slowly slide the body downward until all components seamlessly mesh into place inside the housing.
Firmly grasp both the regulator body and the base of the toolset, carefully turn the entire assembly upside down, and lift the tool cleanly away.

Works with Poseidon Jetstream first-stage regulator models 3720 and 3790.

The part is used as a fixture for the following parts:
