Jetted tub identification (or at least how to remove jets)?

[HerronScott]

Would love help identifying a jetted tub manufacturer or at least confirm how to remove the jets in order to replace them (gold!).

What I've found searching points to using channellock pliers and twist counterclockwise to remove most types.

Thank you for any help you can provide!

In case anyone else runs into this, I found that these are Balboa 10-3955 and are just covers with the ball jets and unscrew counterclockwise (not the entire jet assembly).
