Seneca / Sam Yang / Sumatra Replacement Fill Probe

I own a Sam yang 50cal Dragon claw I have the single air tank under the Barrel that takes the Male fill port connector. This part looks like the one that came with my Dragon Claw the fill port is 3/8 of inch in diameter. I would like to confirm with tech support if this is the right fill connector for my gun. Thanks for any help help if it the right one I will be buying it.

Will this work with my XISCO Sentry HC Deluxe 705-2

Since I'm new to air rifles I didn't know mine would not come with a fill probe. I had to buy a pump separately that also didn't come with a fill probe. My question is, will this probe fit my Hatsan BT Carnivore QE SL? If it will not fit can you tell me which of the fill probes will fit the Hatsan BT Carnivore QE SL? Thank you.

Will this fit on a flashpup

is this steel or stainless steel

Does this probe fits in the saver rifle?

Does this probe match Diana stormrider?
