Apollo shoulder dump valve on membrane drysuit – is there an inner port available?

[ZenHscuba]

Hi everyone,

I'm planning to install an Apollo shoulder dump valve on my membrane drysuit.
Does anyone know if there is an inner valve port (backing plate) available specifically for Apollo valves?

I know that Si Tech offers dedicated valve ports like part #60852 for their valves, but I haven't found similar information for Apollo.

Any insights, part numbers, or photos would be really appreciated!

Thanks in advance.

I have an apollo dump valve on my fourth element hydra drysuit. There is no valve port on the inside. The outside port looks very similar to apeks' ones, but not 100% sure they are identical.

Thanks for the information.
It seems that each manufacturer has a different design philosophy, so I’m still not sure which one is the best.

I have disassembled it a couple of times, I'm pretty sure there is a white washer on the inside like on the sitech ones.

Thanks! I do know about the white friction washer.
