Apeks 1st stages

[ian Price]

A question? (which may be daft)

the LP ports on my first stage are different sizes between my main reg and my octopus. Is there a reason for this???I'm in the middle of swapping stuff over so I have 1 5ft reg. (donating this in emergegencies) With my auto-air, (and pony reg) as my back up.

Again if any one has hints tips or things to watch out for I would be grateful..

The reason given is that it allows a greater flow of air, but i am not sure if it actually does. Of course it also means you have to carry two spare reg hoses, or an adapter, if you can find one.

I never found it different even if you do conect a reg to the "smaler" port

Had the same problem.

I elected to convert my original to Din which kept the hose/connection which I use as the backup reg.

I bought a new Ist stage (and had the smaller ports) so I used a long hose with a smaller port thread (standard???)

I dont have any probs and as far as I am concerned air delivery is not impacted.

Thanks for the help and info..

I believe you can get an adaptor to make the large port smaller

Or if you are uneasy about using an adaptor (adding an extra o-ring) you could get a blanking plug for the larger port, which has a 1/2 inch UNF thread. The 'standard' LP ports have a 3/8 inch UNF thread. Blanking plugs can be obtained from Apeks or Sub-Aqua Products.
