Aqualung LP hose O'ring

[Diogao13]

Hi,

I need some help.

Someone knows the size/specification of the item 13: o'ring #8200-11P for Aqualung LP hose. This hose comes with Axiom i3 BCD.

It seems bit different from the other LP O'rings.

Best,
Diogo

My records indicate that it should be a BS1806 011 which has the dimension of 1.78 mm x 7.65 mm. As it is a LP O-ring you should do well with 70 or 80 shore from either NBR or EPDM.

Although I'm fairly confident these will suit your needs, these sizes do not come from an official source, so take it with a slight grain of salt.

Hi Tanks,
I will look for this dimension. I don't know if there is a relevant difference between this o'ring in imperial or metric dimensions. I believe both fits.

Anyway, the original Aqualung seems to be bit bigger than the others I have.

Thank you so much

So whilst the threads are the same, the groove between different fittings do vary
So match the ID of the oring to the groove or go smaller but not in cross section

Before you buy 100 orings of the same size rather than more

Great. I'll do that.
