Where can I buy dive computer O Rings online?...

[jonniex]

I am looking to purchase a few of the O Rings that go on my oceanic data 100 dive computer. i was told that i need: 1 & 3/16 OD, 1 & 1/16ths ID with 1/16th inch thick material.

where can i buy these online or is there a simplified way of tell a dive shop what i need?

thanks!

If you buy at an o-ring shop (actually quite common) just knowing the dimensions is not enough to buy an o-ring. You will also need to know the required rubber hardness or Shore X rating.

For example my Suunto Vyper uses O-ring 1,78 mm x 31,47 mm 70 ShA.

OTOH if you buy at a dive shop you probably won't need to tell them anything except the brand and model of your computer. Of course you'll pay for one what would buy you ten at an o-ring shop.

You can buy o-rings from Leisure Pro, Dive the Abyss, Dive Rite Express, Tech Diving Limited, All O-Rings

The web site at All O-Rings is very informative.

All you need is to know the measurements of your o-ring.

Here is an o-ring sizing chart. You just need some calipers to measure your o-ring and once you know the ID (inner diameter) and CS (cross-section) you can look up your o-ring and order by the "AS568A" number.

Nitrile is the usual rubber. Oxygen compatible o-rings are Viton.

. . . but you will need to know all of the dimensions and properties of the material.

Ace Hardware, 9:45 p.m. the night before departure.

Ace was the place with the helpful hardware man.

For your requirement (water, moderate temps, a couple atm pressure, and static) you have lots of choices and almost any std plumbing o-ring will do the job. Nitrile is probably the best choice mainly from a cost standpoint but viton or epdm (also common in scuba) will perform just as well. Duro 70 should be the correct hardness and is quite common, but there is a lot of leaway on hardness for this application. If it feels about the same as the one you remove (I'm pretty sure that is a Duro 70 nitrile) it should work fine.

That's true, Roatanman . . .
. . . you can even find Viton o-rings at some of them.
