Mako / Voyager O-ring source?

[nwade]

What's the best / fastest source for a set of o-rings for the Mako / Voyager DPV? :smt026

[Genesis]

I ordered what I THINK is the right "main body" O-ring for the Teknas from Air-oil here a couple of days ago. I'll let 'ya know here once I get them if indeed they really ARE the correct ones once they arrive :lol:

I got mine from Steve Gamble.

Thanks, Moonfuzzy. I'll give them a call. :smt038

If what I've got coming from Air-Oil is correct, however, the price there is all of about a buck and change each..... the "authorized" folks want somewhere around $20 for that O-ring - that's outrageous even by dive-shop standards.

I make my own, the kit is available from Mcmaster.

I was wondering how long it would take you to chime in on this subject! Hey, my first post! Dave, does this mean I'm gonna lose my "lurker" status?

I'd pay 20 bucks to anyone who would promise to drop one in the mail the same day, so I wouldn't have to keep looking at that thing all charged up and sitting on its butt at my house. :smt089

Thanks to all for the suggestions.

Air-oil stocks all this stuff. They will drop them in the mail the same day, and for that same $20 you can have something like 12 of them - with shipping.

I should have the ones I ordered in a couple of days, will compare against the ones I pulled from the Teknas that I'm rebuilding, and if its right, you'll have the correct cross-reference - then you can buy your own, or heck, if you REALLY want one, for $5 I'll toss one in an envelope and send it to you too - that'll still make me something like 300%! :lol:

Thanks, Karl. I found one at Edd's (Cave Adventurers) yesterday. (Now if only I had thought to throw the scooter in the truck before going over to the pond :smt017 )

I have been told that the stiffness of the rubber material can have a HUGE impact on the price of these o-rings. I have a small leak, and was told that getting a $20 o-ring that was much softer than I use would probably do the trick. (BTW - the guy telling me this was not trying to sell the o-ring to me ; )

[Genesis]

The "standard" durometer ratings for O-rings are 70 and 90. You can have darn near anything made up if you're buying enough of them, but the ones that I removed appear to be 70s. I'll see when I can compare against the new ones (they're due her in a day or two.)

[Moonfuzzy]

I belive that 50's were being recommended for the task of fixing my leak.

[Genesis]

50s are really quite soft and would be obvious if OEM spec on nothing more than feel. I don't believe what I have in my Teknas are 50s (main body O-ring) but will see what I've got once I get the replacements.

There's a ying and a yang to O-rings. They need pressure to seal, and up to the point they extrude softer works better. The problem you may be having though could be related to case deformation with pressure or a damaged sealing surface - neither is likely to be helped much by a softer O-ring..... however, it might be worth a try.

I'd probably try to isolate where its leaking first (use some kind of snooping substance in a pool - something like talc), submerge it, take it out, open 'er up and see if you can figure out where the water is coming in. Then inspect that area REAL closely, with magnification (10-30x should be plenty) If you can't figure out where its coming from then just inspect the entire sealing surface - both sides - and see if you can identify any problem areas.

I got mine in 70 dur. Silicone and had it there for 3 years no problems so far. You can get just about any oring that is made I think from this outfit.
Just send them the oring you would like to replace and they will match it up.
