Another Old Scubapro Tank ID Question

[mahjong]

From the 1987 Scubapro catalog, which a friend just looked up for me:

Volume: 75.8 cubic feet at 2640 psig


Length: 26.18 (+/-) .20 inches without valve


Diameter: (outside) 6.76 (+/-) .05 inches


Weight: (nominal): 31.0 pounds with out valve


Material: 4130 X Heat Treated Steel


Working Pressure: 2400 psig + 10%


Coating External: Hot Dip Galvanized


Buoyancy: (calculated nominal w/o valve -5.5 pounds full (+10%) / -0.13 pounds empty (calculated nominal w/o valve in seawater)


D.O.T 3AA approved.

I have 2 sets of these as doubles; friggin' awesome tanks. I got them new in '88 I think and have done a lot of diving with them. Not real heavy, easy to fill.

Well here in the States that's still called an lp85 at 2640psi which is the plus rating for 2400. And yours are/were plus rated. At 2400psi it holds about 78cf.

People have sold/marketed Faber mp72s (3000+ psi) and fx72s (3442psi) here in the US but there's no "75.8" Those are the cubic foot sizes between lp85s and lp50s going back to way before the born date of your cylinders. The Italian translation of cubic foot is a bit off.

That would be incorrect! I've got a twinset of these 76 cu. ft. Scubapro (Fabers) painted Black. Also have a twinset of OMS (Faber) LP 85's ...as well as a 'single' OMS (Faber) LP 85 (all battleship grey). If you stand them side-by-side you can definitely see they are distinctly different tanks. Both tanks are '+' rated from the factory, meaning @ 2640 psi they hold 76 and 85 cu. ft. respectively.

Curious what kind of manifold and bands you use to double these up?

Is the valves 7/8 or 3/4 threaded? Also for those with these tanks doubled, what cylinder band size do we use to double them up?

 

[SeaCobra]

For my double I have OMS 7" bands and the older style OMS isolation manifold (face o-ring seal. any threaded isolation manifold would work. When I first had them as doubles i had the old sherwood single outlet benjamin manifold.

Do you know the C-to-C spacing on that Sherwood manifold? I have a few old single outlet Sherwood Selpac manifolds, a couple new and never used (one with the metal turn knob)--they are J Valve, but modular, so I can replace the J Valve with a plain elbow valve. These are all so-called nipple-to-nut valves, non adjustable, so the spacing of the bands has to fit the manifold perfectly. The spacing on these old Sherwood manifolds is less than today's standard of 8.5"--so the 7" OMS bands are also less than 8.5", I take it (I can't recall the exact C-to-C spacing of the old Sherwood manifolds, somewhere around 8.25" I think)?

For my double I have OMS 7" bands and the older style OMS isolation manifold (face o-ring seal. any threaded isolation manifold would work. When I first had them as doubles i had the old sherwood single outlet benjamin manifold.

I am going to give this old thread a bump as I too have a couple of these cylinders thanks to a SB member. Mine are from 1992 and are not galvanized but have the triple coating that Faber is known for. Like many cylinders they do not have the REE values stamped on them. However, Bud Allen from Blue Steel, the North American distributor was able to supply me with the REE values (REE 64). I have the email, which was good enough for my local hydro shop to use for the re-equal test. If you have these cylinders I am happy to share the email with you in the hopes that it might assist in getting the plus stamp for the next hydro.

I am looking for a set of these. Anyone looking to sell?

I recall someone on this thread was looking for a pair of these tanks. I have 4 available on this post:
