What Length Manifold?

[Ouvea]

Hi Guys:

Going to take GUE Doubles Primer and need to setup my tanks. I'm using mid pressure Faber steel tanks with an outer diameter of 6.9 inches. I have found bands from Piranha Manufacturing, which will work with my tanks. Can anyone tell me what length manifold I need to purchase? Also, are there any real differences (durability wise) with valves from Thermo/XS Scuba, Dive Rite, Pinanha Mfg or OMS?

Thanks,
O.

Centre to centre should be 8-8.5inches. I dont know the brand you mention, but Highlands is the best in the business. I know Divegearexpress have the 3inch wide bands on special.

Valve wise I only use DIR Zone. Once again IMO they are the best. Some reading if you are interested www.scubaboard.com/forums/tanks-valves-bands/465828-halcyon-valves-manifolds.html

Definitely check. The most common manifold is 215mm/8.46" but a 190mm/7.48" is available form a few suppliers like Pinanha. Bands and manifolds have to play nice together. There are also a few bands around for 6.9" cylinders that are made for the pre-isolation manifold days (old steel 72s) that don't fit either manifold.

Either width, I recommend a manifold that is DIN and Yoke convertible to keep your resale options open. You also have to order the right manifold for the pressure rating of the cylinders you are installing them on so the blow-out disks are sized right. Disks can be changed of you change cylinders later.
