Camloc on hybrid

Unread postAuthor: PeteS » Sun Dec 01, 2013 8:26 am

I have been pretty happy with my 1" EMT barreled hybrid, but want a bigger bore so I am building a 1-1/2" EMT barreled hybrid. The union I used on the 1" one has worked well, but I have to carry big channel locks to tighten it enough to avoid leaking at the burst disk. So I am planning to go with a camloc on the new gun and may retrofit the existing one that way as well.

I see that the camlocs are generally rated at 250 psi for the aluminum, brass, or stainless ones. I have a hard time believing that the stainless ones are not capable of much higher pressures than the aluminum. Is it a design issue that limits the pressure rating, like maybe an issue with the seal? Is the rating just kept at 250 because the usage they are typically applied to doesn't require more?

I see that the stainless ones are a lot more expensive so I guess I'd rather go cheaper. Is there any reason to spend the extra money for stainless on a gun that will probably be used mostly at 4-5X and might possibly be fired at 8x or so,

Given the fact that in a hybrid it only has to tolerate high pressure for a brief instant, being a bit nonchalant with rated pressures is not likely to cause injury. The worst that can happen is that your barrel will blow out :D

Oh, one other thing...

I see folks using camlocs with the male fitting on the barrel and others with the female fitting on the barrel. Is there any reason it matters which way you do that?

250PSI is simply the maximum pressure the manufacturer guarantees they will function at, leak free, for the life of the fittings. I don't think that rating is based on any particular safety factor, and it doesn't necessarily say anything about how much stress they will withstand before undergoing mechanical failure. You should be fine at 8X using aluminum, brass or stainless steel.

The fitting that houses the seal, typically the female, should be mounted on the chamber, unless you're using some kind of alternative seal setup. It's more of a priority to have a leakproof connection between the chamber and disk than the disk and barrel.

I have used the black composite "plastic ones" with no trouble. Obviously metal would be much safer and superior of a material. I usually put the female on the launcher as, males are cheaper. You can then attach multiple barrels paying less for each adapter. Also, it seems a bit less clunky with the male on the barrel. It's cleaner to make a breach loader that way also.
