I'm looking for a grease with at least 10% Teflon, preferably much higher that is compatible with Aluminum and polymers like Viton and Buna. We have found a grease that fits this bill but it 's very expensive, $21.00/ounce. Just to make things even more difficult, I can’t use a silicone based...
The problem you're talking about is called extrusion. Designs in O-ring handbooks are not made to handle this use of an O-ring. My company makes this type of valve and I can't get into the details of how we handle this situation without violating proprietary technology. What I will say is to...
I have some more questions. What would cf, z and M be for air? I assume the pressures are absolutes as well.
Of course, our Salesman had the question backward from the start. The customer was actually looking to fill the tank not empty it. Is this equation appropriate for that case as well...
I need some help figuring out what size valve I will need to empty an 82.34 cu. in. tank of air at 120 psi in .45 sec. I can take formula for the relationship between pressure, volume and flow rate and size the valve myself, hopefully.
Thank you for your assistance.
From someone who works for manufacturers of these type devices, we never say a given rubber will work in an application, especially one like this. Not because we don't have detailed knowledge of what chemicals a given rubber is compatible with but we have no way of knowing what chemical it's...
I need to do a proof and burst test on an assembly. The pressures are 700 and 2100 psi respectively. Does anyone know of a laboratory in the Northern New Jersey are that can perform such a test?
Thank you, TVP. I appreciate your expertise.
I have contacted our vendor. (What I should have done in the first place.) He informed me that our part was too large to be half hard and parts this size are 'as cast'. How much does the material properties of brass vary in the 'as cast' state...
C360 Half Hard Brass is what is on the print. We got in C36000 Cast and Turned. I was able to find info on C36000 but haven't been able to find anything on C360 Half Hard. Can anyone provide me with the specs on C360 Half Hard?
Thank You.
