I just used car grade inner tube, punched a hole in the middle and bolted it back together. It works great, has held 40psi with no issues.

yes you can buy just a diaphragm from NGR. They sell them for $40.00

I know this is a old post but I have a greddy rs bov and i contacted ngr yesterday. They told me that the ngr diaphragms will not work in the greddy rs bov. Im not sure if that applies to the type s or not.

NRG copied the diaphragm design from the GReddy Type-S, they just use better material.

Here's GReddy's part numbers.

Notice how the same diaphragm is used for Types RZ, RS & Type S BOV's.

You make the call.
I'll be buying a NRG diaphragm for my Type RS when this one sh!ts the bed...
