Aloha everyone,
recently I purchased a nice looking MK5 first stage on an auction site. Upon receiving it, I checked the IP and it had a creep up to around 148 psi. Feeling it was too high, I proceeded to tear it down for a rebuild. To my surprise, the white HP seat face was flat as opposed to the normal concave configuration. So, I replaced it with a Scubapro -1 seat, rechecked the IP and after recycling the IP had a final lock up at 128 psi which is fine with me.
I’ve never seen a flat HP seat in a MK5, so my question is; is this seat correct for Scubapro regulators? Other than not having the concave face, it fits the HP carrier perfectly and looks new. There is no number or markings on the seat. Any ideas?
