wtb 4 inch round pressure gauge

[mtkst19]

i am looking for a pressure gauge for my tire machine. 4 inch round flange mount style. has a back side feed to it. figure 0-100 or 0-200 psi is fine. most tires will seat by 50 psi. but there have been a few scary ones that need more pressure... the stock broken gauge reads to 200

thanks in advance
