Thanks for the clarification. Now, lets check for understanding...the PDF for the Victor VTS 250 series indicates the following:
Is the working pressure of the manifold you mentioned, the range I see in this picture? For example, the 250C has a range of 4-80psig and the 250D series has 5-125 psig.
If my understanding is correct, a lower gauge that goes up to 100psi may work for both of these series since, for our purposes, we will never go past the 100psi?
In other words, can a 100psi lower gauge be installed on a 250D series or is a 200psi a best choice?
