Remember that the 1/8" is NPT (national pipe thread). This is just the screw size of the fitting you have to use. I assume you are using 1/4" tubing, which is perfectly legal, as long as the inner diameter does not exceed .160".

On another note, why buy solenoids from McMaster? Narrowing down their selection to 12 or 24 VDC solenoids, they are all either low flow or very expensive. If you do buy a solenoid with a working pressure of lower than 120 PSI, you have to have an additional relief valve on your low pressure side set lower than the working pressure of your solenoid.
