The first question that I am seeking assistance in answering is this:
Is it operationally acceptable to install a male 1/2" NPT hose fitting into a female 1/2" #8 SAE/ORB port?
My specific scenario...
I have the following 3 port - 2 way solenoid valve operated by 12V DC:
The 3 ports on this item are sized as 1/2" #8 SAE/ORB
I desire to attach to each port a heater hose fitting like this one:
This fitting's size is 1/2" NPT
Again, the first question: Is it operationally acceptable to install a male 1/2" NPT hose fitting into a female 1/2" #8 SAE/ORB port?
Fluid travelling through the above items will be #2 diesel fuel in a passenger automobile setting.
The second question:
Should anything be applied to the threads of the fittings for the purpose of sealing?
The third question:
For the o-ring that seats into each port of the solenoid valve, should some special kind of o-ring be used or is a generic rubber/synthetic o-ring of the proper size sufficient?
I would sincerely appreciate any offered answers, insight or advice concerning the above. Thank you-
