Can this regulator be configured or adapted to work with 3/8" air lines?

Asked by: mmdyer
Depending on the pressure range of the regulator they have either 1/4 NPT or 1/2 NPT female thread connections on the inlet and outlet. There are no option fittings available. The end user would have to adapted their 3/8" lines to these fittings.
