I have a pot with a 3/8 ball valve, dropping down into an equal T with a 3/8 bore. Also a pair of regulators with 3/8 ports, hose with ID of 3/8, elbows with 3/8 bore, piping with 3/8 bore.That said the 3/8 male hosetails with 3/8 barb. The barb is much smaller than a 3/8 bore, have I missed something here? I'm thinking the smaller bore could cause a bottleneck to the grit blasting hose and a restriction in the airflow in airline hose? Not made mistake with size of hosetails, they are 3/8 thread x 3/8 barb. Any advice appreciated. Cheers.
