got a 5/16 hose i'm trying to hook up to a female swivel port, would this fitting work for that?

Answer by: Customer Support on Feb 8, 2026, 6:44 AM

A 0.313 inch hose ID lines up with a 5/16 inch hose, so yes, that barb end should fit your hose. The swivel end is a 1/4-18 NPSM female thread, so as long as your port matches that thread spec, you're in good shape for a low pressure fluid transfer or suction and discharge setup.

got a 5/16 hose, is this the right barb size for it?

Answer by: Customer Support on Mar 6, 2026, 7:09 AM

For hose fit, it matches a 0.313 inch hose ID, which is the same as 5/16 inch, and it’s a short shank hose barb style.
