Question by: Bobby C on Aug 7, 2025, 11:36 AM
both ends on this union are female, right? trying to figure out if it'll work as a straight connector between two hose lines without needing extra fittings
Answer by: Customer Support on Aug 9, 2025, 6:57 AM
Correct on both counts. Each end is a female line/hose/tube connection, so it functions as a straight union joining two hose or tube runs together. No additional adapters needed for that kind of inline connection. The 1/2-inch size applies to both ends, so the lines coming in from each side need to match that dimension.
