Question by: Denise M on Mar 9, 2026, 6:08 AM

So this thing's got a female swivel on one end, that right? Makes it easier to line things up, I reckon?

Answer by: Customer Support on Mar 11, 2026, 6:51 AM

That's correct. The swivel female JIC end is designed to simplify installation, especially when you're working with fixed lines or in tight spots. It allows for some wiggle room during connection.
