Question by: Randy A on Jul 5, 2025, 8:15 AM
putting lines together in a tight spot, does this swivel union let you clock it without twisting the tube up?
Answer by: Customer Support on Jul 6, 2025, 6:25 PM
With the swivel union style, the fitting can rotate during assembly so you can line things up in cramped routing without putting the tube in a bind.
Question by: Neal J on Dec 22, 2025, 5:52 PM
swivel union 16S -- does that swivel feature actually help when you're routing lines through a tight spot, or is it more just for fine-tuning after the fact?
Answer by: Customer Support on Dec 23, 2025, 7:47 PM
Rotational movement during assembly is exactly what the swivel is there for. When you're working in a cramped area and the tube routing doesn't give you a clean, straight shot, the swivel lets the fitting turn so you can seat it without torquing the tube itself. That takes a lot of the frustration out of awkward installations and keeps stress off the line once everything's locked down.

Will this swivel union work alright in a hydraulic setup that sees some pretty rough use?

Designed with demanding hydraulic circuits in mind, this swivel union has corrosion protection to increase uptime and reduce maintenance costs, so it should hold up well in harsh conditions.
