DOMETIC SEASTAR 3/8 Inch Tube Tee Fitting, 3-Pack – HF5530
The Dometic SeaStar HF5530 is a tee fitting kit for branching compatible 3/8 inch hydraulic tube lines in SeaStar steering and power-assist plumbing. Dometic power-assist literature lists HF5530 as a 3/8 inch tube tee fitting supplied three per kit.
This fitting should be selected by the required fitting style, tube size, and pipe/port size, not by appearance alone. For steering system safety, verify compatibility with the helm, cylinder, and hydraulic line type before installation.
