PYI Seaview Cable Glands, even a Retrofit model
Ben Stein’s cabling frustrations reminded me about the value of good cable glands, like the selection from PYI Seaview. They are designed so that you can pass a cable with a fair sized connector — or even several such cables — through a deck or superstructure, but end up with a tight waterproof seal around the cable(s).
PYI offers Seaview Cable Glands in anodized aluminum, polished stainless, and even custom finishes, but I’m fine with this less expensive ABS plastic multi cable model. When it’s eventually installed behind the radar and hailer speaker on the front of Gizmo’s flying bridge, it will hardly show anyway, and it could nearly disappear with some white paint.
Aesthetics aside, this cable gland should be able to seal at least the existing cables, no problem, with room for more (as long as the connector diameters are less than 17mm). PYI provides clear instructions — and even produced a thorough install video — so I’ll just note that the white part above will end up permanently screwed to the flybridge (with gasket) , through which I’ll drill/cut a hole about the size of the oblong cut out.
The trickiest part is drilling and slicing the rubber plug to fit the cable size(s), but it’s not too tricky and there are various ways to manage mistakes (like rescue tape). The design is forgiving because the tapered plug gets evenly squeezed when you tighten down the gray cover with the four machine screws (and easily redone).
In fact, this cable gland will replace a Blue Sea Cable Clam that was only meant for one cable, but hasn’t leaked in several years of use with two. The Cable Clam uses a similar tapered and compressed plug design, as do a wide selection of Scanstrut Deck Seals. (And I can testify from hands-on experience that all three brands are well made.)
But to my knowledge, only PYI offers Retrofit Cable Glands, which could a blessing in situations where you can not easily remove the cable. Note how two dovetail joints are used to firmly lock the base together so it can withstand the pressure of the tapered rubber sealing plug. Clever!
