I would think they are standard size made by Perko and can be found on line or at West Marine,....

What is the vent hose size?

[lhalffman]

On the 4600 SCB they are 5/8"

Just about any marine chandler will have these in stock. The standard size is 5/8" as mentioned by 'lhalffman'. The other size is 1/2" for much smaller boats. Most boats take 5/8".

I suggest also using 3m 4000 sealant because it is UV resistant.
