sewer line upgrade - need to replace cap and sewer hose

I'm trying some sealant spray on one of our hoses that leaked from day one. I'll let everyone know if it works. I connected our cap with a length of 1/16th inch cable that is too short to let the cap drag if forgotten.
As for brands I favor Rhino right now because of the way it collapses and stays collapsed.
For caps whatever appeals to you, Camco is the most common.
