End caps are necessary parts in every stainless steel tube installation on your boat. All sprayhood/dodger, bimini and solar panel frames have them. Normally in every joint between tubes.
For fail-safe installation we suggest to rivet the end-caps to the tube using only AISI316 stainless steel rivets. Use blue Loctite to lock the screws, if riveting is not possible.
