The item in my kit
I bought Half-Inch UNISEAL Tank Adapters as part of my camper van equipment.
I bought the smaller UNISEAL adapters alongside other water-system fittings. My early build plan included the tank openings while the bare interior was accessible.
Where it fits my build
My Day 87 plan put the body openings ahead of the aluminum framing, flooring and wall panels. I specifically included the shower drain and the openings for three water tanks in that order of work.
I removed cargo tie-down hardware to leave mounting points for the extrusion framing, and removed door trim for the later insulation and paneling. SketchUp helped me plan how those separate jobs would fit together.

My build notes
The useful part of this diary entry is the sequence. I wanted to finish the drilling while the interior metal was bare, so later work would not mean opening finished surfaces again.
The photographs show my preceding floor-preparation session. Sweeping, washing and removing residue created the starting point for the interior work I described next.
I planned the openings and mounting access before enclosing the interior.
Alternative products
Two alternatives to compare
The Lifegard half-inch bulkhead uses a rigid fitting and nut. The larger UNISEAL keeps the flexible-seal approach for one-and-a-half-inch pipe, so it represents a different-sized tank connection.
Lifegard Half-Inch Bulkhead Fitting
This rigid bulkhead fitting provides a half-inch connection through a tank wall. A gasket and retaining nut hold the fitting around the opening.
This flexible tank adapter seals around a matching pipe through a prepared tank opening. Its one-and-a-half-inch nominal pipe size identifies the larger adapter in this comparison.
