AlpackaRaft Pack-A-Pump Adapter — Top Up Your Seat and Backrest Without Leaving the Boat

🇯🇵 日本語 | 🇺🇸 English

The Pack-A-Pump threads directly onto AlpackaRaft’s main valve. But AlpackaRaft’s inflatable seat, backrest, and foot brace use a different system — a twist-seal inflation tube that the Pack-A-Pump can’t reach on its own.

The Pack-A-Pump Adapter bridges that gap. Connect it to the Pack-A-Pump, and you can top up your inflatable accessories after tempering without stepping out of the boat.

What It Makes Possible

① Top up accessories from the boat

After tempering, cold water contracts the air in the hull — and in the seat, backrest, and foot brace too. The adapter lets you bring all of these back to pressure on the water, without pulling over to shore.

② Compatible AlpackaRaft accessories

Inflatable backrest
Inflatable seat
Inflatable foot brace
Pre-2016 top-off valves (2016 and earlier)

③ Compatible with third-party sleeping pads

The adapter also allows the Pack-A-Pump or AlpackaRaft inflation bag to work with most major-brand inflatable sleeping pads — Therm-a-Rest, Exped, REI. A useful crossover for paddlers who camp.

※ Compatibility with Japan-market sleeping pad valves is being verified on an ongoing basis. ※ Not compatible with Big Agnes accessories.

Storage

The adapter fits inside the Pack-A-Pump’s plunger handle — the built-in storage space. It stays with the pump and is ready when you need it.

Important Safety Note

Do not over-inflate.

The inflation tubes this adapter connects to — seat, floor, backrest, foot brace — are designed to be inflated by mouth or a low-pressure pump. The Pack-A-Pump generates significantly more pressure. Inflating too quickly or too much can cause these components to blow off.

Inflate slowly, in short strokes, and stop the moment the component reaches the right firmness.
