How to use a pump adaptor?

To use a SUP pump adapter, thread the adapter's hose-side fitting onto your pump hose, select the correct O-ring thickness for an airtight seal, then press and twist the valve-side nozzle into the board's Halkey-Roberts valve until it locks — this creates a sealed connection so the pump can pressurize the board without air escaping.

The Tuomico HR valve adapter connects to the pump hose on one end (0.55" inner-threaded fitting) and to the board's Halkey-Roberts valve on the other (0.8" valve-side diameter). Getting the O-ring thickness right is the most important step — the kit includes 3mm, 5mm, and 6mm options. Start with the 5mm O-ring; if you hear air escaping around the valve, switch to the 6mm. Once sealed, run the pump to your target PSI and twist the adapter out of the HR valve to disconnect.

• Tuomico HR valve adapter hose-side diameter: 0.55" inner-threaded, for standard electric SUP pump hoses.
• Tuomico HR valve adapter valve-side diameter: 0.8", sized for Halkey-Roberts valves used by iRocker, Red Paddle Co, and GILI Sports.
• Included O-ring thicknesses: 3mm, 5mm, and 6mm — start with 5mm and size up if air escapes.
• Recommended inflation target: 12–20 PSI for most inflatable SUPs; the HT-768C reaches 25 PSI maximum.
• Inflation time with a correctly sealed adapter: approximately 4 minutes from flat to 15 PSI on a standard 10'x6" (300L) board using the HT-768C.
