ユニバーサルSUPポンプノズルハルキーロバーツ（HR）＆ボストンバルブアダプター

Ensuring precise Valve Compatibility(paddle board pump adapter) fitment is the primary defense against the air leaks that drive high warranty return rates. While the Halkey-Roberts standard is universal, manufacturing tolerances vary effectively between brands, often causing generic nozzles to fail under pressure. Ignoring these critical depth variations compromises the mechanical lock required to sustain 25 PSI, resulting in immediate equipment downtime.

This technical brief benchmarks the KelyLands Universal Nozzle Set against the strict 25 PSI airtight requirement. We analyze how interchangeable O-ring gaskets and specialized Boston Valve adapters bridge manufacturing gaps to ensure a secure, leak-proof connection for every unit in your inventory.

The Halkey-Roberts (HR) Standard: Why Is It the Gold Standard for SUPs?

The HR valve dominates because its twist-lock design mechanically secures high pressure up to 25 PSI. However, minor depth variations between brands require pumps with adaptable O-ring sets.

The Twist-Lock Mechanism and High-Pressure Capability

If you have ever tried to inflate a high-pressure rigid board with a friction-based valve (like a Boston or Pinch valve), you know the problem: the nozzle pops out the moment back-pressure builds. The Halkey-Roberts (HR) system solved this by becoming the “lock and key” of the SUP industry. It is not just about airflow; it is about mechanical security holding back 25 PSI.

• Mechanical Locking: The bayonet-style twist-lock secures the pump hose to the board. This prevents the nozzle from ejecting under the 12–25 PSI pressures required for rigid performance.
• Spring-Loaded Air Control: Unlike simple flap valves, the HR system uses a central pin. When depressed, it allows rapid deflation—critical for rolling stiff boards tightly for storage. When extended, it creates an airtight seal.
• Industry Standardization: Major players like Red Paddle Co and iRocker standardize on this valve. This creates a massive ecosystem of interchangeable aftermarket pumps and repair parts.

Handling Tolerance Variations: The Importance of Spare O-Rings

Here is the insider reality that most spec sheets ignore: “Standard” does not mean “Identical.” While the HR valve is the global standard, the internal pin depth and rim thickness vary slightly between factories. A nozzle that seals perfectly on a Red Paddle Co board might leak on a GILI Sports board because the fit is too loose, or it might not depress the pin at all if the fit is too tight.

KelyLands addresses these manufacturing tolerances directly in our pump kits. We do not just supply a single rigid nozzle; we provide a solution for the gap.

• Variable Depth Issues: If a board’s valve pin is shallower or deeper than average, a standard pump nozzle may fail to open the valve (causing the pump to read 0 PSI) or fail to seal (causing loud air leaks).
• The Universal Nozzle Set: Every KelyLands pump includes a set of spare O-rings (washers) with varied thicknesses. These allow the user to adjust the nozzle fit manually.
• Seamless B2B Integration: By including these spacers, we ensure your customers can achieve an airtight seal on virtually any brand of board without air leaking back out at the connection point.

Boston Valve vs. Pinch Valve: Can One Pump Service Your Kayak and Towables Too?

Yes. Our pumps utilize a standard 5-6 piece Universal Nozzle Set to handle both. The Stage 1 airflow (350L/min) fills large-volume items rapidly before pressure builds.

Valve Anatomy: Threaded Boston Designs vs. Flexible Pinch Valves

If you sell watersports gear, you know the frustration of incompatible valves. Boston Valves are the recreational standard for soft-structure boats and towables. They use a rigid, two-cap threaded system. You unscrew the top cap to inflate, allowing the internal check valve to hold air. To deflate, you unscrew the entire base, dumping air instantly. These handle moderate pressure better than basic toys but cannot withstand the 15+ PSI of a drop-stitch SUP.

Pinch Valves sit at the lower end of the spectrum. You find these flexible PVC nozzles on cheap pool floats and beach balls. They rely on a simple internal flap that stays closed until you physically squeeze the base of the valve. They are strictly for low-pressure, high-volume applications where structure rigidity is not a priority.

Universal Nozzle Set: Adapting the Pump for Non-SUP Gear

Many SUP pumps on the market ignore these auxiliary valves, forcing users to carry a separate foot pump for their kayaks. We solve this by including a 5-6 Piece Universal Nozzle Set as a standard accessory in every KelyLands box. This kit ensures the high-pressure hose connects securely to recreational gear, not just paddle boards.

• Boston Adapter: Threads directly into standard kayak valves for a hands-free seal.
• Pinch Adapter: A tapered nozzle that pushes the internal flap open for continuous airflow.
• Stage 1 Advantage: Our pump’s 350L/min low-pressure mode fills these voluminous items in seconds, far faster than manual pumping.

Gasket Thickness: How to Swap Washers to Fix Air Leaks at the Nozzle Connection?

Air leaks usually happen because different SUP brands use Halkey-Roberts valves with varying internal depths. Swapping the standard gasket for a thicker O-ring creates the necessary airtight seal.

Diagnosing Air Leaks: The Role of Valve Depth and Gasket Thickness

While the Halkey-Roberts (HR) valve is the global standard, the internal manufacturing tolerances differ significantly between board brands. A nozzle that fits perfectly on a Red Paddle Co board might be too loose on an iRocker model due to slight variations in valve depth. If the installed gasket is too thin, it fails to compress against the valve’s internal seal, leaving a gap where pressurized air escapes.

The issue can also go the other way. If the gasket is too thick, you physically cannot twist the nozzle into the locked position, or it might depress the valve pin prematurely, releasing air before you even start the pump. The first step in troubleshooting is confirming the leak originates from this connection point rather than the hose crimp or the board valve itself.

Installing Spare O-Rings: The KelyLands Universal Nozzle Set Solution

We solve this compatibility issue at the factory level. Every KelyLands pump includes a Universal Nozzle Set packaged with spare O-rings of varying thicknesses. This system eliminates the need for unprofessional makeshift fixes like wrapping the nozzle in plumber’s tape or using rubber bands.

• Remove the old washer: Use a small flathead or your fingernail to pry the existing rubber gasket out of the hose nozzle.
• Select a new thickness: Choose a slightly thicker O-ring from the provided spare kit to bridge the gap.
• Test the fit: Insert the nozzle into the board’s valve. It should twist and click into place firmly without requiring excessive force.
• Verify pressure: Once the High-Pressure Hose is locked, start the pump. The connection must remain airtight as the board reaches 20 PSI.

Kite Surf Mode: Does It Handle the High Volume Requirements of Kites?

Yes. Our dual-stage pumps initiate with a high-volume turbine (350L/min) to rapidly expand kite bladders before automatically switching to the compressor for final rigidity.

The Mechanics of Dual-Stage Inflation for Kites

Kites function differently than paddle boards during inflation. They require massive air displacement to take shape before any real pressure builds up. Using a single-stage high-pressure pump for a kite is inefficient because the piston mechanism moves too little air per cycle, making the process painfully slow.

Our system addresses this by treating Stage 1 as a dedicated “Kite Mode.” This stage bypasses the compressor and engages a turbine fan designed for rapid expansion. It floods the kite bladder with air to establish shape immediately. This automation eliminates the most exhausting part of the setup—the high-volume manual pumping phase—preventing user fatigue before they even hit the water.

Performance Spec: 350L/min Dual-Stage Technology

To handle the specific volume demands of kites, we engineered the KelyLands pump to deliver 350L/分 of airflow in the first stage. This high-velocity output fills large kites in minutes. The system relies on our Dual Stage Intelligent Switch, which monitors back-pressure. Once the pump detects resistance (indicating the bladder is expanded), it automatically engages Stage 2 (compressor mode) to finalize the pressure.

• 350L/min Airflow: Rapidly expands large volume bladders without delay.
• Active Cooling System: An internal cooling tunnel prevents the motor from overheating during prolonged high-volume runs, a common failure point in cheaper units.
• Universal Nozzle Set: Includes standard adapters to fit common kite valves alongside SUP interfaces.
