Some early-release Niphean NP-PRO Series paddle boards were shipped with an additional inflation valve in place of the pressure gauge. Your paddle board remains fully functional. A replacement gauge will be shipped to you free of charge.  

Why Was the Gauge Not Installed? 

During final inspections, a batch of pressure gauges did not pass Niphean’s strict quality control testing. To ensure shipping timelines, we temporarily installed a second inflation valve in the location reserved for the pressure gauge.

🔧 How to Replace the Valve with a Pressure Gauge 

Part 1: Removing the Air Valve

1. Prepare an octagonal wrench and an electronic air pressure gauge.
2. Inflate the paddleboard to 3 psi.
3. Open the rear air valve knob.
4. Insert the octagonal wrench.Use your other hand to press down on the top of the wrench.Turn counterclockwise to loosen the valve base.
5. While deflating the board,press down firmly around the valve with both hands,until the area collapses and the valve base reaches the bottom.
6. Use one hand to hold the valve base firmly in place to prevent movement,while unscrewing the valve base to remove the valve.

Note:Do not release your hand from the valve base area.Keep it pressed in place until the pressure gauge is fully installed.

Part 2: Installing the Air Pressure Gauge

1. Take the electronic air pressure gauge.Insert the threaded end into the valve hole and screw it in steadily until snug.
2. When hand-tightening is no longer possible,use the octagonal wrench to turn clockwise and secure it.
3. Open the front air valve.Insert the air pump hose.Inflate to 3 psi until the board begins to bulge.Use the wrench to gently tighten once more.The installation is now complete.

Part 3: Test the replacement results

1.  Prepare soapy water and stir or shake until foam appears.
2. Sprinkle the soapy water with foam around the electronic air pressure valve until it covers the surrounding seams.
3. Check whether there are bubbles coming out from the electronic air pressure valve.
4. If bubbles are generated, it may be that the electronic air pressure valve is not tightened. You can continue to tighten it with an octagonal wrench.
5. After the test, wipe off the soapy water with a soft cloth or rinse with clean water.
