HEYTUR Inflatable Boat SUP Pump Adaptor Standard Schrader Conventional Air Pump Air Valve Adapter Spoke Plate Attachment(Black)

• The HEYTUR inflatable stand up board valve adapter will allow you to connect any standard electric pump, foot pump or compressor to the schrader valve fitting, the standard valve for car and bicycle tires.
• It works on the majority of inflatable stand up boards. It is also suitable for boats and kayaks which also use the Halkey-Roberts valve for inflation.Use your compressor or tire pump to easily reach 20 PSI.Be very careful not to over inflate your board or craft, and check the board's pressure frequently.
• This is an adaptor only. The speed at which your board inflates will depend on the pump used.Because the compressors/tire pumps take time to inflate, it is recommended to inflate the board by hand hand pump until it becomes difficult to pump, and then use the adaptor to top off the pressure.
• Remove your SUP valve cap and ensure that the valve is sealed for inflation by rotating the central pin into the outer/closed position.Insert the valve adapter into the SUP valve the same way as you would insert the pump hose nozzle. Connect any standard schrader pump to the valve adapter fitting to inflate your board. Monitor board pressure frequently while inflating!

The car tire inflator is a low-volume high pressure pump, (10Litre/min up to 100PSI) but these SUP pumps are high-volume low-pressure ， It takes about 15 minutes to fill up with acar tire inflator It fits the standard Halkey Roberts (HR) valve, which most SUP have, but some cheaper SUP don't have a HR valve, so beware. When used with a car tire inflator, it definitely does work, but the cheapest inflators will be too slow, and you probably need an inflator that outputs at least 70 Litres/minute (2.5GPM).
