GORE™ Protective Vents allows EPS Core Surfboards to pass air back and forth between the core and the exterior of the board while preventing water from entering. This is due because EPS surfboard materials are affected by extreme temperature changes.

There is a double membrane of “Gore-Tex” either side of a rubber O-ring. This membrane is waterproof this allows the vent to works by allowing air and other gases to pass through the membrane freely but stops liquids from entering the enclosure.

The Gore-Tex membrane does not require any adjustment.

What is .... Gore Protective Vents for Surfboards and Watercraft?
 
Gore membrane vents allow the pass of air and other gases both ways while blocking the flow of liquid water.
The technology behind the vent's breathability lies in our ePTFE materials.  Gore microporous ePTFE membrane prevents pressure build up by constantly equalizing the difference in pressure between the inside of the enclosure and its immediate environment. This constant exchange reduces the pressure on the seals. The vent works by allowing air and other gases to pass through the membrane freely but stops liquids from entering the enclosure.  The  membrane offers varying flow rates and liquid protection.

The industry standard for epoxy Surfcraft that utilised expanded polystyrene foam or hollow boards such as timber surfboards.
