LEASH PLUG, SELF-REGULATING VENT AND HOUSING

We’ve been using these woven teflon vents in our custom boards for years now. Installed properly, they let air pass through, but not water, allowing air pressure in the board to equalize with the atmosphere.

Vents are manufactured to a high standard by Donaldson Filtration Solutions here in the USA. Installation can vary from board to board and it’s up to each builder to work out their own installation. The housing is installed into the board much like traditional screw-in vent housing. The difference is, when installing the vent you need to use a 16mm socket instead of a screwdriver.  Once in place they are strong and safe. Donaldson suggests that these are lifetime vents, never needing replacing. We do recommend keeping them clear of wax and sand and rinsing them from time to time with fresh water.

Warning- These vents are fragile before they are installed and are a little trickier to install than the screw-in variety. Use care and caution when installing and be sure the socket you use is fully engaged on the vent and that the o-ring on the vent is compressed onto the housing.
