The Boston valve was introduced October 2010 on our 2011 range. (2011 models: Catalyst, C4, Edge, Zephyr and Reo).
We have received feedback that some valves may leak. After further research our design team have found that one cavity on a valve plug tool was not molding a correctly formed thread.
This was only on a small batch of valves we were supplied. We have since informed our valve supplier of this discrepency and ensured that all valves will be molded correctly from now on. Our production team has also checked every valve in stock and removed the poorly formed valves.
As a safety precaution, your valve plug must be wrapped using PTFE plumber tape. Wrap the plug four times as shown in the PDF (link above). PTFE (Teflon Tape 0.075mm thick x 12mm) tape can be found in hardware stores.
This is a temporary solution until we replace this part for all customers. We will advise you as soon as this part is available with updates posted on http://www.flyozone.com/kitesurf/en/
The new male plug will be manufactured in red to distinguish it from the current black plug.
Ozone is committed to safety hence our decision to announce this safety notice due to a small percentage of defective valves from the supplier/manufacturer of the Boston valves.
Ozone wants all customers to be able to enjoy our products and would therefore like to apologise for any inconvenience.
Best regards
Team Ozone
