I use and sell HEPU from Germany.  Never ever seen a problem with them.  The one on my personal van has about 250,000 km on it and still doing fine.

             Please note that I will be away from my business travelling from December 02 until April 30, 2014.  Parts orders will be processed although not as quickly as usual.  I will always be available for contact by E-mail.  If you phone your call will be addressed by Joe Wallace here and he will either call you back or advise you to contact me directly by E-mail. Details of this adventure are on our Travel Blog: http://frankcondelli.com/travels/
