My door operates correctly except when opening and closing and while open air is rushing from the cylinder pictured. I understand this is the locking cylinder. Air is rushing from around the rod in this cylinder when rod is extended     Is anyone familiar with a repair kit for the pictured cylinder. Seals, wiper etc. I suppose I can remove cylinder and repair. Also I read a mention of someone calling Bode for advice. I need that contact information. The cylinder is Masat cylinder are parts available from them?
Leaking cylinder is in picture on right side
