SAILTEC, Inc. has specialized in designing and building hydraulic tension and rig control for sailboats and custom marine hydraulics since 1983. Our cost effective and durable hydraulic solution, coupled with a serious dedication to customer service and product support has made SAILTEC the first production boat source for many top sailboat brands for over twenty years.
We manufacture hydraulic/pneumatic cylinders, hand pumps, and 12V & 24V electric pumps that operate to 5000 psi (350 bar) and can generate up to 100 ton of force. Our latest products include hydraulic control of hatches, transom doors, swim platforms, keel lifting, radar lifts and other specialized applications.
If this happens there are three variables that can cause it.
(1) External leak. By cleaning and tensioning your unit you will see, in time, oil leaking from some point.
(2) Internal leak. Usually after some time the seals can degrade and allow oil to leave the pressure system and return to the reservoir.
(3) Leaky valves.
In all three cases something is wrong. Whether it's been damaged or just wearing out, it is time for service.
