SVI International offers Zero Leak Technology (ZLT), engineered to help owners of in-ground vehicle lifts. SVI's new ZLT sealing systems are designed using seal material that is abrasion-resistant to withstand road salt, dirt, rust scale and debris found in the difficult shop environment. Unlike outdated seal materials, ZLT seals are not affected by ozone or ultraviolet light and have an unlimited shelf life. The seals are custom-made for the lift's low pressure application. The seal stays in constant with the rod surface to maximize performance and eliminate oil loss and associated costs.
