The Valve-Stem Seal is a finely engineered complex combination of sealing and controlled metering. Meeting the performance needs takes a combination of correct materials, metering rates, lip design, lip tolerances, concentricity, vacuum and or pressure controls, along with any specific customer requirements.
Tobar, Inc, and our supplier/partner have developed equipment for “in house testing”. Thus, for seals we supply we are capable of testing to general requirements and to our customer’s specifications.
If you are an OEM manufacture Tobar can help you with initial development, prototype samples, and production requirements. In the aftermarket area we have hundreds of currently tooled items we can supply, or tool specifically to your needs.
