Protect Your Seal Aftermarket with Part Identification Technologies
Parker is revolutionizing part identification technology with a multitude of options. Customers are able to benefit from various identification methods such as non-permanent and permanent part markings by selecting their part number and company logo on the seal. For more advanced identification, a customer may opt to use the Parker Tracking System or utilize our RFID seals for tracking purposes. These identification methods ensure product authenticity and reduce seal installation errors by providing visual indicators for the assembly process.
Basic part marking – non-permanent identification
Non-permanent markings are applied to the surface of the seal and can be in the form of a company logo, unique part number, barcode, or other seal information. Non-permanent markings ensure Parker’s part origin, enables part level traceability and provides an easily visible cue to operators. This value-added feature helps reduce installation errors in addition to protecting customers against counterfeit seals.

Poppet Seals for Demand Flow Regulators
Avoid Leakage and Support a More Accurate System
Poppet seals are sealing elements used to control fluid or gas flow in various applications. They consist of a movable component, the "poppet," that fits snugly against a valve seat to stop or allow fluid to pass through. When the poppet lifts, it opens the flow path, and when it returns to its seat, it creates a seal, stopping the flow.
There are many applications in industrial

Conductive Seals from Parker Hannifin
When unprotected electrical currents flow through the bearings, the currents can cause issues such as arcing, pitting, fluting, and frosting, damaging the bearings and degrading the reliability and longevity of your motor. These stray currents lead to issues such as noise, vibration, higher temperatures, and ultimately, premature failure. Traditional solutions include shaft grounding blocks, carbon fiber grounding rings, and ceramic insulated bearings.
