Two things are equally important for the reliable performance of an O-Ring seal: the right size and the right material. Parker’s O-Ring Selector is an engineering tool that enables users to make the right material and size selections easily, quickly and reliably – in a single application. The accuracy of the results ensures the desired performance of the O-Ring in the subsequent application. This is primarily based on the fact that both functionalities – the material selection and the O-Ring size calculation – are closely interlinked. This achieves a new quality in calculating the total sealing system.
Overview of the O-Ring Selector
The Parker O-Ring Selector is divided into three main sections:
- Service Conditions & Material Selector
- Size Selector
- Notes
The Service Conditions & Material Selector section is focused on mapping the material-related application conditions. Entering the operating temperature range, the desired polymer family and/or material hardness will take the user to the suitable material selection. The Advanced Material Selector enables experienced users to specify the operating conditions in even greater detail. Here the medium to be sealed can be selected from a database containing 2,500 media. In addition, a search for required approvals and conformities can be run.

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.

Custom Environmental Seal Solutions: When Unique Requirements Throw a Curveball
When it comes to the topic of utilizing elastomeric seals, it’s stereotypical to consider environmental sealing as one of the simpler categories of applications. Near-ambient pressure and temperature conditions and a lack of exotic or aggressive chemistries are the kinds of details that typically come to mind. However, throw in a curveball

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
