Sealing decisions are often left until the end of product development. By the time an email is sent to Gallagher Fluid Seals, the gland may already be fixed. This may not pose a problem in many applications, but it can often leave the seal engineer with few options. Having input from the seal expert in the early stages will allow for greater flexibility in choosing a seal and better chances at optimal sealing.
Measuring an O-Ring is quite simple when you have the right tools at your disposal. All that is required is a clean, level surface; an o-ring; and a measuring device such as a caliper or other measuring tools such as cones, gauges, and size charts.
To measure an O-Ring, following the directions below:

Dimensionally specifying an o-ring can typically be done with just

Two things are equally important for the reliable performance of an O-Ring seal: the right size and the right material. Parker’s new 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.
The Parker O-Ring Selector is divided into three main sections:
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.
