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

The O-Ring & Engineered Seals Division is now offering a rapid prototype program for solid and hollow spliced O-rings that will reduce lead times on small orders to improve sample and trial testing on enclosure projects. The program provides spliced rings available in a variety of cross sections and can be purchased in either solid or hollow profiles.
Spliced ring sizes
In the event that enclosure tolerances are large or the available compressive force is low, Parker engineers can design a custom hollow seal to help absorb large tolerances while providing very low compressive force compared to solid cord. Spliced rings with large inside diameters up to 95” are available in silicone and nitrile materials. Rings with inside diameters up to 57” are available in fluorocarbon. Cross sections of .070”, .103”, .139”, .210” .250” are regularly stocked and available to splice to the ring ID needed. The chart below outlines the current compounds, cross sections, and diameters available under the program.

O-Rings continue to be the most widely utilized sealing product. While the ‘Donut’ shaped profile has by and large been kept intact since their inception, continued elastomeric development has pushed o-ring temperature and chemical compatibility to limits unimaginable several decades ago.
Typically, O-Rings fail due to adverse effects of a number of factors, from improper installation and lubrication to incorrect size and design. The collection of videos below will help you minimize installation errors that may lead to failure (be sure to bookmark this page for future reference).

Hollow O-rings have long been used in enclosure applications and many other static applications.
Parker TechSeal Hollow O-rings can extrude, splice, and vulcanize extremely large o-rings that would be too costly to mold. Their dimensions can
