O-rings are a universal seal throughout the world. However, some axial applications may benefit from a different sealing solution called Press-in-Place seals, or PIP seals.
First, let’s define axial seal. “Axial” implies the seal is being compressed from top to bottom. In other words, the seal is pressed between two flat surfaces. One flat surface has a groove cut into it to retain the O-ring and limit compression. This may also be called a face seal.

A common question that comes from many customers is: “Can you tell me which O-ring compound meets this ASTM D2000 callout?” It’s understandable, since at first glance, the ASTM D2000 callout can be intimidating for determining the type of O-ring material. However, the ASTM D2000 is a very useful tool to quickly specify requirements for O-ring materials, and is standardized so it is easy to interpret industry wide. So, what is the ASTM D2000 specification, and how can I interpret it?
ASTM D2000 is a standardized description of rubber compounds. It was first developed for use in the automotive industry, however it is now used by many industries to specify requirements for rubber compounds in a consistent way. Think of the specification as a common language everyone in the rubber industry speaks, allowing us to communicate easily with each other without an interpreter. An ASTM D2000 callout

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.
Thermo-Chem™ firewall sheets, rope, tape, cloth and tubing are flexible, fire-resistant fabric products used in applications where flame and fuel resistance is required.
