Due to its excellent resistance to petroleum products, and its ability to be compounded for service over a temperature range of -35°C to +120°C (-30°F to +250°F), Nitrile /NBR is the most widely used elastomer in the seal industry today. Also many military rubber specifications for fuel and oil resistant O-rings require nitrile based compounds.
O-rings can do that too if you cut the groove properly. The point of all of them when you are sealing is to make up for unevenness in the metal parts that are going together. My experience is that o-rings will take up much more unevenness than the other approaches, but they are more expensive to incorporate because they need a groove to sit in.

*Determine the fitting type - male o-ring, o-ring, male insert o-ring, male flare, or flare using the illustrations on the following pages. *Match the fitting with the illustrations to determine fitting size. The fitting dimension is determined by measuring the O.D. of the tubing directly behind the nut.
O-rings ; USP Class VI. USP stands for U.S. Pharmacopeia, a private (non-government) organization that "promotes the public health by establishing state-of-the-art standards to ensure the quality of medicines and other health care technologies". For plastics, they have six different classes based on duration and application.

Technical Handbook O-rings In designing an O-ring seal, it is important to determine the O-ring compound early, as the compound selected may have an influence on the gland design. The application determines the rubber compound, the primary factor being the fluid to be sealed. But the elastomer must also resist extrusion when exposed to the maximum

O-Ring Colors. Over time and in certain industries, specific o-ring colors have been used to differentiate between materials. Below are a variety of o-ring colors and the most common materials associated with each color. **Disclaimer: It is never safe to assume an o …
The designation, or definition, of an O-Ring consists in identifying and expressing its two fundamental dimensions: internal diameter and cross-section of cord (or thickness). In practical use, with large O-Rings, the development of the diameter is also used, specifying the length of the circumference. It is very important to consider the size ...
Now back to the ring on the finger. Nowadays, when a person wears a ring on their right-hand ring finger, it means that he wants to dress up his appearance a bit and that's the only place his favorite ring fits. Besides, his only other alternative may have been the left-hand ring finger, which (as you know) is reserved for the wedding band.
3 O-Ring Basics Seal Thinking™ Elastomer seals are unlike any other materials that design engineers confront. Metal or plastic parts, for instance, are probably failing if visibly distorted. But, an O-ring MUST be deformed to function properly. In fact, an O-ring that is not squeezed and stretched in its application is the wrong O-ring ...

O-Rings are available in almost all durometers, with 70 or 90 durometer, the most common in most compounds. Softer sealing materials, with lower hardness readings, will more easily flow into the microfine grooves and imperfections of the mating parts, but softer compounds, like 50 durometer compounds, wear and extrude very quickly.
O-Ring Groove Design Overview. Global O-Ring and Seal has developed o-ring groove design and gland dimension guidelines. These are intended for use in basic design consideration and to understand the core principles involved in o-ring gland/groove design. Numerous factors go into the appropriate design of a gland/groove including but not ...
So, enter the o-ring seal. These new o-ring caliper kits are supposed to help stop the leaking and the introduction of air. I suppose the idea is that the o-ring is more robust compared to the lip seal. There was no piston pull-back in the original design so it's not expected in this o-ring modification. There is still a spring pushing the ...

nominal cross section O-Rings. Until now, O-Ring standards have left a gap between the 1/8" and 3/16" nominal cross sections. In de-signing this new group of O-Rings, we left spacing in the part numbers to allow us to add additional sizes should they be required. Please contact us if you are looking for a size not shown in the 5/32' group.
