Part 3 - Basics of O-Rings - Core Applications
A static seal is one that remains stationary. And in a truly static seal, the mating gland parts are not subject to relative movement. Most O-ring applications are static.
But what happens when there is relative motion? That's where dynamic seals enter. In this new video webinar, Ben Mell, Regional Sales Manager at Gallagher will discuss reciprocating seals, rotary seals, o-ring design, and

Elastomers are a high molecular weight polymer that exhibits little plastic flow, and has a rapid recovery from an extending or compressing force. Elastomers are produced naturally as gum rubber on commercial rubber plantations or manufactured synthetically. Today, more than 32 synthetic rubbers are known.
In Part 2 of our webinar series, Benjamin Mell, Regional Sales Manager at Gallagher Fluid Seals will elaborate on the most common types of elastomers used in o-ring applications. He

O-rings are the most common sealing product in the world. An O-ring is a versatile solution that will effectively seal every time, assuming that basic design parameters are followed. It is also an inexpensive sealing solution compared to other products. An O-ring should always be considered for a seal application due to its low price and availability.
This blog and is the first in a multi-part video webinar series on the basics of o-rings.

So, you’ve unboxed the shiny new Parker seals you ordered – now what? Installing seals for the first time can be challenging without the right know-how and tools. In this article we’ll discuss best practices for seal installation in linear fluid power systems, and how to design your system to make seal installation fast and damage-free.
SEAL GROOVE STYLES
First, let’s look at three common groove styles:
• Closed
• Stepped, and
• Open (or two-piece)Closed groove
The closed seal groove fully encapsulates the seal and is the most common style used (see Figure 1).
Closed grooves are simple to machine and offer the best support for seals. Since seals in this configuration are surrounded by solid metal, without a well-developed process, installation can be challenging. Rod seals need to be folded to fit into internal (throat) grooves and piston seals must be stretched over the outside of the piston.
Notice how both designs shown in Fig. 2 and Fig. 3 utilize static seals (turquoise colored seal) on the opposing side of the dynamic, primary seals. Therefore, installation in either instance requires techniques and tools for both rod and piston seals.
Stepped groove
Typically utilized to ease seal installation, stepped grooves feature a reduced diameter on the low-pressure side of the seal as shown in Fig. 4 and Fig. 5.
As shown, the “step” is just wide enough to hold the seal in place as the rod or piston strokes back and forth. This way, seals don’t have to be folded or stretched nearly as much when installing. This design works well for single seals only holding pressure from one direction, like Parker FlexiSeals™.
When using multiple seals stacked in series or in systems with bi-directional pressure, a closed or two-piece groove is needed for support on both sides.
Open and two-piece grooves
Open or two-piece grooves are used when the seal is either too small to be stretched or folded into a closed groove, or if it’s made of a material that doesn’t spring back after flexing.
Figures 6 and 7 show two examples of open grooves. Figure 6 uses a washer and a snap ring to hold the seal in place. Figure 7 uses a bolt-on cap. These groove designs can be used for bi-directional seals, too. As you can see, open grooves cost more to produce but seal installation is a snap.
Open grooves also make removing the seal much easier – useful in systems which require periodic seal replacement.

Rubber seals are used in numerous industries to prevent the unwanted leakage of liquids and gases in various components such as pumps, valves, pipe fittings, and vacuum seals, to name only a few. However, all seals are not created equally. Rubber seal design consists of several elements to ensure that the seal delivers optimal performance in the given environment.
One of the most common types of industrial rubber seals, the O-ring, relies on mechanical compressive deformation to act as a barrier

Sealing can often be a frustrating challenge when dealing with batteries and battery storage solutions. Determining what materials are compatible with certain chemistries or developing a profile that provides optimal sealing under available compression can be a time-consuming task for those outside the sealing industry. A trial and error approach can have a significant overall cost impact through multiple prototype iterations, prolonged testing, and ultimately, delaying product commercialization.
Specialized support
With Gallagher Fluid Seals and Parker Sealing's design and material engineers, we can provide support to your team in the critical, early stages of product development.
