We are excited to present to you part 4 of our O-ring webinar series. For this portion, Benjamin Mell, GFS Application Engineer and Regional Sales Manager, will delve deeper into specific O-ring profiles. While a traditional O-ring has a circular profile, additional O-ring profiles and sub categories have evolved over the years to solve specific application challenges. We are going to review each of these profiles and their benefits.
Part 4 will discuss:
1. Standard O-rings
2. Cord-Rings
3. Quad Rings® / X-Rings
4. Encapsulated O-rings
5. Hollow O-rings
If you want to drastically improve the efficiency of your pump and reduce maintenance, the first thing to do is change your approach to maintaining your pump. Focus not just on the specialized equipment your plant uses, but focus on valves, pipes, and other crucial operational equipment.
Did you know that the most common source of wasted energy in pumping systems has to do with seals that weren’t properly sized for their applications? This causes throttling of the pump’s flow, and reduces efficiency. Pumps that operate in this manner also produce higher levels of vibration, which will cause unnecessary damage and reduce the longevity of the seals.
This blog will discuss the root causes of mechanical seal failure and how to extend the life of your mechanical seals.
The customer’s chemical treatment vessel has nonstandard rectangular flanges with a limited number of bolts. The limited bolting resulted in inadequate compression to seal the gasket and the non-standard shape made the use of a molded engineered gasket unfeasible. When tested, expanded PTFE leaked. There was no alternative known at that time so the mess of crystalized leaking media was accepted as normal.
Controlling friction using the properties of Teflon® and adjusting the durometer of an energizing elastomer allows us to adjust the load and control the force the seal applies.
Seals are often used as a barrier or exclusion device. When considering a device that becomes sterilized, seals often protect the internal components of that device.
Some systems require adjustment of the mechanism. Friction becomes a factor when making internal adjustments. An O-ring is always the easiest solution for sealing. But for fine adjustments, reducing the friction allows more control of the device.
A large wind turbine manufacturer continues to use Vesconite Hilube actuator bearing supports in its wind turbines’ hydraulic blade pitch control systems.
Pitch control systems are essential to protect wind turbines in adverse weather conditions as well as maximise the energy production of wind turbines. These systems allow blades to be twisted so that load can be reduced when wind speeds are high and even
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 common applications to consider throughout the design process.

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.
An important measure of hose flexibility is the Minimum Bend Radius (MBR). While most everyone understands that this is the smallest radius to which a hose can be bent, the method of measuring this radius is often misunderstood. Additionally, while most hose constructions list a single MBR, corrugated metal hose lists two: a static and a dynamic MBR. Let’s take a minute to review the differences between static and dynamic MBR’s and when they should (or should not) be used.
