Stick-slip is a common phenomenon that can occur in seals due to uneven friction between objects sliding across each other.
This repetitive start-stop movement or vibration known as stick-slip can cause major issues and even failure of mechanical systems, including seals. However, proper seal design and knowing what to look for can help you avoid stick-slip in your machinery’s seals.
Here’s why stick-slip happens and how you can prevent this problem in your

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut elLubrication of O-rings is extremely important. The greatest benefit of using a lubricant is typically obtained during installation. Using a lubricant is going to decrease the surface friction of the O-ring helping to prevent abrasion, pinching or cutting of the O-ring during installation. Lubricating an O-ring can also help to seat the O-ring properly into the application, as well as aid and speed up automated assembly processes.

O-Rings are solid-rubber, doughnut-shaped seals used to block the passage of a gas or liquid when pressed between two mating surfaces.
They are amongst the most widely utilized seal designs in the world. Due to the number of ways they can be utilized, there are essentially an endless number of O-Ring sizes.
But despite the wide range of O-Ring sizes, every O-Ring has the same two dimensions: the inner diameter (ID), and the cross-section (CS). To attain

Low temperature stiffness isn’t something unique to aging. It’s a problem that has plagued seal designers for years, particularly with respect to aircraft fuel systems. Modern aircraft employ a complicated fuel system with multiple connections along the path from input through exhaust. Safety demands complete integrity of those connections at all times across the complete operating environment of the aircraft. Particularly challenging is maintaining an effective seal at extreme low temperatures.

HOW TO MEASURE AN O-RING | USING A CAPLIER | O-RING SIZING CONE
Our newest video release is something we tend to get asked somewhat frequently at Gallagher Fluid Seals. Despite it being a relatively easy subject, the question of "How do I find the size of my o-ring?" comes up more than you would think. We felt it made complete sense to do a quick video on the two most common methods to measure an O-Ring.
Measuring an O-Ring with a caliper
Measuring an O-Ring with a

Natural Rubber Short Supply
Plagued by global supply chain issues stemming from coronavirus and environmental issues, the natural rubber shortage continues to be exasperated by the war in Ukraine and Russia.
In 2021, shortages were reported mainly due to flooding and leaf disease. A poor crop led to a decrease in the cultivation of these highly desirable trees. The supply for raw gum already was expected to remain tight for several years due to the 7-year maturity period

Lubrication is an important, sometimes overlooked, component of sealing. Many applications require lubrication for installation to prevent seal damage and prevent injury during manual assembly. Internal lubricants reduce installation force and dynamic friction without the need for an external lubricant or coating. Internal lubrication also decreases break-out friction for dynamic applications. Operating seals with no lubrication can lead to heat buildup and accelerated wear that can result in leakage

In our continued effort to provide our customers convenient seal sizing guides, GFS is happy to present the newest technical bulletin.
- Parker 5-Dash Series Sizing Guide
Parker's 5-Dash series of o-rings are classified as commonly used o-rings sizes which do not fall in the AS568 line of o-rings and are also not true “metric” sizes.
