With seals for pneumatic application uses, one consideration to think about is the severeness of the duty. Obviously, the durometer is very important. When you get into a 70, 80, or 90 durometer seal, it becomes very resistant to being smooshed. As the pressure increases—say 3,000, 4,000, 5,000, or maybe even 10,000 psi or more—it simply has a … [Read more...] about What makes a seal for hydraulics different than a seal for pneumatics?

Parker Hannifin unveils metal seal design for extreme temperatures
U.S. Patent No. 9,453,600, for a new stainless steel flat face sealing ring for use with tube fittings in extreme temperature applications, was recently issued to Parker Hannifin Corp. The new seal design was developed by engineers at the Parker Tube Fittings Division and is a principal design feature of the Parker Seal-Lok Xtreme line of flat face … [Read more...] about Parker Hannifin unveils metal seal design for extreme temperatures
How do you install a fluid power seal?
An important consideration for seals in fluid applications is installation—literally how a cylinder seal is installed, and what you need to know when you're picking a seal. How we describe a seal is the cross section, which is looking at a seal from the side. The cross section is the width across the U-cups, or from one side to the other. The depth … [Read more...] about How do you install a fluid power seal?
Why are the location of seals important in fluid power?
It matters where you put a seal. Every part of a cylinder has seals, and they're in there for a reason. The rod wiper is the one that is most exposed to the elements in any hydraulic cylinder application. It has a groove that pushes against the rod itself. Anytime the cylinder retracts, anything on the rod wants to be scraped off of it. You can … [Read more...] about Why are the location of seals important in fluid power?
What are some applications for seals in fluid power?
Seals are simple objects, but obviously very critical to fluid power applications. Without a seal, there would be no way to contain one, two, three or four psi, let alone 4,000, 5,000, 6,000 to 10,000 psi or more that you tend to experience in fluid power applications—and that's regardless of air, water, hydraulics, etc. They're the unrewarded … [Read more...] about What are some applications for seals in fluid power?

COG O-ring tool kit available
Professional O-ring tool kit is essentially first aid for technicians. Technical users know the problem all too well: Installing O-rings in cramped installation spaces without damaging them or the removal of stuck O-rings from grooves without causing damage to the machine is often a tedious and above all difficult affair. C. Otto Gehrckens now … [Read more...] about COG O-ring tool kit available
Is the oil and gas market ready to flip the switch on recovery?
At this week’s OTC (Offshore Technology Conference), the keyword was probably cautious optimism for the oil and gas market. The event—which has been down since its record-breaking year in 2014 as gas prices plummeted—continues to get smaller, but fluid power manufacturers and show organizers are still preparing for a slow and steady ramp-up. In … [Read more...] about Is the oil and gas market ready to flip the switch on recovery?
How do backup rings help to prevent O-ring migration?
Backup rings are used for both static and dynamic fluid power applications and prevent the migration or extrusion of an O-ring in the gap as pressurization and de-pressurization/pressure cycling occur. The profile shape of the backup rings is usually rectangular but may also be concave at the face mating with the O-ring. Manufactured in various … [Read more...] about How do backup rings help to prevent O-ring migration?
