What is the most common static seal?

rubber o-rings, sets of rubber o-rings in different sizes

Choosing the wrong seal might not be noticeable—until your system leaks, fails, or shuts down. That’s why many engineers and buyers ask: what’s the safest, most common static seal to start with? The most common static seal is the O-ring. It’s used in thousands of applications where two non-moving surfaces need to be sealed reliably […]

Is a lip seal static or dynamic?

A leaking shaft can destroy bearings and motors fast. Many customers ask if lip seals are dynamic or static—and getting this wrong leads to serious failures. A lip seal is a dynamic seal. It is designed to seal around a moving part, like a rotating shaft, to retain lubricant and block contaminants. Lip seal sealing […]

What is a static seal used for?

Rubber types for static sealing, showing EPDM, NBR, FKM, and silicone O-rings with labels for fluid, temperature, and chemical resistance.

Leaks don’t just waste resources—they destroy systems, one drop at a time. A static seal might look simple, but it’s often the only thing standing between a tight system and a costly mess. A static seal is used to prevent leakage between two non-moving parts. It’s commonly applied in flanges, casings, pipe joints, and covers […]

What is a static seal?

Silicone o-ring Industries

Sealing failure can lead to equipment damage, downtime, and profit loss. If your sealing solution doesn’t match your application, trouble is just a matter of time. A static seal is a non-moving seal used between two stationary parts to prevent fluid or gas leakage. It’s widely used in flanges, covers, and casings. Static seal example […]

What is the difference between PTFE and fluoroelastomer?

PTFE gasket vs fluoroelastomer seal comparison, showing rigid white plastic and flexible black rubber ring for sealing applications.

Both resist heat. Both resist chemicals. But only one stretches—and the other slides. If you’re choosing between PTFE and fluoroelastomer, understanding their strengths could save your system from premature failure. The key difference is that PTFE (polytetrafluoroethylene) is a rigid, non-elastomeric plastic with unmatched chemical resistance and low friction, while fluoroelastomer (FKM) is a flexible […]

What is fluoroelastomer rubber?

Fluoroelastomer seals for automotive, aerospace, and chemical use, including O-rings and gaskets, arranged by industry application

Not all rubbers are built for heat, fuel, or chemicals. If your seal fails near an engine or pump line, chances are you’re not using fluoroelastomer. Fluoroelastomer rubber is a high-performance synthetic rubber known for its excellent resistance to heat, oils, fuels, and aggressive chemicals. It’s commonly referred to by trade names like Viton®. Fluoroelastomer […]

Is fluoroelastomer rubber or plastic?

viton-o-rings-black-brown-red-green

It resists oil like plastic. It flexes like rubber. So is fluoroelastomer a rubber—or a plastic with rubbery behavior? Fluoroelastomer is a synthetic rubber, not a plastic. It belongs to a class of flexible, high-performance elastomers designed for sealing in harsh environments. Fluoroelastomer O-ring showing rubber-like flexibility I’ve had many clients ask this when comparing […]

What Is a Spliced Rubber Gasket?

Viton gaskets for chemical vent systems, multiple black rubber seals in concentric sizes, arranged on white background for high-temperature applications.

Standard gaskets don’t always fit large, irregular, or custom-designed equipment. So how do we seal those non-standard applications? That’s where spliced rubber gaskets come in. A spliced rubber gasket is a sealing gasket made by cutting lengths of extruded rubber material and then joining (or splicing) the ends together to form a continuous, closed-loop gasket. […]

What Is a Spliced O-Ring?

Spliced O-rings in EPDM, NBR, silicone, FKM, and neoprene materials, with two spliced samples shown below, color-coded and labeled on white background.

When standard O-rings can’t seal large diameters or irregular shapes, what’s the alternative? That’s where spliced O-rings come in. A spliced O-ring is a custom-sized seal made by cutting rubber cord to length and bonding the ends together to form a continuous loop. It’s ideal for large or non-standard groove applications. Spliced o-ring vs molded […]

Where are double lip seals used?

Double lip rubber seals in five sizes, black radial shaft seals with dual lips, labeled for gearbox, automotive, conveyor, and HVAC applications on white background.

One small leak can shut down a big system. In harsh, dirty, or high-pressure environments, a standard seal isn’t enough. That’s why double lip seals are the go-to choice for extra protection. Double lip seals are used in applications where both fluid leakage and external contamination must be controlled. They are common in pumps, gearboxes, […]
