UH05 / U641 hydraulic seals with heat-resistant urethane material are designed for cylinder sealing and operate in extreme temperature ranges for long service life under severe and extended operation (e.g., construction equipment). UHO5 seals are ......More

Dual seal flange adapters improve the reliability and safety of high-vibration, high-shock hydraulic four-bolt connections in critical subsea oil and gas applications. They are an alternative to traditional SAE Code 62 flanges. They are available in ......More

A novel hydraulic seal minimizes friction and leakage across a wide pressure range....More

Today’s hydraulic cylinders move larger loads, faster, and over longer distances. Here’s how it affects the seals....More

A discussion group has been formed to work towards improved specification for hydraulic piston rod surface texture. A meeting, led by Bob Flitney, a UK consultant in seal R&D and surface texture, was held in Stuttgart, Germany in October and attended ......More

In mobile and stationary hydraulic applications, rod seals are exposed to high pressure and friction for extended periods. To achieve a long service life seals must be wear- and extrusion-resistant, compatible to aggressive media, have a wide operating ......More

Like sunscreen and sunburn, sealing and leakage will always be intertwined. If you misunderstand proper sealing practices, don't expect that maintaining your system will be a day at the beach....More

The Octi-ring was specifically designed to combat the effects of the high-speed small strokes that a standard issue O-ring is incapable of handling. We generally assume that a moving part will wear out faster than one that ......More

Koenig Expander sealing plugs meet TS16949 standard, offering “zero defect” sealing for hydraulic and pneumatic applications. They are available in metric and inch sizes, in carbon and stainless steel. Most styles are RoHS compliant. Blow-out ......More

By Joachim Mschel and Thomas Papatheodorou Parker Hannifin Corp. New formulations of thermoplastic polyurethanes (TPUs) hold promise to boost sealing performance in a variety of applications — not just the most demanding. The need ......More

Large-diameter, spring-loaded seals are designed for challenging applications. Outer and inner shell is made of mild steel. Spring retainer is stainless steel and sealing lip is held in place with garter spring of galvanized steel. They perform in ......More
