The Elastoguard family of seals is engineered to outperform the demanding standards required across various industries, delivering impeccable sealing capabilities whether the equipment is operational or stationary. In applications where only one direction of action is involved, Elastoguard seals distinguish themselves by increasing contact pressure against high-pressure zones and tapering it off towards areas of lower pressure. This adept control over pressure disparities greatly diminishes the chance of fluids adhering to adjacent surfaces during separation. Moreover, it facilitates the smooth reabsorption of any residual fluid on the rod back into the system as the rod retracts.
Indeed, Elastoguard’s innovative design stands out for its effectiveness, tailored to go beyond the rigorous expectations of varied industrial settings. It promises no leaks during activity and maintains a solid seal when stationary. The Elastoguard also offers reduced friction to decrease energy loss, superior resistance to wear for a longer lifespan, and an uncomplicated installation process even in tight spaces.
Crafted from various PTFE materials known for their outstanding resistance to wear and friction, Elastoguard Seals exhibit a wide operational capability. These materials are compatible with a variety of hydraulic fluids and can perform over a large temperature range. This versatility makes them ideal for numerous applications, from mobile hydraulics and machine tools to challenging conditions like those found in the oil and gas industry’s downhole operations.
