Wiper Seals Overview

Wiper seals are designed to deliver unmatched contamination exclusion in both hydraulic and pneumatic systems. With a focus on quality and performance, these seals are engineered to remove debris from rod and cylinder surfaces, ensuring the protection and longevity of your equipment. Their robust design is tailored to keep out environmental aggressors such as dirt, moisture, and other particles that can compromise the integrity and efficiency of machinery.

The primary role of wiper seals is to prevent the entrance of various contaminants such as dirt, dust, water, and other environmental elements that could impair the operation of cylinder assemblies. Wiper seals are essential in various applications, finding their place in construction equipment, mining machinery, agricultural tools, manufacturing devices, automotive systems, and aerospace components. By ensuring a clean rod surface, wiper seals maintain the system’s pressure, reduce the risks of leaks, and safeguard the performance of the entire sealing system.

To meet diverse industry demands, our wiper seals come in a selection of robust materials. Urethane showcases outstanding resistance to wear and tear, offering long service life in harsh conditions. Nitrile (Buna, NBR) provides excellent compatibility with petroleum-based oils and fuels, making it a versatile choice for various applications. Carboxylated Nitrile (XNBR) is selected for applications requiring higher abrasion resistance and toughness, particularly where wear resistance is of high importance. Finally, fluorocarbon (FKM) is renowned for its high-temperature resistance and its ability to withstand a broad array of chemicals, including oils, fuels, and hydraulic fluids. This makes it an excellent choice for environments where the seals are exposed to harsh chemicals or extreme temperatures.

Slotted Heel Wiper Seals

The slotted heel feature is designed to prevent pressure traps that can form between the rod seal and wiper in hydraulic systems. Pressure traps occur when high-pressure fluid becomes caught between the rod seal and the wiper, potentially leading to seal damage or failure and compromised system performance. The slotted heel allows fluid to bypass the wiper seal, equalizing pressure and preventing the fluid buildup that can lead to pressure traps.

This feature is crucial in applications where pressure spikes are frequent and unpredictable, ensuring consistent performance and seal integrity. By preventing pressure traps, the slotted heel protects against premature wear and contributes to the overall health of the hydraulic system. It allows for a smoother operation of the rod and seal, reducing the likelihood of malfunction or downtime due to seal-related issues. Whether incorporated into AN or ST profiles, the slotted heel enhancement is suitable for a wide range of applications, from heavy-duty machinery to precision equipment, where maintaining optimal pressure is essential.

Incorporating the slotted heel feature into your wiper seal selection ensures that your equipment benefits from advanced seal technology designed for longevity and reliability. It’s an essential consideration for any operation looking to optimize their hydraulic systems and mitigate maintenance concerns.

The AN style wiper seal is expertly designed to be compatible with MS-28776 (MS-33675) dash-size grooves. This low-profile seal is an industry standard for effective contaminant exclusion. Its shell, typically molded from high-grade urethane, is perfect for light to medium-duty hydraulic applications where durability and resilience are required. This style is particularly advantageous for systems that necessitate a compact seal without compromising on performance, ensuring that even the most restricted assemblies maintain their integrity and function.

Precision-molded from 90A durometer urethane, the ST style wiper ring is a robust contender for challenging rod wiping applications. Its flexibility allows for effortless installation into grooves and its toughness effectively handles the rigors of rod-wiping tasks. The ST style is a fit for light and medium-duty hydraulic and pneumatic systems and excels in large rod diameter settings. The snap-in design is deliberately oversized to ensure a snug fit, offering excellent stability and reliability. It’s an optimal choice for applications that demand a seal that is both easy to install and steadfast in operation.

The MCN Metal Clad Wiper Seal is characterized by its robust construction and thick inner lip that exemplifies its suitability for heavy-duty applications. Crafted from durable nitrile, this double-lipped seal is designed for enduring performance and enhanced wear resistance. Its metal shell is a mark of strength and contributes to the seal’s extended service life. The MCN seal is adept at keeping rods free from unwanted particulates and debris, playing a vital role in the protection and maintenance of machinery.

The MCU Metal Clad Wiper Seal is engineered for uncompromising durability in challenging environments, where resistance to wear is a critical factor. Constructed from urethane, this double-lip wiper seal is designed for longevity and consistent performance across various industrial applications. The metal cladding adds to the seal’s structural integrity and extends its operational lifespan, ensuring reliable functionality over extended periods. This seal excels in maintaining the cleanliness and efficiency of machinery by adeptly clearing particulates and debris, thus upholding the system’s integrity.
