Types of Hydraulic Seals
Hydraulic and pneumatic seals are designed based on factors like working temperature, cylinder speed, operating pressure, application, and the medium used.
Typically, these Automotive Lift Repair Tampa Florida seals are non-metallic, soft rings housed or arranged in combinations to form a sealing unit, preventing fluid leaks in applications involving reciprocating motion. They are essential in machinery, facilitating the conversion of liquid into linear motion.
Hydraulic seals are crafted from materials such as rubber, PTFE, and polyurethane. The choice of material depends on the specific medium or constraints, including pressure, fluid type, temperature, and chemical compatibility. For guidance, visit our Fluid Compatibility Tool at AlleghenyYork.com.
– Static Hydraulic Seals: These seals are positioned in non-moving housings, sealing within their confined space.
– Dynamic Hydraulic Seals: Rod and piston seals fall under this category. Rod seals handle movement along the rod’s inner diameter, while piston seals operate along the outer diameter of the cylinder bore.
Piston Seals
Piston seals ensure that liquids or other media do not bypass the piston, as system pressure moves it through the cylinder. They come in single-acting (pressure acts on one side) and double-acting (pressure acts on both sides) varieties.
Rod Seals
Automotive Lift Repair Tampa Florida Rod seals are the most critical component in the cylinder sealing system. They prevent internal fluid from leaking out as the rod moves back and forth. Together with wiper seals, they protect the hydraulic system from external contaminants like dust and dirt.
Wiper Seals
Also known as Automotive Lift Repair Tampa Florida scraper seals, wiper seals are typically used with other sealing elements. They maintain a tight fit while allowing a reciprocating rod to move through the inner seal bore.
Wear Rings
Wear rings keep the piston centered, ensuring even wear and pressure distribution on the seals. Both rod and piston setups utilize wear rings.
Our range of hydraulic and pneumatic seals supports a wide variety of operating conditions. Common applications include cylinders, hydraulic presses, forming machines, and mobile systems.
We offer seals for single- and double-acting cylinders, composite piston seals, compact seals, independent wear rings, bonded seals, static seals (O-rings), and symmetrical seals. Our products feature ultra-low friction, broad temperature tolerance, water resistance, and exceptional durability.
1. Identify Your Seal Profile
Start by examining the cross-section of the seal and comparing it to a seal profile chart. You can download our seal profile catalog [here]().
2. Measure the Seal’s Dimensions
Determine the Outer Diameter (OD), Inner Diameter (ID), width, and height of the seal. These dimensions are often printed on the seal, but if they aren’t, you can measure them with a ruler, vernier calipers, or calipers. Be sure to take multiple diameter measurements around the seal to obtain an average.
3. Measuring Multi-Part Seals
For multi-part seals, measure the OD, ID, and width of each component.
4. Measuring Bearing Rings
When measuring bearing rings, ensure you also include the gap in your measurements.
5. Measuring O-Rings
To measure O-rings, use a ruler, calipers, or verniers to determine the section size. Always measure from the internal sides of the O-ring. Alternatively, you can use a measuring cone for accuracy. All measurements can be cross-referenced with an O-ring chart, which you can request from us.
6. Ordering Replacement Seals
Having accurate measurements will simplify the process of ordering replacement seals. If you have any questions or need assistance, our knowledgeable team is always available to help.
Types of Automotive Lift Repair Tampa Florida Hydraulic Seals
Hydraulic and pneumatic seals are designed based on factors such as working temperature, cylinder speed, operating pressure, application, and the medium involved.
These seals are typically made of non-metallic, soft materials and are either housed individually or arranged in combinations to form a sealing unit. Their primary function is to separate or block fluids in applications involving reciprocating motion. Hydraulic seals play a vital role in machinery, facilitating the conversion of liquid into linear motion.
Hydraulic seals are commonly made from a variety of materials, including rubber, PTFE, and polyurethane. The compatibility of these materials is determined by the specific operating medium, as well as pressure, fluid type, temperature, and chemical compatibility.

– Static Hydraulic Seals: These seals are fixed in a housing where there is no motion, sealing only within a confined space.
– Dynamic Hydraulic Seals: This category includes rod seals and piston seals. Rod seals interact with the inner diameter of the rod or shaft of a hydraulic cylinder, while piston seals function along the outer diameter of the cylinder bore.
Piston Seals
Piston seals prevent liquids or other media from leaking around the piston as system pressure pushes it through the cylinder. They can be single-acting (pressure acting on one side) or double-acting (pressure acting on both sides).
Rod Seals
Rod seals are a critical component of a cylinder’s sealing system. They prevent internal fluids from leaking out during the rod’s back-and-forth motion.
Wiper Seals
Also known as scraper seals, wiper seals are typically used alongside other sealing components. They provide a tight seal while allowing a reciprocating rod to move through the inner seal bore.
Wear Rings
Wear rings help keep the piston centered, ensuring even wear and proper stress distribution on the seals. They are used in both rod and piston applications.
Our range of Automotive Lift Repair Tampa Florida hydraulic and pneumatic seals accommodates a wide variety of operating cycles, with common applications including cylinders, forming machines, hydraulic presses, and mobile cylinders.
We offer seals for both single- and double-acting cylinders, composite piston seals, compact seals, independent wear rings, bonded seals, static seals (O-rings), and symmetrical seals. Our products feature ultra-low friction, a wide temperature range, water resistance, and extended lifespan.
Hydraulic cylinders are essential components in the hydraulic systems of modern heavy equipment, including excavators, skid steers, and tractors.
These cylinders utilize the principles of fluid mechanics to convert hydrostatic pressure into linear force, powering the machinery and its attachments.
Typically, Automotive Lift Repair Tampa Florida hydraulic cylinders are filled with hydraulic fluid or oil. Inside the cylinder, a piston connected to a piston rod moves back and forth as fluid is pumped in and out on either side of the piston. This movement causes the rod to extend and retract, enabling the motion of arms, attachments, and other mechanical systems on the equipment.
