Seals are small components that have an enormous effect on equipment operation. In many industries, these products mean the difference between safe, reliable performance and catastrophic failure. With that in mind, finding a reliable sourcing partner that provides quality solutions is essential.
As a globally leading seal supplier, MSP Seals offers an extensive selection of high-performance sealing products for OEM and MRO needs, including O-rings, rotary shaft seals, hydraulic seals, pneumatic seals, and custom seals. We can develop and optimize sealing solutions to meet unique design requirements and ensure dependable performance in demanding environments. Below, you can learn more about our product offerings and their uses in different applications.
Types of Seals at MSP Seals
At MSP Seals, we offer a wide array of sealing products designed to meet even the most demanding industry needs.
O-Rings
An O-ring is a circular sealing product made from flexible, yet durable materials. It is installed within a small groove between two hardware components during assembly where it compresses between the mating surfaces. This creates a tight seal that prevents unwanted contaminants from entering an assembly while keeping system fluids from leaking through.
Our O-rings are suitable for both moving and stationary systems. Some of their most common applications include:
Electronic Equipment
Electronic Equipment
Many types of connectors and switches use O-rings to keep moisture and dust from getting inside.
- Hydraulics and Pneumatics
Hydraulics and Pneumatics
Heavy-duty equipment features many moving parts that cannot be assembled without O-rings. Pistons, actuators, and cylinders are just a few common applications.
- Food and Beverage Processing
Food and beverage processing
O-rings maintain hygienic conditions inside processing plants by preventing equipment leaks and contamination.
- Plumbing
Plumbing
Many plumbing components require O-rings to form a tight seal, including faucet components, valves, pipes, and more.
- Medical devices
Medical devices
Respiratory equipment, fluid transfer devices, pumps, and drug delivery devices all rely on O-rings to achieve a leak-proof seal.
O-rings from MSP Seals come in a variety of materials to suit the demands of diverse installation sites. Whether your application involves high temperatures, corrosive chemicals, or other environmental challenges, we can help you source the ideal material to achieve lasting performance. Common options include:
- EPDM
- Nitrile Butadiene Rubber (Buna, NBR)
- Fluorocarbon (FKM)
- Silicone
- Polyurethane
- PTFE
- Neoprene
Hydraulic Seals
Hydraulic seals are flexible, circular rings that are manufactured with a groove along their surface to help them fit securely into hydraulic components. Each seal is carefully crafted to fit snugly within specific hydraulic cylinder parts. After installation, they prevent fluids from escaping, keeping them reliably sealed within the appropriate chambers.
These products must be durable, flexible, and compatible with high-temperature environments. Rubber and polyurethane are popular materials for these products since they resist cracking and provide lasting durability. However, we offer a wide range of other options depending on the chemicals your application involves, pressure levels, temperature requirements, and other factors. Material selection is crucial since hydraulic seals must withstand piston movements and increasing fluid pressure.
The hydraulic seals we offer are used in a diverse range of applications, including:
- Automotive
Automotive
Hydraulic seals create a barrier that prevents liquids like oil, hydraulic fluid, and coolant from leaking.
- Manufacturing
Manufacturing
Hydraulic seals protect internal components from contaminants like dirt, dust, and moisture.
- Power Transmission
Power transmission
Hydraulic seals help maintain system pressure and prevent fluid leakage in power transmission systems, resulting in reduced downtime.
- Oil Refineries
Oil refineries
Hydraulic seals are critical for components such as pumps, valves, and cylinders that must handle high-pressure fluids during the refining process.
Pneumatic Seals
In pneumatic systems, tightly sealing internal components are essential to keep machinery operational. Quality pneumatic seals from MSP Seals prevent system pressure loss and contamination, allowing heavy-duty equipment to function reliably. Our pneumatic seals are flexible components designed to tightly connect valves and pneumatic cylinders. They not only prevent gas from escaping pneumatic systems but also ensure foreign materials like dust do not enter the system.
Pneumatic seals are used for both rotary and reciprocation motion. For reciprocating motion, double-acting pneumatic seals accommodate both directions of movement, while single-acting options are used for only one axial direction. No matter what industry you’re in, our team can help you source the ideal product for your needs.
Our pneumatic seals come in many materials to ensure compatibility with virtually any cleaning agent or operational media your application involves. The most common materials include:
- Nitrile (NBR/Buna)
- Polyurethane
- Fluorocarbon Rubber (FKM)
- Silicone
- EPDM
- PTFE
Rotary Shaft Seals
Also referred to as a radial shaft seal, a rotary shaft seal is a flexible yet durable product designed to form a tight barrier along a rotating shaft. These components keep contamination out of industrial equipment, vehicles, and other types of machinery while simultaneously ensuring lubricants or other fluids remain inside the system.
Rotary shaft seals are essential for equipment that uses oil to protect mechanical components. We offer many types of rotary shaft seals, including braided packaging, V-ring seals, mechanical seals, and more.
The most common applications for our products include:
- Automotive
Automotive
Rotary shaft seals are used in wheel bearings, engine crankshafts, differential gears, and other automotive components.
- Food and Beverage
Food and beverage
These seals maintain stringent hygiene standards by preventing contamination due to machinery oil leaks.
- Marine Applications
Marine applications
Propeller shafts, thrusters, and rudder shafts all require durable seals to prevent seawater ingress.
- Motors
Motors
Rotary shaft seals keep coolant and lubricant from leaking out.
Custom Seals
Many sealing applications require a precision fit or unique performance capabilities. If your project could benefit from a custom-engineered solution, our team is here to help. We bring decades of experience to seal design and can help you troubleshoot a problem or optimize a product for improved performance, manufacturability, chemical resistance, and much more. We offer PPAP and can meet your just-in-time delivery requirements.
