Frequently Asked Questions

MSP Seals supplies a wide range of sealing products, including O-rings, hydraulic seals, shaft seals, pneumatic seals, oil seals, gaskets, and specialty sealing components. We also offer custom-engineered seals designed to meet unique dimensions, materials, and performance requirements across many industries.

Unfortunately, no. We don’t typically supply seals for vintage or classic automotive applications. Due to tooling requirements, it’s often not economical to make a single seal for these situations.

No, we do not currently offer online ordering. To place an order, please contact our sales team directly by phone at 317-866-5000 or email sales@mspseals.com so we can ensure you get the correct product for your application.

Yes. We have a walk-in location open Monday through Friday, 9:00 a.m. – 4:00 p.m. At our store, we can:

• Measure seals and help identify replacements
• Provide technical support and product guidance
• Fabricate custom hydraulic hoses while you wait

We recommend emailing us in advance with details, as our counter can experience long wait times. View on Maps.

Yes. MSP Seals can accommodate both short-run orders for maintenance or prototyping and full production-run quantities for ongoing programs.

Yes. We can provide PPAP documentation and support when required for your seal needs. Our team works closely with customers to meet quality and compliance standards specific to the seal application.

We supply a wide range of seals designed for many applications:

• Hydraulic & Pneumatic Seals: Rod seals, piston seals, wipers, and wear rings
• Rotary Seals: Oil seals, mechanical face seals, and custom rotary solutions
• Static Seals: O-rings, gaskets, and backup rings
• Custom Thermoplastic & Elastomer Seals: Designed and manufactured to meet unique specifications

If you’re unsure which type of seal you need, our team can help identify the right solution for your application.

We work with a broad range of materials to meet different sealing and application requirements, including:

• Elastomers: Nitrile (Buna-N), FKM, EPDM, Silicone, Neoprene, FFKM, HNBR and others
• Thermoplastics: PTFE, UHMW, PEEK, Nylon, Acetal, TPV, and custom blends
• Rubber Compounds: Standard and specialty grades for chemical, temperature, and wear resistance
• Graphite, Felt, and Other Specialty Materials: For high-temperature or unique sealing environments

Our team can recommend the best material based on your application’s pressure, temperature, chemical compatibility, and wear conditions.

Custom-engineered seals from MSP Seals are designed to fit exact specifications, ensuring optimal performance, longer service life, and reduced downtime compared to off-the-shelf seals. By tailoring the material, geometry, and tolerances to your application, custom seals can improve efficiency and lower maintenance costs.

Yes. MSP Seals offers prototyping services for new sealing designs, allowing customers to test and refine products before full-scale production. This service shortens development timelines and ensures seals perform as expected.

Hydraulic seals are designed for systems that use pressurized liquids, such as hydraulic cylinders, and must withstand high pressures and fluid compatibility demands. Pneumatic seals, on the other hand, are built for systems using compressed air or gas and typically operate at lower pressures but higher speeds. MSP Seals provides both types to match your equipment’s needs.

For high-temperature environments, materials like Viton^® (FKM), silicone, and perfluoroelastomers (FFKM) offer excellent heat resistance and long-term sealing reliability. MSP Seals can recommend and supply the best compound based on your temperature, chemical, and pressure requirements.

PTFE seals offer superior chemical resistance and low friction compared to most rubber seals, making them ideal for aggressive fluids and harsh operating conditions. Rubber seals, however, often provide better flexibility and sealing at lower costs. MSP Seals can help determine which material is best for your application.

Common causes include improper material selection, incorrect installation, contamination of fluids, excessive pressure or temperature, and wear over time. MSP Seals helps customers avoid these issues by providing expert material guidance, precision manufacturing, and quality assurance.

Yes. MSP Seals manufactures and supplies oil seals specifically designed for high-pressure and demanding applications. These seals can be customized for material, lip design, and size to ensure leak-free performance.

MSP Seals serves industries such as automotive, heavy equipment, agriculture, oil and gas, rail and locomotive, food and beverage, and industrial manufacturing. Each industry benefits from seals engineered to handle its specific pressures, temperatures, and regulatory requirements.

Seals in agricultural equipment protect components like hydraulic cylinders, pumps, and gearboxes from contamination, prevent fluid leaks, and ensure reliable performance in harsh outdoor environments. MSP Seals provides rugged, long-lasting sealing solutions tailored to farm machinery.

FDA-compliant seals ensure that materials contacting food meet strict safety and hygiene standards. MSP Seals supplies FDA-approved materials and designs for food and beverage processing equipment to help manufacturers maintain compliance and prevent contamination.

In automotive and heavy equipment, durable materials like NBR, Viton^®, PTFE, and polyurethane are commonly used for O-rings, oil seals, and hydraulic seals. MSP Seals can recommend the optimal sealing solution based on load, temperature, and fluid exposure.

For oil and gas, MSP Seals provides high-performance seals capable of withstanding extreme pressures, corrosive fluids, and wide temperature ranges. Options include PTFE and elastomeric compounds, metal-cased seals, and custom designs built for safety and reliability in critical environments.

MSP Seals maintains strict quality assurance standards and holds certifications such as ISO 9001:2015 to ensure consistent manufacturing quality and compliance with industry requirements.
