Custom Engineered and Molded Seals

Custom Engineered and Molded Seals

MSP Seals, Inc. specializes in custom-engineered and molded seals designed to meet the needs of industries worldwide. While standard options can work for some applications, many projects demand higher precision, durability, and material compatibility than off-the-shelf products can provide. With decades of experience and a broad inventory of materials, MSP Seals delivers tailored sealing solutions that ensure performance, extend equipment life, and reduce downtime.

Sealing Solutions: Your Custom Engineered Seals Partner

When your application requires seals that go beyond standard specifications, MSP Seals is the partner you can trust. Every project comes with unique challenges, whether they involve unusual geometries, exposure to harsh environments, or compatibility with specialized fluids.

We manufacture a wide range of custom-engineered seals and related products, including:

  • Gaskets
  • O-rings
  • Back-up rings
  • Lathe cut seals
  • Boots
  • Bellows
  • Diaphragms
  • Grommets

Injection, Compression, and Transfer Molding Processes

Injection, Compression, and Transfer Molding Processes

MSP Seals uses three primary molding methods, selected based on part complexity, tolerance requirements, and production volume:

  • Injection molding. The most cost-effective option for producing small, intricate parts in high volumes. The process involves injecting heated material into a mold, allowing for fast, repeatable production of precise components.
  • Compression molding. Best suited for larger parts or applications with small to moderate volume needs. During the process, material is weighed, placed in a heated mold, and compressed under pressure to achieve the desired shape.
  • Transfer molding. Ideal for larger or complex parts requiring tight tolerances at higher production levels. In transfer molding, material is pre-heated in a chamber and then transferred into the mold cavity under pressure, balancing accuracy with production efficiency.

By leveraging the right molding process, we can deliver custom molded seals that meet both functional and cost requirements.

Custom Seal Materials, Applications, and Design Expertise

The strength of our custom-engineered seals lies in our extensive knowledge of materials and seal design. We offer sealing solutions in a wide range of materials to match the demands of each application:

  • Elastomers. Flexible materials valued for their sealing performance and ability to maintain elasticity under pressure. Examples of elastomers we work with include nitrile butadiene rubber (NBR, Buna-N), fluorocarbon, EPDM, fluorosilicone, silicone, neoprene/chloroprene, polyacrylate, and polyurethane rubber.
  • Metals. Including stainless steel, brass, and bronze, selected for strength, durability, and resistance to extreme conditions.
  • Specialized compounds. Options like PTFE (Teflon), nylon, ceramic, and carbon for unique performance properties such as low friction and chemical resistance.

From concept through production, we deliver seals that optimize performance and longevity for your equipment.
