Construction equipment works in tough environments full of dust, dirt, and chemicals. Without reliable seals, contaminants can get inside and cause equipment issues such as corrosion and malfunctions. This can lead to costly downtime for maintenance or repairs.

Finding the right construction equipment seals for every application is easier with MSP Seals. Our team can supply seals for different equipment and environments, so you can enjoy optimal performance. Learn more about commonly used construction equipment seals and materials below.

Common Types of Construction Equipment Seals

Quality seals create a barrier that blocks outside contaminants without impeding the functionality of moving parts, manual controls, or electrical connections. At MSP Seals, we can supply common construction equipment seal types such as:

O-Rings

O-rings from MSP Seals are a popular sealing choice, with a circular shape to fit snugly between two adjacent circular surfaces. These rings can help prevent air or fluid leakage, leading to reduced downtime.

Lip Seals

Also known as radial seals and oil/grease seals, MSP’s lip seal products fit snugly around moving parts such as rotating shafts or axles. Thanks to their high elasticity, lip seals can withstand high friction and wear.

Gaskets

Our gasket products are made from compressible materials like rubber, cork, or soft metals. These sit between two mating surfaces (such as a bolt and a metal enclosure) to keep air and moisture out.

Mechanical Seals

MSP’s mechanical seals are spring-loaded to maximize sealing pressure in high-temperature and high-pressure rotating sub-assemblies, such as those found in pumps and compressors. They have a rotating face and a stationary face that sit perpendicular to the rotating shaft.

Packings

Packings from MSP Seals provide a simple but effective sealing solution. The circular inserts or ropes wind around a shaft to fill the empty space between the shaft and housing, reducing the risk of leakage.

Factors to Consider When Choosing Seals for Construction Equipment

At MSP Seals, we offer a wide selection of standard and custom construction seals to meet specific operating environments and withstand varying pressure levels. Whether you need a seal for a hydraulic system, one with sufficient elasticity for long-term use, or a seal with a special design to accommodate constant motion, we can help you find the right option for your construction equipment. There are several key factors to assess when selecting or designing a seal for your construction equipment:

  • Seal installation. We carry seals that can be replaced without fully shutting down operations, minimizing interruptions and associated costs.
  • Operating environment. We can supply sealing options for applications involving environmental hazards, such as continual submersion or exposure to dust and debris.
  • Temperature and pressure. Certain seal types, such as graphite gaskets, can withstand the temperatures and pressures of the given environment and mating surfaces.
  • Exposure to chemicals and contaminants. Consider sealing options that can resist harmful or damaging substances without degrading. For example, our nitrile seals can withstand exposure to fuels and oils.
  • Durability and resistance. While some tougher or high-resistance materials may have a higher initial cost, they may also reduce repairs or operational disruption in the long run.
  • Seal design and compatibility. Factors to consider include whether mating surfaces are static or dynamic (thus requiring specialized designs that can accommodate motion).
  • Lubrication. Some materials are self-lubricating, while others may require regular applications of lubricant to minimize friction and wear.

Common Seal Materials

A wide range of materials are available to meet the unique demands of your construction application, including plastics, elastomers, and metals, as well as different composites.

Elastomers

Our elastomer seals can return to their original shape after being compressed, creating an airtight seal. Our elastomer options include:

  • Nitrile/Buna Rubber (NBR)
  • Fluorocarbon Rubber (FKM)
  • Silicone Rubber
  • EPDM

Plastics

Plastic seals from MSP Seals are adaptable and cost-effective while reliably preventing leakage. Customers can choose from the following:

  • Polytetrafluoroethylene
  • Polyurethane
  • Polyamide

Metals

MSP’s metal seals provide a high degree of strength when used in construction equipment. We offer metal options such as:

  • Carbon steel
  • Stainless steel
  • Bronze

Composites

MSP has several high-performance composite materials to choose from, including:

  • Graphite
  • Teflon-graphite
  • Metal-reinforced elastomers
