Hydraulic motor seals are critical components that prevent fluid leakage, retain pressure, and protect rotating assemblies from contamination. McNeil Industries supplies precision hydraulic motor seals engineered for specific OEM platforms, with a focused product line serving Permco motors and a select Parker Hannifin pump application. Our inventory includes 15 dedicated part numbers covering shaft lip seals and related components used in hydraulic motors and pumps. These products are manufactured to meet dimensional and material requirements for dependable field performance in hydraulic equipment.
OEM-Focused Hydraulic Equipment Seals
McNeil Industries concentrates its hydraulic motor and pump seal offerings on Permco applications. With one exception for a Parker Hannifin pump, our hydraulic equipment seals align directly with Permco motor and pump configurations. This focused approach allows us to provide accurate fit, consistent material quality, and dependable sealing performance for replacement and maintenance needs.
If you service Permco motors, you can source the correct hydraulic motor seals from a single, reliable supplier. We maintain part number clarity and application alignment, helping you reduce downtime and avoid cross-reference confusion.
Our hydraulic motor seal line includes:
- Shaft lip seals for rotating assemblies
- Housing gaskets for secure sealing between components
- O-ring and IP seal configurations for static sealing points
- Supporting seal components matched to OEM requirements
Each part is aligned with specific Permco series and pump/motor builds, allowing you to order with confidence.

Lip Seals for Hydraulic Motor Applications
Lip seals are a core component in hydraulic motor sealing. These radial shaft seals are built to contain pressurized hydraulic fluid while preventing contaminants from entering the motor housing. McNeil Industries supplies lip seal part numbers configured for Permco motors, including double lip styles that provide added sealing contact.
Housing gaskets are also available for sealing motor housings and pump assemblies. These gaskets provide a secure interface between components and are matched to the intended application.
If you need confirmation on compatibility, our team can assist with part number verification based on your motor or pump model.
O-Ring, IP Seal, and Quad Ring Options
In addition to shaft lip seals, McNeil Industries provides supporting sealing elements such as ip seal, o ring, and quad ring configurations. These components are used in static and light dynamic sealing positions within hydraulic motors and related hydraulic equipment seals assemblies.
O-rings and IP seals are commonly used to seal mating surfaces, end caps, and housing sections. They are available in material options compatible with hydraulic fluids and temperature requirements.
Quad ring designs offer a four-lobed profile that increases sealing contact compared to standard O-rings. This design helps maintain stability in grooves and can reduce twisting during installation. For applications that require improved sealing reliability within hydraulic cylinder seals or motor assemblies, quad rings provide an effective solution.
Spring Energized Seals for Demanding Conditions
For applications requiring higher pressure capability or enhanced sealing force, McNeil Industries can provide spring energized seals. These seals apply mechanical energy through an internal spring element to maintain consistent sealing contact.
Spring energized seals are suitable for:
- High-pressure hydraulic pump applications
- Rotating or reciprocating motion requiring consistent contact force
- Situations where elastomer-only seals may lose preload over time
If your hydraulic motor or pump application demands higher performance sealing, we can review your requirements and identify the appropriate configuration.
Hydraulic Motor Seals vs. Hydraulic Cylinder Seals
Hydraulic motor seals are primarily used in rotating assemblies, sealing around drive shafts and housing interfaces. Hydraulic cylinder seals, by contrast, are typically used in reciprocating motion applications. While the motion differs, components such as o-ring, ip seal, quad ring, and certain spring energized seals may appear in both systems, depending on design.
McNeil Industries focuses this product line on hydraulic motor seals and hydraulic pump applications.
