Hydraulic Seals For Every Job

At Mac’s, we understand that every hydraulic system is unique.  That’s why we carry a diverse inventory of hydraulic seals. From small-scale applications to heavy-duty machinery, we have the perfect fit for you. Some of our available options include:


Wipers, also known as scrapers or dust seals, serve as protective components in hydraulic systems, preventing contaminants from entering the system and ensuring smooth operation. They scrape off dirt, debris, and moisture from the piston rod, extending the life of the system and improving overall performance.


U-seals, also known as U-cups, are versatile sealing devices commonly used in hydraulic and pneumatic applications. Their U-shaped cross-section provides effective sealing action, preventing fluid leakage in both static and dynamic applications. They offer easy installation, high flexibility, and resistance to a wide range of fluids and pressures.


O-Rings are simple but highly effective sealing elements used in various industries. They are circular rings made of elastomeric materials, providing reliable sealing in static and dynamic applications. O-Rings offer excellent resistance to compression, chemicals, and temperature variations, making them suitable for a wide range of sealing requirements.

Backup Ring

Backup rings work with O-rings or other sealing elements to provide additional support and prevent extrusion or damage under high pressures. They are typically placed on the non-pressure side of the seal to enhance its sealing capabilities and extend its service life.

Piston Seals

Piston seals are essential components in hydraulic and pneumatic systems. They ensure a tight seal between the piston and cylinder bore, preventing fluid leakage and maintaining system efficiency. Piston seals are available in various designs, including lip seals, compact seals, and composite seals, each tailored for specific operating conditions.

Wear Bands

Wear bands, also known as guide rings or bearing strips, are used to guide and support pistons or rods in hydraulic and pneumatic cylinders. They provide a low-friction surface, reducing metal-to-metal contact which minimizes wear and extends the life of the component.

Snap Rings

These circular fasteners fit into grooves on shafts or inside bores to secure components axially. They provide a simple and efficient method for retaining parts like bearings or seals in assemblies, ensuring their proper positioning and preventing unintended movement.


Lockwires, also known as safety wires, are used to secure fasteners, seals, or other components that are prone to loosening or vibration-induced movement. They are typically twisted around fasteners in a specific pattern to create a mechanical lock, providing an added level of safety and preventing unintentional disassembly or tampering. Lockwires are commonly used in critical applications where secure connections are vital.


Choose From Durable, Quality Brands

We carry multiple brands, such as SPX Bolting and Enerpac with strong reputations for delivering high-quality, durable, and dependable products. 

Hydraulic Hoses and Fittings

Our available selection of hydraulic hoses includes hoses with up to 10,000 PSI from our suppliers, in sizes ranging from ¼” all the way up to 1 and 1 ¼”.

We have in-house hydraulic hoses, built to withstand pressures up to 5000 PSI. Crafted with precision and utilizing premium materials, our hoses provide exceptional durability and reliability.

We also offer a wide range of accessories and fittings for your hydraulic system. Some of our available selection includes:


National Pipe Thread, commonly called “NPT,” is a standard tapered thread used in pipe fittings. It ensures a secure and leak-resistant connection between pipes and fittings. NPT creates a mechanical interference that forms a tight seal, making it ideal for plumbing, hydraulic systems and pneumatic systems.

O-Ring boss

O-Ring Boss (“ORB” for short) provides versatility in fluid systems. ORB is highly valued for its ability to provide strong, leak-free connections in hydraulic systems with the ability to withstand high pressures.

JIC Fittings

JIC (Joint Industry Council) fittings are widely used in fluid systems. They offer a reliable connection for high-pressure applications. They feature a 37-degree flare seat, which provides a metal-to-metal seal, ensuring leak-free performance. JIC fittings are known for their ease of assembly, making them suitable for hydraulic and pneumatic systems. We stock JIC in ¼ - 1 ¼.

O-Ring Face Adaptor Fittings

O-Ring Face Adaptor fittings are designed to provide a secure and leak-resistant connection in hydraulic systems. They feature a flat face with an O-ring groove that creates a positive seal. These fittings offer easy installation and removal, making them suitable for applications requiring high reliability and fluid compatibility.
