Imperial O-ring set 

We offer O-ring sets designed for power hydraulics ( intended for contact with hydraulic oils ). Our offer includes imperial O-rings for various applications, such as O-rings for hose fittings ( hose ends ) or O-rings used in hydraulic connectors. The O-ring is placed in a special groove on the tip cone - ensuring a perfect seal of the connection on the cone. Imperial O-rings are thicker than metric O-rings and significantly thicker than ORFS O-rings. We offer all types of O-ring sets, including O-rings for specific machines, e.g., JCB, VOLVO, HITACHI etc. 

Imperial O-rings for power hydraulics

In power hydraulics, we have several types of threaded connections, including metric threads and metric O-rings designed for them, imperial threads and O-rings designed for them, ORFS threads and ORFS O-rings designed for them. 

What are imperial O-ring sets?

Imperial O-ring sets are practical sealing kits used in various technical systems, including power hydraulics, pneumatics, and other mechanical devices. O-rings are essential for ensuring connection tightness, preventing leaks and pressure loss in systems. Products offered by Hydron are characterized by high quality and durability. The sets include O-rings made from wear-resistant materials such as NBR, FKM (Viton), or EPDM, providing excellent sealing properties. The sets are available in various sizes, allowing you to choose the right O-ring for a specific application. Each set has been carefully designed to contain a wide range of imperial sizes, facilitating repairs, maintenance, and assembly. This eliminates the need to purchase individual components separately.

Where are O-rings used?

O-ring sets are used in many industries and applications, such as: Power hydraulics – sealing cylinders, fittings, and valves. Pneumatics – seals in compressors, pressure regulators, and control systems. Automotive – used in engines, cooling, and braking systems. Machine industry – sealing various devices and tools.

Imperial O-ring sets – a complete set of seals for imperial installations

Imperial O-ring sets are a practical solution for service centers and workshops working with installations based on the imperial standard. One box contains imperial O-rings in many sizes, enabling quick selection of the appropriate seal without having to interrupt work. Such sets are particularly useful for servicing imported machines, hydraulic and pneumatic installations, and systems using imperial threads. Imperial seals are commonly used in power hydraulics, especially in systems where hydraulic fittings with an imperial thread, hydraulic hoses and machine components from the American and British markets are used. A properly selected imperial O-ring ensures connection tightness, protecting the system from hydraulic oil leaks and operating pressure drops.

A practical box with imperial O-rings for the workshop and service center

Imperial O-ring sets are packed in a solid box with compartments, which allows for easy segregation of individual sizes. This form of storage significantly improves work in the workshop and in the mobile service center dealing with hydraulic hose repair, assembly of imperial connectors and the maintenance of high-pressure hydraulic systems. The box makes it easy to keep order and quickly access the required seal.

Imperial O-ring sets in hydraulic and pneumatic connections

Imperial O-ring sets are used in both power hydraulics and pneumatics. They are used for sealing threaded connections in hydraulic valves, directional control valves, hydraulic pumps and components interacting with high-pressure hydraulic hoses. In pneumatics, imperial O-rings are ideal for compressed air installations and auxiliary systems. Imperial O-ring sets are often used in construction, agricultural, and industrial machinery service centers. They prove effective during the repair of imported machines, hydraulic power units, and devices where imperial threads and standards are applied. Imperial O-rings enable quick repairs of components such as imperial hydraulic connectors, hydraulic plugs, tees, and elbows.

Why it is worth having an imperial rubber seal set always at hand

Imperial seals in one box help avoid downtime and speed up repairs. A wide range of sizes allows the seal to be matched to many types of connections, which increases work efficiency and reduces the risk of leaks in hydraulic and pneumatic systems.
