Best O- Ring seals now available online


O-rings are circular sealing elements with circular cross-sections and are mainly used in static applications. The sizes are specified by the inside diameter and the cross-section diameter. At, Horiaki, O-rings are manufactured according to metric and imperial international standards. All Standard Sizes and Compounds Custom Sizes and Specialty Compounds Boxed O-ring Kits. O-rings are one of the most common types of seals because they’re inexpensive, reliable and have simple mounting requirements. Since they are known as one of the most important elements of machine design, o-rings may be used in static applications, where little range of motion is required. O Ring Seals may be used in dynamic applications, like rotating pump shafts and hydraulic cylinder positions, also.

Moreover, we’re committed to providing the right product at the right price to every customer. Our technical sales team is experienced and knowledgeable about o-rings and their application. Because of this, we provide customers with guidance that ensures the optimal solution. We stock all major o-ring compounds.

How does an O-Ring seal work?                        

Seals prevent fluids from escaping through the gaps in mating pieces of hardware. The O-Ring sits in the middle of a gland when it’s at rest, but as pressure begins to rise in the sealing system, the O-Ring shifts to the opposite side of the pressure.

Because the material is soft, the O-Ring is mechanically squeezed to plug the hole between the two mating hardware pieces.

O-Rings - Industrial Applications

O-rings are predominantly used in places where different parts of a mechanism meet and where a chance of leakage is high. In technical terms, the meeting point is usually referred to as the mating surfaces and any gap found in this region is identified as the clearance gap. When O-rings are used, they will block these clearance gaps with o-rings and will ensure not even a single drop of the fluid passes through it in static applications.


While there are other methods to block this area including welding, soldering or brazing, those methods would not allow for an easy dis-assembly unit. The concept of using a soft material between two hard elements has been proven to be more efficient and reliable not to mention making a seal possible in a dynamic application where one of the contact services has motion. A machined groove will be found in the gland to which the ring is attached and the mating surface will be sealed.
