An O-ring is a torus shaped mechanical seal gasket.It is a circular cross-section elastomer ring that is meant to be installed in slots and compressed when fitted between two or more components to establish a seal at the interface.

O-rings are commonly employed in static or dynamic applications where there is relative motion between the pieces and the O-ring. Fluid or gas seals are examples of static applications while Pump shafts and hydraulic cylinder pistons are examples of dynamic applications. Because they are inexpensive, easy to fabricate, reliable, and have simple mounting requirements, O-rings are one of the most utilized seals in machine design. Typically, O-rings are made of NBR, HNBR, EPDM, FFKM, PTFE, and other materials.
Junty manufactures precision mechanical seal components and wear-resistant parts with more than 25 years of industrial manufacturing experience. This product page at product / o-rings covers seal rings, bushings, bearings, rotary unions, and four core engineered material families: silicon carbide, tungsten carbide, carbon graphite, and advanced ceramics.
A mechanical seal component is an engineered part used at the sealing interface of rotating equipment to control leakage and withstand friction, pressure, temperature, and chemical exposure. Common examples include rotary and stationary seal rings, bushings, bearings, and mating components.
Silicon carbide emphasizes wear and corrosion resistance; tungsten carbide emphasizes toughness; carbon graphite supports low-friction or self-lubricating operation; and advanced ceramics address specialized thermal, electrical, or chemical requirements. Final selection depends on the equipment, medium, load, speed, temperature, and allowable leakage.
