O Rings

Nitrile O Rings
Get Latest Price
Nitrile butadiene rubber (NBR) is a family of unsaturated copolymers of 2-propenenitrile and various butadienemonomers (1,2-butadiene and 1,3-butadiene).The properties vary depending on the ACN content which ranges between 18% and 50%.
The more nitrile within the polymer, the higher the resistance to oils but the lower the flexibility of the material.NBR has the ability to withstand a range of temperatures from -30 °C to +135 °C.
Applications:
It is used in the automotive and aeronautical industry to make fuel and oil handling hoses, seals, and grommets. It is also used to create moulded goods, adhesives and sealants.

Silicon O Rings
Get Latest Price
Silicon O Ring is generally non-reactive, stable, and resistant to extreme environments and temperatures while still maintaining its useful properties. The material is also very sensitive to fatigue from cyclic loading. It is a highly inert material and does not react with most chemicals.
Silicone has the ability to withstand a range of temperatures from -60 °C to +200 °C.
Applications:
High temperature fuel injection ports can use silicone o-rings.

Rubber O Rings
Get Latest Price
O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, reliable, and have simple mounting requirements.
Applications:
The O-ring may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons.

Polyurethane O Rings
Get Latest Price
Excellent wear resistance and high tensile strength. Polyurethane O Ring has the ability to withstand a range of temperatures from -30°C to 90°C.
Applications:
Polyurethane O Rings are used in the manufacture of microcellular foam seals and gaskets; durable elastomeric wheels and tires; automotive suspension bushings; electrical potting compounds; high performance adhesives; surface coatings and surface sealants; and hard-plastic parts (i.e., for electronic instruments). Good for Drive Belts.

O Ring Seal
Get Latest Price
Brand | na |
Properties:
O-rings function as compact and reliable sealing devices by absorbing the tolerance stack-up between closely mated surfaces in both dynamic (moving) and static (stationary) applications.
The o-ring seals by blocking any potential leak path of a fluid (gas or liquid) between two closely spaced surfaces. The o-ring is generally installed in a machined groove in one of the surfaces to be sealed. As the two surfaces are brought together, forming a gland, they squeeze the cross section of the o-ring.
The common materials of O Ring Seal(Mechanical Seals) include: Fluoroelastomer (FKM), perfluoro rubber (FFKM), nitrile rubber (NBR), Viton coated PTFE double, double PTFE coated Fluoroelastomer, flexible graphite
Temp Range: -20°C to 200°C

Quad Rings
Get Latest Price
Quad rings can be used both static and dynamic sealing applications. The four-lobed design provides twice the sealing of a standard O-ring, but requires less squeeze to maintain an effective seal. This reduction in squeeze means less friction and improved seal life, and because parting lines are between the lobes, away from the sealing surface.
Applications:
Normally used in applications where pressure is 2500 PSI or higher.

Dynamic Seal
Get Latest Price
Dynamic seal retains or separates fluids, also keeps out contaminants, and contains pressure. It creates a barrier between moving and stationary surfaces.Dynamic seals are either contact or clearance. Contact seals bear against the mating surface under positive pressure. Clearance seals operate with positive clearance, therefore no rubbing contac.
Applications:
- Military/Defense/Homeland Security
- Aircraft / Aerospace
- Chemical Processing
- Electronics
- Medical
- Semiconductor
- Telecommunications
- Industrial
- Filtration
- Power / Alternative Energy
