O-RING/X-RING

DRI O-RING

Description

D-Rings are rings in the shape of a “D” that offer an alternative sealing solution to O-rings for use in rotary applications. They provide the same sealing properties as O-rings and can, in addition, be used in applications that experience high and low pressures, operating in a wide range of temperatures.

Application

Pharmaceutical Food industries

Materials

Nitrile Rubber (NBR) + Ethylene Propylene Diene Monomer Rubber (EPDM) + Fluorinated Rubber (FKM) + Silicone Rubber: Methyl Vinyl Polysiloxane (VMQ)

O-RING/X-RING

EPDM O-RING

Description

Ethylene propylene rubber is an elastomer prepared from ethylene and propylene monomers (ethylene propylene copolymer) and at times with an amount of a third (diene) monomer (ethylene propylene diene terpolymers).

Application

Brake systems Glycol-based fluids H20 steam

O-RING/X-RING

HNBR O-RING

Description

HNBR has been developed to meet higher temperatures than standard NBR while retaining resistance to petroleum based oils. Obtained by hydrogenating the nitrile copolymer, HNBR fills the gap left between NBR, EPDM and FKM elastomers where high temperature conditions require high tensile strength while maintaining excellent resistance to motor oils, sour gas, amine/oil mixtures, oxidized fuels, and lubricating oils.

Application

Water and steam up to 300 degrees Fahrenheit Fuel systems Oil resistant and high abrasion applications

Materials

Nitrile Rubber (NBR) + Ethylene Propylene Diene Monomer Rubber (EPDM) + Fluorinated Rubber (FKM)

O-RING/X-RING

LINER O-RING

O-RING/X-RING

NBR O-RING

Description

Nitrile rubber is the general term for acrylonitrile butadiene terpolymer. The acrylonitrile content of nitrile sealing compounds varies considerably (18% to 50%) and influences the physical properties of the finished material. The higher the acrylonitrile content, the better the resistance to oil and fuel. At the same time, elasticity and resistance to compression set is adversely affected. In view of these opposing realities, a compromise is often drawn, and a medium acrylonitrile content selected. Nitrile has good mechanical properties when compared with other elastomers and high wear resistance.

O-RING CORD

Description

O-ring cord is a rubber cord with a circular profile that can be cut to the required length. O-ring cord can be used as a static seal for when standard sizes are either unavailable or too costly.

ORI

Description

Iron Rubber is NOK’s brand name for a polyurethane elastomer. Iron Rubber was developed in 1960 as an elastic molding material that serves as a filler between a rubber region and a plastic region and has been improved again and again.

Application

Automobiles and construction machines

PTFE O-RING

Description

Polytetrafluoroethylene (PTFE) O-rings: Temperature & Chemical Resistant PTFE is a popular O-Ring material which is White in color. The PTFE O-Rings for use in applications which require a chemically resistant and non-compressible material. PTFE is the chemically inert of the O-ring materials. It is resistant to most chemicals including acids, bases, oils, steam and other chemicals. It is also very tough and abrasive resistant.

Application

Outdoors Lubricants Hydrocarbons Acids Alkalis Detergents Alcohol Ketones Steam Refrigerants

SILICON O-RING

Description

VMQ (Silicones) are a group of elastomeric materials made from silicone, oxygen, hydrogen, and carbon. Extreme temperature range and low temperature flexibility are characteristics of silicone compounds. As a group, silicones have poor tensile strength, tear resistance, and abrasion resistance. Special compounds have been developed with exceptional heat and compression set resistance. High strength compounds have also been made, but their strength does not compare to conventional rubber.

Application

General purpose Food contact Pharmaceutical
