O Rings

O-Ring (FKM)

Description

An FKM O-ring designed as a cost effective alternative to Viton®. It is typically used where resistance to high temperatures, chemicals and oils is required.

Application

FKM has good ozone resistance, excellent resistance to mineral oils and greases, and has outstanding temperature resistance. It can be used as an alternative to Nitrile (NBR) at higher temperatures and in outdoor sealing applications.

O-Ring (EPDM)

Description

EPDM O-rings are manufactured from a blend of EPDM and other polymers. They are typically used as an O-ring for general purpose applications.

Application

EPDM has good resistance to water, and some weathering and ozone resistance. It is not suitable for contact with petroleum liquids. The material is designed for medium range applications.

O-Ring Nitrile 90

Description

Nitrile 90 O-rings are manufactured from a combination butadiene and acrylonitrile. They are typically used as a cost effective O-ring for higher pressure applications.

Application

Nitrile 90 O-rings have some resistance to oils, greases and other petroleum based products. They is not suitable for contact with aromatic hydrocarbons. They provide good compression set, tear, and abrasion resistance.

O-Ring Silicone

Description

Silicone O-Rings are commonly used within food, beverage and pharmaceutical applications. They have one of the widest temperature range of any O-ring material.

Application

Silicone O-Rings have excellent heat and flame resistance together with very good ageing and weathering characteristics. They have relatively poor tear resistance so should be used in static applications

Bonded Washers

Description

Our Bonded Seals consist of a rubber sealing element that is bonded to the inner wall of a metal washer. They are used in applications where high pressures demand greater sealing capacity that can be obtained with copper washers. Available in a range of materials dependant on the application, in both metric and imperial sizes.

Application

Also known as Dowty seals, bonded seals and washers provide reliable and dependable resistance in high pressure applications. They are particularly suited to sealing under the heads of bolts and threaded components, for Pipe Couplings and a wide range of connector applications where a perfect face-to-face contact is required for sealing gases, oils, and other fluids.

Hydraulic Seals

Description

Hydraulic seals are generally relatively soft, non-metallic rings captured in groove or fixed in a combination of rings, forming a seal assembly, to block or separate fluid in reciprocating motion applications. They can be made from a variety of materials such as polyurethane, rubber or PTFE. The type of material is determined by the specific operating conditions.

Application

Hydraulic seals are designed to suit the cylinder working pressure, speed, operating temperature and fluid. Static hydraulic seals are located in a groove and see no movement; dynamic hydraulic seals are exposed to movement of the shaft or bore of a hydraulic cylinder. Common types include Piston Seals, rod Seals, wiper seals and wear rings.

Rotary Oil Seals

Description

Rotary shaft seals are also known as Oil seals. They are often called grease, fluid or dirt seals. The seals conform to DIN 3760. Rubber types available are Nitrile, Viton ®, Silicone and EPDM. Main styles available are: R21 Rubber Covered Single Lip R23 Rubber Covered Lip & Wiper R4 Metal Covered Single Lip R6 Metal Covered Lip & Wiper R1 Totally Metal Enclosed Single Lip

Application

Rotary seals close spaces between stationary and moving components in mechanical equipment. They are used to help prevent lubricant escape and stop harmful contaminants from entering machinery, particularly in severe environments. They are vital components which protect all types of precision-constructed, close-fitting ball, sleeve and roller bearings.
