Overview

Polyurethane O Ring

Product Details

Description

O-rings are circular sealing elements with circular cross-sections, may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. O-ring selection is based on chemical compatibility, application temperature, sealing pressure, lubrication requirements, durometer, size and cost. We offer you a range of elastomeric materials for both standard and special applications which allow the O-Ring to seal practically all liquid and gaseous media.

Advantages

Compact design
Easy assembly
Economic solution
Symmetry that reduces the risks of an assembly error

Technical data

Temperature	-30°C / +110°C
Pressure	Up to 60 MPa in static applications Up to 25 MPa in dynamic applications
Speed	In linear applications only, up to 0.2 m/s
Medias	Mineral hydraulic oils Greases Air

Applications

O-Rings are used in a variety of fields: they are either used as sealing elements or as energizing elements for hydraulic slipper seals and wipers. Thus, the O-Ring is basically used in every field of industry including aerospace, automotive or general engineering. Today, O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, and reliable and have simple mounting.

Materials

PU (Polyurethane)

The polyurethane (PU) family has excellent mechanical features, such as wear resistance and tensile strength, and has a high elasticity compared to other rubbers.

Chemical resistance	Aliphatic hydrocarbons (propane, butane) Mineral oils and greases Silicone oils and greases Water (up to +50°C max)
Compatibility issue	Ketones, esters, ethers, alcohols, glycols Hot water and steam Alkalis, amines, acids
Temperature range	-30°C / +90°C -30°C / +110°C with special PUs

O-Ring Sizes

The o ring sizes are specified by the inside diameter and the cross section diameter. Morgan Rubber O ring seals are manufactured according to metric and imperial international standards such as GB3452.1-92, AS 568B, BS1516, DIN ISO 3601 and JIS standard. Morgan seals also accept custom sizes of almost any dimension, such as metric o rings, miniature O-rings, special O-rings with large dimensions and continuously moulded and spliced.

Cases

Morgan seals is the supplier of many famous customer, such as the Siemens Primetals, Baosteels .... The largest PU O ring we produced is the o-ring for Three Gorges Damn water-turbine generator(OD is 13000mm).
