Rubber O Rings - Viton, Silicone, Polyacrylic, Hnbr, Cr Materials | High Durability, Precision Dimensions, Suitable For Static And Dynamic Sealing Applications

STANDARD ASTIND ' O' RINGS

TO BS 4518 : 1969 AND SMS 1588 as also BS 1806 ( Metric size in mm.)

OUR 'O'RING

We have been manufacturing ' O' Rings of high quality for both Aircraft and Industrial

STANDARDS

applications.

The need for standardisation has been felt by the consumers for a long time. It is as

an answer to this, that we standardised the same to British Standards BS 4518,

Swedish Standards SMS 1588 and BS 1806.

All these ' O' Rings will be availiable with us ex-stock or very early deliveries can be

arranged.

OUR MATERIAL

Our standard material is: Auto Steel Grade - 36170 with 70 - 75 Shore -A..This grade

STANDARDS

of Nitrile Rubber is found suitable for majority of applications.

SELECTION OF

However, the advancement in Rubber Technology has made it useful to study each

MATERIAL

working condition separately and prescribe suitable material for best results in each

different case.We offer a full range of Natural and Synthetic Rubbers for diversified

applications and to suit individual requirements.

GROOVE SIZES

Normal groove sizes for different sizes and different applications can be suggested

by us on request. These have been worked out and we expect to print the catalogues

very soon.

STATIC

The designer must take care in specifying the tolerance so that minimum squeeze on

APPLICATION

ring section and maximum diametral clearances indicated in the tables are not

exceeded.

DYNAMIC

Greater friction and wear will be the result of excessive squeeze on the ring. However,

SERVICE

excessive clearance in metal parts will result in extrusion of the 'O' Ring under

pressure.

Our engineers and chemists are always available without any obligation whatsoever,

to guide the Customers in every way.

Kindly send us full drawings of the parts, showing space available to enable us of

being help. You may please indicate whether you are willing to change the metal

parts, if necessary, to provide housing etc.The direction of fluid pressure may also be

indicated as also a brief description of the mechanism.

HOW TO ENQUIRE?
