There are thousands of o-rings for your choice. All of them are made of high quality and eco-friendly rubber, silicone, NBR/FKM etc materials. We have the mature technical reserve for the solution of ultra-high/low temperature, ultra-high pressure, highly corrosive & other special working condition. The o ring are widely used in construction machinery, automobile, automation equipment, petroleum, water conservancy, chemical engineering,aviation & other area.Cooperated with famous enterprise, like SANY, CSR, DORMA, LAP, LA CAPITAL etc. Most importantly, they are in directly factory price.

O-rings are actually really easy to measure. All you need to do is measure the internal diameter (ID) or outside diameter (OD) and the width or cross section (C/S) of the o ring. The diagram shows exactly where these dimensions are to be found. Once you have these measurements you then need to decide if the size you need is listed below or if the best fit will be a metric oring. Once you have the AS-568 dash size you need, select the compound link at the bottom of the page to place your order.
To calculate an o-ring's outside diameter (OD) you may use this formula: 2(CS) + ID = OD
If you have the OD and need to find the ID use this formula: OD - 2(CS) = ID

To find your O-Ring, At first choose the materials and than all size which require

On the website: you can find all the spare parts (O-Ring) for Rotork, Biffi, Betis, Fisher, Kent Introl, Masoneilan, STI,etc. actuators, just write the model and we provide for you the O-Ring, including Buffer Seals,Wiper Seals,Rod Seals,Piston Seals.

How to calculate O-Ring cord length needed: ( ( OD + ID ) / 2 ) x Pi = length Pi=3.14159 Inside Diameter (ID) = Outside Diameter (OD) - twice the cross section (C/S) ID = OD - (2 x C/S)

The cord or is available in multiple thicknesses and materials.

MB Gaskets can guarantee the supply from a few meters up to large quantities. The available materials include:

• NBR
• VITON
• TRANSPARENT SILICONE
• RED SILICONE
• BLUE SILICONE

This extrusion process used to make o-ring cord has many advantages, however, it can be difficult to achieve a consistent, precise thickness throughout the length of the cord. Molded o-rings, on the other hand, tend to have very tight cross-sectional tolerances due to the precise manufacturing capabilities of compression or injection molding. Because of this, the Association for Rubber Products Manufacturers (ARPM) has produced industry-accepted standards for the cross-sectional tolerances of extruded rubber o-ring cord.
