O-Rings of NewDealSeals
An O-ring is a torus shaped seal placed between two parts to prevent the passing of fluids and gasses. It is an efficient sealing element for both static and dynamic applications. In industries from aerosol to aerospace, O-rings are the most commonly used seals in the world. Why? Because they are effective, economical, and easy to use.
Although the O-ring is a simple sealing concept, there are many factors to take into account when selecting the right O-ring for a specific application. Our O-ring Technical Handbook explains the factors involved when selecting the right O-ring.
We deliver O-rings according to or any custom size/tolerance required. O-rings are also available in accordance with different standards(AS 568A, DIN 3701, BS 1806/ BS 4518, JIS B2401, JIS NFT47-501, SMS 1568 and ISO 3601) and with various approvals (KTW, USP, NSF 51 61, WRC, WRAS, FDA, R67 01).
The selection of the right material is crucial for the appropriate applicability of an O-ring. NewDealSeals has all basic materials available with more than 500 rubber compounds. We gladly advise you with making the right choice.
Presented below, the most commonly used O-ring materials. All other basic materials such as FVMQ, HNBR, PU or CR can be found on our rubber materials page.

How does the O-ring work
An O-ring is an elastic part placed between two parts and then squeezed to fill up the gap between the two parts. When placed under pressure, the O-ring is forced to “flow” within the groove toward the clearance gap. As the O-ring flows against the gap, it produces zero clearance and prevents the sealed substance from escaping.
Staying in shape
An important factor in the effectiveness of any O-ring is its memory, or ability to remember its shape. O-rings are made to always try to regain its original shape despite being squeezed and/or distorted by pressure. O-rings are used for a wide range of applications and environments. An O-ring is a simple concept, but there are over 20 types of materials with more than 500 compound types to choose from in virtually any possible size. The right material and design choice is critical for staying in shape.
O-rings are ideal for a wide variety of applications but they cannot solve every sealing design project. For this purpose NewDealSeals has a range of alternative seals available that can be used into standard O-ring groove designs.
