Our sealing products


The O-ring is the most used sealing product in the world and is an efficient sealing element for both static and dynamic applications.

Rubber Seals

Though O-rings are ideal for a wide variety of applications, they are not the best solution to every design problem. We offer a wide range of alternative sealing solutions including custom made seals.

PTFE Seals

PTFE, or Poly Tetra Fluor Ethylene, was discovered in 1938 by Du Pont and has extraordinary material properties. A complete range of PTFE parts is offered by us, from Back-Up Rings to spring energized seals and custom made parts.

Metallic Seals

Metallic seals are designed to make a seal by means of a ‘first line contact’ or ‘wedge action’ between the counter face (e.g. a flange) and the packing. In order to guarantee a proper, reliable seal, it is crucial to make the right choice of profiles and material.

One of our customers had a sealing issue with an existing product. Reason for failure were very small marks on the sealing surface.

2. O-Rings Class A+

Normally an O-Ring will create a block and seals. For this specific application a controlled leakage was mandatory and standard O-Rings failed due to the existing tolerances.

3. Oil Reduction Rod Seal Improvement

One of our customers had a sealing issue with an existing rod seal. Reason for failure was unknown but oil leakage was considered to be too high.

4. One piece Oil Seal Design

During this operation you need at least two people to install the seal. Also leakage can occur and parts can damage each other during installation. For these reasons our client requested us to find a solution.

Materials of NewDealSeals


Material selection is a crucial part of the seal design. As technology evolves, applications become more and more demanding. NewDealSeals offers a wide range of sealing materials, ranging from basic elastomers to high-end custom formulated compounds/materials.Rubber is known for its memory. Rubber has the tendency to move back to its original shape after being deformed, making it an excellent sealing material for static and light dynamic applications.

Metallic Materials

Metallic materials are used in static sealing solutions. The great advantage of metallic materials is it’s high temperature range.

Our Metallic materials ►

PTFE Materials

PTFE materials have an excellent chemical compatibility. Its chemical compatibility and wear resistance makes it an excellent material for dynamic and high demanding static applications.

Our PTFE materials ►

Gasket Materials

Gasket materials vary from basic elastomer bonded fiber gaskets, to high temperature mica-based gaskets with metallic reinforcements. Gasket materials are very suitable for static applications like flange gaskets.
