Omniseal® Metals

Metal Machined Seals

Machined seals such as our K-Seal are excellent metal seal solutions for high pressure and high load environments but are different from formed metal seal solutions in that they can be machined with a thicker wall to handle more extreme pressures. In addition, with our flexible capabilities and expertise to understand your machined metal seal requests, we can provide you the best resistant metal seal solution - from aluminium to complex nickel alloys.

Different materials can be machined depending on your needs, and our coating expertise can improve the performance of the machined parts. In addition, we offer K-Seals for the AS5202 port often found in space applications.

These machined seals are used in extreme environments related to high temperature, high pressure, load or corrosive media.

Is this Component PFAS-Free*?

By its nature, this component is PFAS-Free*.

Contact our engineers to learn more and start the discussion on how we can support you to meet the requirements of your application.

* PFAS-Free here means we do not intentionally add PFAS material in the product, but does not exclude the possibility of traces, as these materials are common in the environment.

Seal Function & Motion



A  distinct feature of machined parts is the wall strength and load resistance, which may be applied to the reusability of the part in specific cases. Our experts can help you with simulation tools developed to understand the behavior of the part. Function is also dependent on the hardware mating surface flatness.


Design (Hydraulic Replacement)

With our machined metal seals solutions, we can produce the standard K-Seal for the hydraulic standard fitting AS5202 in limited volumes and all dimensions. We offer two different designs for K-Seal replacements that are more economic and have a shorter lead time.
