Rubber molded products for oilfield service applications

Custom Molded Parts


Our compression molded rubber products can be found in exploration and production equipment all over the world. We offer an extensive list of elastomers specifically formulated for the harsh environments typically seen in oilfield service applications. This includes compounds that offer resistance to temperature, extrusion, rapid gas decompression, and superheated steam. We also offer compounds that are both NORSOK M710 and API 6A certified.

Why choose KC Seals for your molded products

Compression Molding

In-House mold making

Setup fees can be a major deterrent when deciding to move forward with a project. KC Seals makes it far more affordable by making all our compression molds in-house, saving you time and money. In addition, your IP stays under one roof and will not get shipped off to another machine shop with which you have no familiarity.

Our Super-Sub program is an affordable multi-sourcing arrangement that limits the negative impacts of potential disruptions. It’s a no setup fee, and minimum commitment on your moderate to high usage production rubber parts. Book a meeting to learn more.
