Ramex proud to be the official representative of Ruma Products in Scandinavia and UK.
Ruma is an 85-year old rubber company based in Hoogeveen, Holland. Ruma design, test, manufacture and supply elastomeric products to many industries including the petroleum industry where they are mostly known for their Oblique swelling seals.
For the past 5-10 years there has been an increase in demand for swellable elastomer seals for use in Oil and Gas wells. Swelling seals have proven to be useful in creation of compartments in long open-hole liner systems as well as for fracturing formation while also being a considerably cheaper and simpler alternative to the traditional mechanical packers.
Did you know that during the second world war swelling elastomers were used by the military on aircraft fuel tanks as a self-sealing mechanism?

Why chose Oblique?
Ruma Oblique products are certified to ISO-29001 (as well as ISO 9001 and ISO 14001) for swelling seals.
The knowledge required to do this and the test facilities are all in-house as is the research and development programs.
Ruma’s laboratory is one of the best in the world on swelling elastomer technology and has the most extensive selection of elastomer compounds and combinations of these.
The first water swelling elastomer (E-zip seal) was developed by Ruma laboratory for PDO Oman
The first oil swelling seal used on the NCS was developed by Ruma for Easywell/Hydro in 2000.
“Ruma Products is unique in the industry in being able to design and compound its own elastomers, design its own swelling articles made from those elastomers and then have its own facility to manufacture these articles”.
To Be the best in the world, with the best products and the best prices.
How do we achieve this? QUALITY 100%
Oblique swelling seals
Ruma Oblique swelling seals are colored for easy identification.
Blue swells in water. Red swells in oil. Black is a hybrid elastomer which means it will swell in both oil and water.
