At MEREFSA, we are manufacturers of high-quality sleeves, offering solutions tailored to various industrial applications. We have a permanent stock of a wide range of silicone raw material formats and thicknesses, allowing us to guarantee immediate manufacturing service and offer highly competitive delivery times within the market.
Welded silicone sleeves
The silicone sleeves we manufacture at our facilities stand out for their high resistance and excellent finish. They are produced from welded silicone sheet, and the manufacturing process varies depending on the sleeve wall thickness:
- Overlap Welding: applied to sleeves with a wall thickness between 0.3 mm and 1.5 mm.
- End-to-End Welding: in this method, the ends of the sleeve are joined without overlapping, used for wall thicknesses from 2 mm to 15 mm or more.
The joining of our sleeves is done through an exclusive hot vulcanization process, ensuring greater adhesion and tensile strength. As a final step, we reinforce the joint with an external overlap strip, ensuring a perfect and durable finish.

Essential characteristics
Our designs guarantee a flawless sealing and product transfer solution, adapting to the specific needs of each application.
- Variety of sizes: we manufacture straight, conical, or custom geometries according to customer requirements.
- Variety of compounds: we have a permanent stock of compact silicone sheet in white, tile red, blue, and black colors, with thicknesses ranging from 0.3 mm to 12 mm and hardnesses of 40, 50, and 60 Shore A. Upon request, we can manufacture in other hardnesses, colors, and qualities. Additionally, we offer specialized options such as silicone for very high temperatures (THT) and detectable silicone, among others.
- Certified material: we use food contact compliant silicone, meeting FDA regulations, ensuring safety and quality in industrial and sanitary applications.
