M8 Hygienic Cap Nut, A4 Stainless Steel with EPDM Seal

M8 - Hygienic Cap Nuts - A4 Stainless Steel - EPDM | Vital Parts

Our Hygienic Cap Nuts are specifically designed for applications where cleanliness and sanitation are essential. Featuring a blue seal, these nuts prevent water and bacteria from seeping into hard-to-reach areas, ensuring a hygienic and contamination-free fastening solution. The seal also eliminates metal-on-metal contact, which can create friction and lead to hygiene concerns.

What are Hygienic Cap Nuts?

Hygienic Cap Nuts are a specialized type of fastener designed to meet the highest hygiene and cleanliness standards in industries such as food manufacturing, pharmaceuticals, and laboratories. These nuts feature a smooth, self-draining design with a maximum roughness of 0.8μm Ra, limiting microscopic bacterial buildup.

The integrated blue seal acts as a barrier that prevents contaminants from entering the fastener assembly, ensuring that no bacteria or liquid can accumulate inside. This design enhances safety and extends the lifespan of the fastening system, making it an essential component in sanitary and wash-down environments.
