Hygienic Blind Plugs - Overview of Groups and Features
Blind plugs are typically used when cable glands are not yet installed, when pre‑machined holes are kept as future options, or when unused openings must be closed to avoid residue build‑up and maintain hygienic integrity.
- Material and Sizes: Made from stainless steel AISI 316L and available with blue NBR, EPDM, or silicone seals. Standard thread sizes range from M12 to M32.
- Construction Details: The geometry is smooth and edge‑free, with a self‑draining design and fine surface finish that supports efficient cleaning and reduces the risk of dirt adhesion.
