The Type DC Stainless Steel Camlock Dust Cap (Dust Cap) is a protective cap that clips over an unused female camlock coupler to keep dirt, moisture and debris out of the sealing face when the fitting is not in use. Made from high-grade 304 stainless steel, it is corrosion-proof, food-safe and built to handle high temperatures, high pressure and aggressive chemicals, protecting fitting threads and sealing faces between uses in food and beverage processing, wineries and dairies, pharmaceutical transfer, marine use and heavy-duty industrial fluid transfer.
