The Type DC Polypropylene 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-strength, glass-reinforced polypropylene, it is corrosion-proof and highly resistant to acids, alkalis and a wide range of aggressive chemicals, protecting fitting threads and sealing faces between uses in irrigation, spraying, fertiliser and chemical transfer, and general agricultural fluid handling.
