Dust Caps are essential protective accessories used to cover the ends of hydraulic hose fittings, ports, and couplings when not in use. Their primary function is to prevent the ingress of dust, dirt, moisture, and other contaminants that can damage sensitive hydraulic components and compromise system performance. Commonly used in construction, agriculture, and industrial applications, Dust Caps help maintain cleanliness and extend the service life of hydraulic equipment. Available in various sizes and materials—including plastic, rubber, and metal—they are easy to install and remove, offering a simple yet effective solution for protecting your hydraulic system.
