Midland Industries CDC-300-PP Dust Cap 3 in Female Cam

Product Description

The MIDLAND INDUSTRIES CDC-300-PP is a Type DC dust cap designed to protect female cam and groove couplings from contamination, debris, and damage during storage or transport. Constructed from polypropylene, this cap fits 3-inch female cam connections and is rated for a maximum operating pressure of 100 psi at 70 degrees F. The EPDM gasket extends service range considerably, supporting gasket temperatures from -60 to 212 degrees F, while the casting itself is rated from -150 to 150 degrees F. Plumbers, industrial maintenance technicians, and fluid handling professionals install this cap to keep cam and groove systems clean and ready for service.

This dust cap is suited for use in industrial hose assemblies, chemical transfer lines, water supply systems, and general fluid handling applications where female cam and groove fittings require protection when not in use. The polypropylene body offers resistance to a wide range of chemicals, making it appropriate for both aggressive and standard fluid service environments. It is a standard component in poly cam and groove fitting systems used across commercial, industrial, and municipal settings.

Installation Notes

Installation requires no special tools - the cap seats directly onto a female cam and groove coupling by hand. Verify that the coupling and cap are depressurized and drained before installing or removing the dust cap. Inspect the EPDM gasket for wear or damage before each installation. Follow applicable industry standards and site safety protocols when working on pressurized fluid systems.
