Type B nylon cam and groove fittings include a female cam x male NPT connection. Type B camlock fittings are most often used with Type F adapters of identical size. They can also be used with Type A, E, and F adapters and Type DP dust plugs. Nylon withstands higher temperatures than polypropylene, won't scratch delicate surfaces, and resists corrosion and changes in humidity. Type B nylon camlock couplings are used with wastewater treatment, irrigation, and food processing.

Type DC nylon cam and groove dust caps include finger rings and handles (also known as cam arms). Type DC camlock fittings are most often used with Type A, E, and F adapters to seal the end of the connection, preventing leaks and keeping debris and materials out of connection. Nylon withstands higher temperatures than polypropylene, won't scratch delicate surfaces, and resists corrosion and changes in humidity. Type DC nylon camlock couplings are used with wine production, pharmaceutical processing, and chemical storage.

Type D nylon cam and groove fittings include a female cam x female NPT connection. Type D camlock fittings are most often used with Type A adapters of the same size. They can also be used with Type E and F adapters and Type DP dust plugs. Nylon withstands higher temperatures than polypropylene, won't scratch delicate surfaces, and resists corrosion and changes in humidity. Type D nylon camlock couplings are used with petroleum products, reverse osmosis systems, and food processing.
