Polypropylene cam and groove coupling
Polypropylene camlock fittings (or cam and groove couplings) are made from polypropylene reinforced with acid-resistant fiberglass, which makes PP Camlock coupling has excellent tolerance to most corrosive acids, bases, fertilizers, solvents, and wastewater. The black polypropylene camlock hose fitting is the best-priced lightweight cam and groove coupling available. Ideal for use in conditions where it is constantly subject to moisture. They are typically used in low-pressure suction or discharge hoses of firefighting pumps, IBC (intermediate Bulk Container) containers, and other applications that need quick connect or disconnect operations. It is widely used in inhalation/discharge hoses for agricultural or industrial applications.
All polypropylene cam & groove fittings are NOT for use with compressed air or gases. Polypropylene dust caps and plugs should not be used in pressure applications.
The working pressure below is measured at ambient temperature. When temperature increases, the operating pressure for polypropylene will decrease sharply.

Polypropylene camlock couplings are widely used in fluid transfer applications. They provide a quick and reliable connection between hoses or pipes, allowing for efficient fluid transfer without the need for tools. With their lightweight and durable polypropylene construction, they offer excellent chemical resistance and ease of use. It is important to choose the appropriate size and type of coupling for your specific application and follow proper installation and maintenance procedures to ensure optimal performance.
Frequently Asked Questions
What is a polypropylene camlock coupling used for?
Polypropylene (PP) camlock couplings are used for chemical transfer, irrigation, water supply, and applications where corrosion resistance or lower cost compared to metal couplings is important. They are lightweight and do not rust or corrode in most chemical environments.
What chemicals is polypropylene compatible with?
PP is resistant to most inorganic acids, alkalis, salts, and many organic chemicals. It is commonly used with fertilizers, pesticides, irrigation chemicals, and mild industrial chemicals. It is not suitable for aromatic hydrocarbons, chlorinated solvents, or concentrated oxidizing acids.
What is the maximum working pressure?
Working pressure is generally rated at 150 PSI (10 bar) for smaller sizes, with larger sizes rated lower. PP couplings have lower pressure ratings than equivalent metal couplings and should not be used in high-pressure systems.
What sizes are available?
Available in sizes from 3/4 inch to 4 inches (DN20 to DN100). All standard camlock types (A through F) are available.
Are they interchangeable with metal camlock couplings?
Yes. PP camlock couplings are dimensionally compatible with MIL-C-27487 / ISO 16028 standards, ensuring interchangeability with aluminum, stainless steel, and brass camlock couplings of the same size.
What temperature range do PP couplings support?
PP couplings operate between −10°C and +80°C (14°F to 176°F). Above 80°C, PP softens and loses pressure rating — do not use for hot liquids or steam.
What is the minimum order quantity?
Standard MOQ is 100 pieces per type and size. Mixed types within the same size can be combined to meet minimums.
