Plug 22 CU B Press P5290 02200000

Application and Material

The 22 CU B Press cap (code P5290 02200000) is a closing component dedicated to copper piping systems, designed for permanent joining via pressing. This product is essential when a hermetic termination of an installation circuit with an outer diameter of 22 mm is required, for example, during the final assembly of water or heating pipelines. It is manufactured from copper of grade Cu-DHP (CW024A), i.e., phosphorus-deoxidized copper with 99.99% purity, guaranteeing high corrosion resistance and long-term durability. This material selection is standard in professional sanitary installations, ensuring the chemical stability of the water conveyed within the system.

Construction and Installation Method

This component does not feature a drain valve or air vent; its function is limited to permanently sealing the end of the pipe. The connection is achieved via a pressing end (V-profile), which requires the use of a dedicated pressing head compatible with the B Press system. Unlike threaded solutions, this method eliminates the risk of leaks resulting from improper tightening or seal degradation over time, provided the appropriate installation tool is used. The seal material is ethylene-propylene-diene monomer rubber (EDPM), characterized by resistance to high temperatures and aging, which is crucial when working with hot domestic water or central heating systems. The connection surface remains in a raw state, facilitating visual inspection prior to pressing and ensuring optimal metal-to-metal contact during fitting deformation.

Operating Conditions and Performance Parameters

The product is designed for use in pressure systems, withstanding a maximum working pressure of 16 bar at 20°C. This is a standard value for most residential and industrial installations, allowing safe use of the cap in water supply and low-temperature heating systems. It should be noted that despite high mechanical strength, the cap does not hold FM, LPCB, or UL certifications; its application is limited to installations compliant with European standards for copper and bronze (PN EN 1254).

Due to its simple construction and lack of moving parts, this cap minimizes the risk of mechanical failure after installation. It is a "permanent" solution – once pressed, disassembly is impossible without cutting the component, which necessitates precision when planning the installation route. For the installer, this means faster installation without the need for additional seals or assembly pastes; for the end user, it ensures circuit tightness throughout the entire lifespan of the installation. Key data such as pipe diameter 22 mm, body material Cu-DHP, and seal EDPM confirm its suitability for standard hydraulic circuits operating at pressures up to 16 bar.
