Bolted coupling 1/2x16 with female thread
Code: PEX.Z.GW16X1/2Related products
Product detailed description
Bolted couplings are commonly used in residential and commercial building projects for connecting plastic-metal composite pipes in water and heating systems. These fittings are particularly useful in underfloor heating, radiator circuits and potable water distribution. Installers working with PEX-AL-PEX or PE-RT-AL-PE-RT pipe systems often require secure and reliable connections that can be assembled without specialized crimping tools. Bolted couplings offer a practical alternative by allowing installation with standard wrenches, reducing the need for additional equipment and training. They are especially suited for systems where flexibility and ease of assembly are required, such as in retrofitting or complex piping layouts.
When selecting a bolted coupling, it is important to consider the pipe dimensions, operating pressure and temperature range. This coupling is designed for 16x2 mm PEX-AL-PEX pipe and can handle pressures up to 10 bar and temperatures up to 95°C. The materials used, including tinned brass and EPDM seals, ensure durability and resistance to corrosion, making it suitable for long-term use in both heating and water systems.

Installation and connection
Installation of this bolted coupling involves inserting the prepared pipe into the coupling body and tightening the nut using a standard wrench. The coupling features a 1/2 inch internal thread, which allows for secure connection to threaded fittings or valves. It is important to ensure that the pipe is properly aligned and that the sealing rings are undamaged before tightening. Common installation mistakes include over-tightening, which can damage the sealing rings, and using the wrong thread type. Always verify the pipe dimensions and thread compatibility before assembly.
Compatibility and accessories
This coupling is compatible with PEX-AL-PEX, PE-RT-AL-PE-RT and other composite pipe systems. It is recommended to use stainless steel manifolds for optimal performance. Additional accessories such as wrenches and sealing compounds may be required for installation. A related product is the bolted coupling 1/2x16 with external thread, which can be used in different connection configurations.
Technical background for designers
The bolted coupling operates by compressing the sealing rings between the pipe and the coupling body to create a watertight seal. The tinned brass body and nut provide resistance to corrosion and ensure long-term stability. The EPDM sealing rings offer flexibility and durability, adapting to minor pipe movements and thermal expansion. The coupling is designed to integrate into both heating and water distribution systems, where it can withstand the mechanical and thermal stresses associated with these applications. The choice of materials and design ensures that the coupling maintains its integrity over time, even under continuous operation.
Service and operation
Regular inspection of the coupling is recommended to ensure that the sealing rings remain intact and that there are no signs of leakage or corrosion. If any damage is detected, the coupling should be replaced immediately. No specific service intervals are required for this coupling, but it is important to monitor the system for any changes in pressure or temperature that could affect performance. Proper installation and use of compatible materials will contribute to the coupling's longevity and reliability.
