## Summary description

Straight press-fit coupling Comap with press-fit end and external thread, model 7243GW1812, nominal size 18x2-1/2. Designed for joining pipes using a crimp/press installation method while providing an external threaded connection for fittings or valves. Suitable for plumbing and heating systems where a combination of press and threaded connections is required.

## Long description

The Comap coupling straight press-fit end with external thread 18x2-1/2 (model 7243GW1812) is a metal connector designed for joining press-fit pipe systems with an integrated external threaded outlet. It combines a press-fit connection on one side and a male thread on the other, enabling a transition between crimped pipe lines and threaded components such as valves, fittings or meters. The coupling is intended for use in plumbing and heating installations where reliable, leak-resistant transitions are required.
Advantages
This straight coupling offers a secure press-fit joint that ensures consistent mechanical strength and tightness when installed with compatible pressing tools. The external thread provides a standard, reusable connection point for attaching fittings or valves without additional adapters. Manufactured by a specialist brand for building services, the part supports quick installation, reduced risk of soldering or welding, and long-term resistance to typical domestic heating and plumbing conditions.
Suitable for
Joining copper or compatible press-fit pipe systems to threaded valves and fittings
Residential and commercial heating distribution lines
Plumbing service connections where a threaded outlet is required
Retrofitting or repairs where conversion from press to thread is needed
Key specifications
Connection type: press-fit on one end and external (male) thread on the other
Nominal pipe size: 18 x 2-1/2 (press-fit x thread dimension as specified)
Material: corrosion-resistant metal suitable for potable water and heating systems
Compatibility: designed for use with standard press tools and compatible press fittings used in building services
Operating environments: potable water, central heating and similar building utility systems
How to use
Prepare the pipe by cutting square and deburring the internal and external edges. Slide the press-fit coupling onto the pipe end until the correct insertion depth is reached, following the marking or stop on the fitting. Use a compatible pressing tool and jaw sized for 18 mm press fittings to perform the press operation according to the tool and fitting manufacturer instructions. Once the press connection is made, thread the external male end into the mating female fitting, valve or adapter using appropriate sealing method for threaded joints (for example, PTFE tape or approved joint sealant) and tighten to the recommended torque for the system components.
Usage recommendations
Verify material compatibility with the pipe and system fluid, follow local plumbing codes, and use certified press tools and jaws. Inspect the pressed joint and threaded connection for leaks after initial system pressurization and during commissioning. For installations in concealed locations or where freeze risk exists, consider additional protection and follow manufacturer guidance for installation and maintenance.
