Straight press-fit fitting Comap 7243GW50112 — external male thread 50x4–1 1/2"

The Comap straight press-fit fitting 7243GW50112 is a press-to-connect adapter with an external male thread sized 50x4 to 1 1/2". It is intended to join press-fit piping to threaded components in metal pipe systems, providing a secure transition between a crimped connection and a male threaded outlet. The fitting is suitable for applications in heating, plumbing and industrial installations where a robust threaded connection is required.

Advantages

This straight press-fit fitting offers a compact and durable solution for converting a press-fit line to a male threaded outlet. The press-fit interface enables quick assembly without soldering, while the male thread provides compatibility with standard threaded valves and accessories. The design minimizes the risk of leaks when installed correctly and is compatible with metal piping systems used in high-temperature and pressure environments.

Suitable for

• Joining press-fit metal pipes to threaded valves and components
• Heating system installations including radiators and boilers
• Plumbing repairs and new pipework requiring threaded outlets
• Industrial pipelines where a male threaded connection is needed

Key specifications

• Type: Straight press-fit to external male thread adapter
• Thread size: 1 1/2" external male thread
• Pipe dimension: 50x4 (nominal metal pipe size for press-fit connection)
• Connection method: Press-fit (crimp) on one side, male threaded on the other
• Material compatibility: Designed for metal piping systems

How to use

Prepare the pipe end by cutting squarely and deburring the inner and outer edges to the manufacturer's tolerance. Insert the pipe fully into the press-fit side of the fitting and perform the press operation with the correct jaws and tool for the specified pipe dimension. Ensure the male thread is clean and apply appropriate thread sealant or tape if required by the application or local codes before connecting to the mating threaded component. Verify the press and threaded connections for correct seating and tightness, and test the assembly under working pressure according to system procedures.

Usage recommendations

Use certified press-fit tools and the correct jaw profile for 50x4 piping to ensure a reliable crimp. Follow system design guidelines for temperature and pressure limits, and observe local plumbing codes when applying thread sealants on the male thread. Periodic inspection after installation is recommended to confirm leak-free performance.
