Compression coupling IBP for plumbing 15 x 3/4 in, brass fitting, model 4270G015006000

Compression coupling IBP for plumbing 15 x 3/4 in is a brass fitting designed to connect metric 15 mm pipes to 3/4-inch threaded components in water supply systems. The coupling provides a secure mechanical joint without the need for soldering, enabling quick installation or replacement of sections in residential and light commercial plumbing. Delivered in bulk packaging, the fitting suits applications where a compact transition between 15 mm tubing and 3/4 in threaded fixtures is required.

Advantages

The brass construction offers corrosion resistance and long service life in potable water installations. The compression design ensures a leak-tight connection when installed to manufacturer torque and insertion depth recommendations. Its compact form facilitates use in confined spaces, and compatibility with common plumbing materials allows straightforward integration into existing pipework.

Suitable for

• Connecting 15 mm copper or plastic tubing to 3/4 in threaded valves and fixtures
• Repairing leaks or replacing fittings in household water supply lines
• Small commercial plumbing installations requiring a metric-to-imperial transition
• Situations where soldering or brazing is impractical or undesired

Key specifications

• Material: brass
• Connection type: compression to threaded
• Nominal sizes: 15 mm to 3/4 in
• Application: potable water plumbing
• Packaging: bulk

How to use

Prepare the pipe by cutting it square and deburring the end. Slide the compression nut and ring (olive) onto the pipe, insert the pipe fully into the coupling body until it seats, then hand-tighten the nut. Using a wrench, tighten the nut to the recommended grip; typically a further 1/4 to 1/2 turn past finger-tight is sufficient, but follow any specific installation guidance for the system. Check the connection for leaks after pressurizing the line and retighten slightly if necessary.

Usage recommendations

Use with compatible 15 mm copper, multilayer or plastic plumbing pipes and standard 3/4 in threaded valves or fittings. Ensure pipe ends are clean and free of damage; do not overtighten the compression nut to avoid deforming the olive or pipe. For installations in concealed or buried locations, verify long-term compatibility of materials and local plumbing codes.
