The JG Speedfit White Straight Coupler 15 mm is a push-fit plumbing fitting designed to join two lengths of 15 mm pipe in a straight line quickly and securely. It provides a simple, reliable connection without the need for soldering, glue, or specialist tools.

Function & Purpose

This straight coupler connects two pieces of 15 mm pipe in a continuous run. It uses built-in grip rings and O-rings to create a watertight seal as soon as the pipe is pushed in. This push-fit design makes installation and maintenance fast and easy, and it also allows for easy disconnection if the plumbing layout needs to be changed or serviced.

Compatibility

The fitting is suitable for 15 mm pipework including copper pipe and most plastic systems that are compatible with JG Speedfit push-fit technology. It can be used in hot and cold water supply lines, central heating circuits, and other plumbing applications that use 15 mm piping.

Design & Build Quality

Finished in white for a neat appearance in exposed installations, the Speedfit straight coupler is manufactured from durable materials that can withstand typical plumbing pressures and temperatures. The push-fit connections provide secure engagement while still allowing flexibility for future adjustments.

Ideal Applications

This 15 mm straight coupler is ideal for extending runs of pipework or joining two lengths of pipe in a straight line. It’s particularly useful in domestic plumbing and heating systems where quick installation, flexibility, and ease of access are priorities, such as under sinks, behind radiators, or within service voids.
