John Guest Black M Adpter, 3/4" CTS MIPT

The John Guest Black Male Adapter, 3/4" CTS x MIPT, from Reliance Worldwide Corporation belongs to the UV-resistant black PEI Twist and Lock range, engineered specifically for the most common water filtration and water treatment applications, including point-of-entry filter housings and water conditioning. Beyond treatment work, it also serves plumbing repair, remodel, marine, and RV needs, making it a genuinely versatile fitting.

This adapter connects 3/4" CTS pipe to a male iron pipe thread, mating push-fit tubing systems to threaded ports. The Speedfit push-in system requires no tools to assemble, delivering substantial installation time savings, and the connection is fully demountable without damaging the pipe or fitting. Manufactured from high-quality engineered PEI plastic with EPDM O-rings, it ensures a leak-free connection across a wide range of conditions.

Features of the Male Adapter

• Push-fit connections for fast, tool-free assembly
• Suitable for use with PEX, CPVC, and copper pipe
• Rated for hot and cold water and hydronic heating applications
• Lead-free and non-toxic
• Truly demountable without damage to pipe or fitting
• Corrosion-free with no scale build-up and no risk of fire or flames

The black UV-resistant body suits exposed and outdoor installations where standard fittings might degrade under sunlight over time. Because the system requires no torch or soldering, there is no risk of fire during installation, a meaningful safety advantage when working near finished surfaces or in confined spaces. To install, wrap the male thread with PTFE tape and tighten it into the port, then cut and deburr your 3/4" CTS pipe and push it fully into the fitting until it seats. A gentle tug confirms the grip. When servicing is needed, the demountable connection comes apart cleanly and refits just as quickly. For reliable, versatile point-of-entry water treatment connections that install in seconds, this John Guest black male adapter is a professional-grade choice.

Within the JG Twist and Lock range, this male adapter works alongside the matching black unions and elbows that share the same engineered design, letting you build a complete point-of-entry layout from one coordinated family of fittings. The combination of speed, safety, and broad pipe compatibility makes the range a favorite for filter and softener installations where downtime and torch work are best avoided.
