The PrimaPress Pressfit MI Coupler is designed for professional plumbers and contractors seeking a reliable, flameless solution for joining copper pipes in water, gas, or glycol systems. Its primary benefit is a high-security leak-before-press detection feature that prevents costly oversights during installation, though it does require the use of specific M-profile pressing tools for a proper connection.

Yes, PrimaPress fittings are rated for gas applications, provided they are installed in accordance with local gas safety regulations.
No, this fitting is designed specifically for M-profile press tools. Using incorrect profiles will result in an insecure joint.
Each fitting is covered by a 50-year manufacturing defect warranty.
No, once a press fitting has been crimped onto a pipe, it cannot be reused and must be replaced if removed.
The O-rings are factory-lubricated. Using additional oil or grease can damage the seal and should be avoided.
Verify the pipe was inserted to the correct depth and check that the fitting was pressed using the correct M-profile jaws.
Ensure the pipe end is deburred and perfectly round. If the pipe is deformed, use a pipe sizing tool before insertion.
To install the PrimaPress MI Coupler, first cut the 15mm copper pipe square and ensure it is free of all burrs and surface scratches. Mark the insertion depth on the copper pipe as recommended by the press tool manufacturer to ensure full engagement. Insert the pipe into the coupler until it hits the stop. Position the M-profile press tool jaws squarely over the fitting's beaded section. Activate the tool until the full cycle is complete. For care, avoid using abrasive cleaners on the fitting. Always ensure the system is pressure tested before finalizing insulation, and consult local building codes for gas versus water installation requirements.
