FAQs
Is this fitting lead-free?
The Prima Plus fittings are manufactured using high-quality brass compliant with modern safety standards suitable for drinking water.
Can I reuse the compression olive?
Compression olives deform during the initial tightening process to create a seal; it is highly recommended to use a new olive if the joint is disassembled.
Is this compatible with gas lines?
Yes, these components are suitable for gas installation projects, provided the work is carried out by a qualified technician in accordance with local regulations.
What tools do I need for installation?
You will need a tube cutter to ensure a square pipe end and two adjustable wrenches—one to hold the body and one to tighten the nut.
Does this fitting come with the olive and nut?
Yes, the assembly includes the main brass body, the compression nut, and the olive required for a standard installation.
Can this be used on plastic piping?
Compression fittings are primarily designed for copper or brass pipes. If using plastic pipe, you must ensure a compatible pipe insert is used to prevent the pipe from collapsing.
Troubleshooting
The connection is leaking after assembly.
Ensure the pipe is pushed fully into the fitting and the olive is properly seated; try tightening the nut by an additional quarter turn.
The nut will not thread onto the body.
Check for cross-threading or debris in the threads; ensure the threads are aligned perfectly before rotating.
Difficulty in sliding the olive onto the pipe.
Ensure the pipe end is not flared or damaged; lightly deburring the edge of the pipe can help.

Setup, Compatibility & Care
Preparation: Ensure the 6mm pipe is cut perfectly square and is free from burrs or scratches at the insertion end.
Assembly: Slide the compression nut and olive onto the pipe, then insert the pipe into the adaptor body.
Tightening: Tighten the nut by hand until firm, then use an adjustable wrench to turn it an additional 3/4 to 1 turn; do not over-tighten, as this can deform the brass threads.
Compatibility: This fitting is specifically designed for 6mm outer diameter pipes and 1/4" BSP threaded connections. Ensure your secondary interface matches the thread specifications.
Care: Avoid using abrasive cleaners on the brass exterior. Periodically inspect the fitting for signs of corrosion or moisture if installed in humid environments.
