Yes, the Prima Plus DZR coupling is rated for gas applications, provided the installation is performed by a qualified engineer.
Generally, compression fittings do not require PTFE tape on the olives. The mechanical seal between the olive and the pipe is sufficient if the surfaces are clean.
While the body can be reused, it is highly recommended to use a new olive every time you break and remake a connection to ensure a leak-proof seal.
Yes, it is WRAS approved, meaning it is certified safe for use in contact with potable (drinking) water.
You will need a pipe cutter or hacksaw, a deburring tool (or file), and two adjustable spanners to tighten the nuts.
Yes, all Prima Plus components are manufactured in Britain to EN 1254 standards.
Ensure the pipe is cut square and deburred. Tighten the nut by another quarter to half turn, being careful not to overtighten.
Check that the threads are free from debris or paint; if the olive is damaged or deformed, replace both the olive and nut.
The pipe may not be inserted deep enough into the coupling body. Remove, check for burrs, and re-insert until it bottoms out.
To install, ensure the copper pipe ends are cut square, deburred, and free from dirt or paint. Slide the nut and the olive onto the pipe, insert the pipe fully into the fitting body, and tighten the nut by hand before finishing with a spanner. For gas applications, always check with an industry-certified professional to ensure compliance with local safety regulations. While the fitting is maintenance-free once correctly installed, it is recommended to periodically inspect joints for any signs of surface oxidation or weeping. Avoid using chemical pipe dopes or excessive thread sealant as they are generally unnecessary with properly seated compression olives.
