Metal Press Fittings

We offer a unique range of metal press fittings to create permanent non-demountable systems from sizes 16-32mm, which with the introduction of our patented ‘D’ ring construction makes for the most secure plumbing connections.

Why use Maincor press fittings?

  • Less chance of errors – The fitting will leak if the fitting is not pressed. This means that there is less chance of work being covered over before the leak is discovered, reducing warranty costs for the installer.
  • High quality construction – The fitting has one large
    O ring which is much more substantial than an ordinary O ring. This means it is much harder to dislodge or damage as the pipe goes into the fitting.
  • Increased flow – The larger internal bore allows for significantly increased flow.
  • Viewing windows – Allowing the installer to check the pipe is inserted correctly reducing the chances of an error.
  • Ease of installation – The pipe goes into the fitting smoothly and quickly, reducing installation time.

Composite Press Fittings

Maincor Composite Press Fittings provide a simple and cost effective method of jointing MLCP in plumbing applications for both domestic and commercial projects. The fittings allow for pipe connections of permanent non-demountable systems from sizes 16-32mm, and are suitable for use in both hot and cold water plumbing systems and heating applications.

Key Features
The fittings bodies are made from polyphenylsulfone (PPSU) which offers exceptional hydrolytic stability, and toughness superior to other commercially-available, high-temperature engineering resins. This resin also offers a high deflection temperature and outstanding resistance to environmental stress cracking. The polymers are inherently flame retardant and provide excellent thermal stability. The press sleeves are made of stainless steel and are designed to be used in conjunction with Maincor’s range of Press Tools.

The fittings are manufactured in Germany with production certified in accordance with ISO 9001 & ISO 14001. The fittings are tested in accordance with UK requirements and further European approvals include Kiwa and DVGW.

Compression Fittings

Suitable for 10mm, 15mm, 22mm and 28mm, Maincor Compression Connectors are the simple, easy way to connect multilayer pipe to copper compression fittings and a wide range of valves, radiator connections and threads with a straight BSP connector. They form a handy repair coupling.

Maincor Multi-fit

Our Multi-Fit range is a simple and effective way of connecting Maincor MLCP to potable plumbing systems, heating, underfloor heating, kitchen and bathroom appliances, in fact a “go to” connector for almost any application. The most versatile connector you will ever use!

Multi-Fit connectors are simple to install saving the installer both time and money, no special tools are required, all you need are pipe cutters, a bevelling tool and an allen key. The pipe is cut to length and bevelled at the end, the fitting is inserted into the pipe and then the allen key is used to screw the thread into place (a Maincor Multi-Fit tool is also available). Once the pipe is fully visible in the viewing window the connection is made – simple.

Multi-Fit connectors are available in a wide range of sizes with ½”, ¾” and 1” compression nut connections, and are supplied with both an o-ring for conical seats and a flat washer for flat face applications. The connector comes with a female thread to connect to appliances, manifolds and other connections. Multi-Fit is also fully demountable should a layout change be required to the system at a later date.
