Because of the numerous advantages that they come with, their popularity and the utilization is enhancing day-by-day. When it comes to their benefits, they are considered much more superior as compared to the traditional fittings.

While talking about press fittings, we often consider three profiles named M, V Press Pipe Fittings and VV Press Fittings but have you ever wondered the difference between the three profiles? Which profile is better and more advantageous?
In this blog, you will be waking through some of the facts that will help you to examine the physical as well as technical properties of the press fittings. Through this blog, you will be able to discover the differences on the basis of which you can drive a conclusion as to which profile is a better performer in the field of plumbing.
In the process of plumbing, one of the most asked questions is whether to go for M Profile, V Profile or VV Profile. In most of the general circumstances, the choice between both the profiles is made on the basis of the preference and requirements of the installer.
On the basis of technicalities, one of the most visible differences is the presence of collar in V Profile. On the other hand, M profile does not have a collar. Also, there is a difference in the jaws and chains of the profiles.
While having a discussion with the plumbing installers, one of the most frequent topics is about their preference whether they like to go for M Press Fitting, V Press Pipe Fittings VV Press Fittings. Most of the plumbing installers choose the profile on the basis of technical efficiencies.
Though the functionalities of the profiles are same and the maximum operating temperatures and pressures are also the same. The presence of the stalk on the V Press Pipe Fittings that is located after the pressing chamber makes the process of insertion of pipes an apparently easier and cleaner operation as compared to the process of insertion of pipes in the M Press Fittings. Also, the presence of stalk helps in checking the proper and effective positioning of the O-ring.
Press systems are a newer way of carrying out fittings compared to more traditional solder and screwed methods. They can offer time and cost savings as well as many other benefits.
Press-fitting systems use hydraulic press technology to provide a high-quality and easy to fit joint method. While this helps save a considerable amount of time on jobs, it can be difficult for first-timers to know where to start with more manufacturers coming on board.
Our beginner’s guide to press-fit tools provides a great overview to get you started.
When beginning to think about press-fit tools, the first question you need to ask yourself: What will I be installing?
With more systems coming onto the market, selecting the right pipe type is key.
For more traditional methods, you’ll have manufacturers of metal press systems. But plastic composite systems like Multipipe MLCP is gaining popularity.
Our hybrid pipes are a great alternative to conventional methods, which might struggle on specific jobs where flexibility and hygiene are key to a quality installation. But still offer benefits of a metal system like lower expansion rates and 100% oxygen barrier.

All pipework systems in the UK are made to a BS EN standard, but depending on the manufacturer, these standards might differ.
The most common British standard for plastic pipes is BS EN . BS EN is the multilayer (MLC) standard and BS EN is the Copper tube standards.
These standards dictate the manufacturing process, pipe dimensions and wall thickness, all of which are hugely important in selecting the right pressing jaws.
To press a joint onto these systems, you’ll need a set of compatible jaws as different pipe and fitting manufacturers use different jaw profiles.
These profiles are manufactured to the pipe dimensions and the set of ridges inside the profile help to press down on the sleeve to get a watertight joint.
There are common types of profiles used by several manufacturers which would give you the best flexibility across different pipe types. But there are also a lot of individual company profiles so making sure you have the right jaws is key to a good join. Be aware that you cannot mix jaw profiles of different manufacturers.
Below are some key examples of jaw profiles. These are cross-sections of the most popular jaws and they show the subtle differences across the profiles when they are pressed.
Most MLCP systems use U or TH profile jaws.
These profiles are used for most copper press systems on the market.
The last consideration in our guide to press-fit tools, is the pressing strength of the tool. Most press tool manufacturers have a small and a larger gun, but what exactly is the difference? The answer is that it’s mainly the strength of the hydraulic press.
Usually, the bigger the gun = the bigger the hydraulic press. Compact guns typically press up to 28/32mm pipes, with larger guns up to 108/110mm.
This means you need to consider what sizes of pipe you need to press. Some fitting manufacturers require specific press strengths for their systems, so be sure to factor this in. Our Multipipe MLCP press system requires a 15KN press tool for sizes up to 32mm and a 32KN press tool for up to 110mm pressing.
