In tap water transportation, there is no need to consider the corrosion allowance of M-profile stainless steel fittings. To minimize the cost of M profile stainless steel fittings, all stainless-steel press fitting producers have traditionally advocated “thinning.” Choosing the right fittings is crucial to ensure a reliable and efficient system when it comes to plumbing and HVAC installations. M and V Press fittings have become increasingly popular in recent years due to their ease of installation and reliability. However, there are two common types of press fittings, M or V press fittings. Understanding the difference between them is essential in selecting the correct type of fitting for your project.

M profile press fittings are known for their reliability, durability, and ease of installation. But have you ever wondered how these fittings are manufactured? The manufacturing process for M profile press fittings involves several key steps that help ensure the fittings’ quality and integrity. The first step in the manufacturing process is to select high-quality raw materials, such as brass or stainless steel, suitable for press fittings. The raw materials are then formed into the desired shape using various techniques, such as forging or casting. M profile press fittings are complicated and require high precision; it will take a lot of labor and material to make the inner hoop groove of the O-ring sealing, which makes the price relatively high; installation quality is closely related to the earnestness of the operators, construction requirements are strict and meticulous, and it is not suitable for extensive construction site management. Forming stainless-steel press fittings is a sophisticated manufacturing process that must be welded according to the goods’ various applications and materials. Stainless steel press fittings must be included according to specific techniques, and the forming must be done gradually under set pressure.
The V profile press fitting is defined as a pipe connection with clamps on both sides of the pipe socket’s U-shaped groove that uses the metal material’s stiffness and the elastic compression ratio principle of the sealing material while making full use of the length of the socket. V profile has the following advantages: V shape fittings inherit all of the benefits of press fittings while compensating for the disadvantages of M shape press fittings in usage. Among residential thin-walled metal pipe connections, V shape fittings are one of the most reasonable and dependable options. It is widely employed in various system disciplines, including direct drinking water, tap water, cold and hot water, heating, and cooling, fire sprinklers, gas, etc.
The M profile press fitting is a type of press fitting that features a unique shape that allows it to create a secure and reliable connection between pipes. The M profile press fitting consists of a cylindrical body with two grooves on opposite sides, which makes it easy to install onto pipes. The M profile press fitting is compatible with various pipes, including copper, stainless steel, and PEX. One of the significant benefits of the M profile press fitting is its ability to withstand high pressure and temperature. It makes it an ideal choice for commercial and industrial applications where pipes must handle high-pressure fluids and gases. The M profile press fitting is also resistant to corrosion and chemical damage, which makes it a durable and long-lasting option.
The V profile press fitting is another type of press fitting that is commonly used in plumbing and piping systems. This type of fitting features a unique V-shaped profile that creates a tight seal between pipes. The V profile press fitting is made of high-quality materials such as stainless steel, brass, or copper, which makes it resistant to corrosion and damage. One of the significant benefits of the V profile press fitting is its flexibility. It can be used with various pipes, including copper, stainless steel, and PEX. The V profile press fitting is also easy to install and requires minimal tools, making it a popular choice among DIY enthusiasts.
Press Fittings has variations like M Profile and V Profile. Distinguish their benefits and know which one is best for you. Plumbers and installers widely use press fittings all over the world for the installation of pipes and fittings. Because of their multiple benefits, their popularity and use are growing daily. Compared to traditional fittings, they are deemed far superior in advantages.
Let’s go through some of the topmost benefits of press fittings;
The V-shaped groove on the fitting body creates a secure and leak-free connection by gripping the pipe tightly. When the pressing sleeve is crimped onto the appropriate body using a press tool, it compresses the pipe onto the fitting body, which causes the V-shaped groove to grip the pipe tightly. The pressing sleeve also visually indicates a secure connection by indenting the sleeve around the pipe and fitting the body.

M profile press fittings are a type of plumbing fitting that use an M-shaped profile to create a secure and leak-free connection between pipes. These fittings consist of two parts: the fitting body and the pressing sleeve. The fitting body is made of brass, copper, or stainless steel and has an M-shaped groove on the inside. The pressing sleeve is made of stainless steel and is used to compress the pipe onto the fitting body. The M-shaped groove on the fitting body creates a secure and leak-free connection by gripping the pipe tightly. When the pressing sleeve is crimped onto the fitting body using a press tool, it compresses the pipe onto the fitting body, which causes the M-shaped groove to grip the pipe tightly. The pressing sleeve also provides a visual indication of a secure connection by indenting the sleeve around the pipe and fitting body.
There are several benefits to using M profile press fittings over traditional fittings. Some of these benefits include:
The use of press fittings and the most popular profile M is increasing exponentially. The M-Profile fitting is becoming the profile of choice for engineers including, M&E contractors and heating engineers alike.This is due to the wide range of different types of fittings that are available. It may not be common knowledge but there are specific M-profile press fittings suitable for potable water, open and closed circuits. These circuits would include heating and hot water and cold mains water. In all cases it is recommended to use a press fitting that is certified and tested thoroughly to make sure it is not substandard. The standard for potable water in the UK is WRAS and if certified all fittings would have a specific WRAS number. With the unique way that press fittings work is that it is a single press and closure of a joint without using any flames, solder or flux. This is ideal where there is a requirement for no hot work or in a tight space that would be dangerous to use a flame.
This type of connection requires a press tool, for instance a Z-Press from Zupper (www.zpress.co.uk) with M-Profile jaws. The mechanical joint is successful many times
over without the need for return visits or errors with soldering. Press fittings also are much thicker walled than conventional end feed and soldering fittings. This would explain why they are more expensive as they contain more material and are better manufactured. This reflects in their longevity and fit, as a user is less likely to experience a loose or misshaped fitting. It is also not being deformed or changed through heating and the addition of toxic and harmful, corrosive substances like flux. Flux also plays a role in creating pin holes in radiators and solder can easily block pumps and heat exchangers.
With press fittings being more stable, better made and actually not introducing contaminants into a system this also makes it ideal for the use on pipework that is used for gas. Natural gas that is used in heating and hot water boilers and other combusting equipment is often fed by a gas pipe that has to be made of metal. Unlike other pipe systems in a central heating, hot water or potable water system the transportation of gas to an appliance has a requirement to be in metal, either copper or steel. With these restrictions in place for safety the use of a press gas fitting is even more beneficial. This is because there is a single closure of the connection mechanically which reduces the opportunity for error and it does not introduce any new substances into the pipework. The correct press fittings to be used on gas are Cupro-Fit M-Press Gas fittings. These are different to the standard M-profile gas fitting and have no requirement to meet WRAS certifications and contain a different o-ring. The O-ring is the material that all press fittings us to make the connection once the fitting profile is pressed. This o-ring is a different material and tested to a different standard when in use for gas. The specification for an O-ring is HNBR and the fitting would meet requirements to BSI KME and approved to EN-7. These fittings in turn would have to be used on EN copper tube. The o-ring is highly important to the connection and is denoted by the use of a yellow colour signifying gas. The normal M-Profile press fitting would use a black o-ring.
