What Are Pressed Components?;
Crimp fittings are special connectors used to join pipes (such as multilayer or copper) in water, heating or air conditioning networks.
Unlike traditional methods (such as welding, soldering, soldering or screwing), the connection here is achieved mechanically. Using a special tool (press), the fitting is permanently pressed onto the pipe. This mechanical squeezing activates special sealing rings (O-rings) located inside the fitting, creating a perfectly tight and extremely durable connection within seconds.
Main Advantages of Pressing Technology
The great success of this method is no accident. It offers clear advantages for both the craftsman and the end user.
- Installation Speed: A crimped connection is completed up to 50% faster than a welded or bolted connection.
- Security: No flame is required (as in welding), eliminating any risk of ignition or fire during installation.
- Reliability: The connection is permanent, stable and not affected by vibration or thermal expansion, as can happen with screwed fittings.
Innovation in Practice: the “Multi-Profile” components
An important step in the evolution of pressed systems is the creation of “multi-profile” components, such as the MULTIPRESS of IVAR.
What does this mean in practice?; It means that the fitting is designed to be correctly and safely crimped using different types of jaw (e.g., BE, B, TH, R, H, F, U).
This flexibility is critical for the professional installer. It allows him to use the press he already owns without being tied to a single, expensive profile. This simplifies the process, reduces equipment costs and ensures that the installation is done correctly, regardless of the tool.
Characteristics that guarantee waterproofness
The secret of a successful crimped connection lies in the details of component design. IVAR's leading MULTIPRESS systems incorporate specific technologies to eliminate multiple faults.
1. Double O-Ring design
The heart of the seal is the elastic ring (O-ring). Quality fittings use not one, but two EPDM peroxide O-rings. This creates a double safety barrier. Even under extreme pressure or temperature conditions, the existence of two sealing points provides maximum security. The EPDM material, moreover, guarantees enormous resistance to aging and high temperatures.
2. Visual Control Windows
One of the most common installation mistakes is not inserting the pipe fully into the fitting before crimping. To solve this, IVAR's modern MULTIPRESS fittings have special control “windows” in the bushing. Through these, the technician can see by eye that the pipe has reached the end. This simple visual aid ensures that the connection is always in the right position, preventing future leaks.
3. Material Quality and Certifications
The body of the component is equally important. IVAR's MULTIPRESSes are made of durable brass alloys (such as CW617N) that resist corrosion. For drinking water applications, they are also made of special lead-free alloys, such as Cuphin (CW724R), which ensure absolute water hygiene.
Of course, this quality must be confirmed by independent bodies. IVAR's MULTIPRESS fittings have certifications such as DVGW (Germany), WRAS (UK) and CSTBat/QB (France) which guarantee that the product has passed the most stringent tests of strength and suitability for drinking water.
Choosing the right connection fittings is a critical decision that affects the safety and longevity of the entire plumbing system. IVAR's MULTIPRESS press fitting technology, especially when incorporating innovations such as multi-profile compatibility and dual safety systems, now offers a proven fast, cost-effective and, above all, highly reliable solution for any modern building.
