35 mm coupling - thin-walled galvanized carbon steel crimped PC5270 0350000

Application and Characteristics of the Crimped Coupling

This component is designed for the permanent joining of steel pipes in installations where tightness and pressure resistance are required. Thanks to its crimped design, installation is carried out without the need for welding or threading, significantly accelerating on-site work and eliminating the risk of material damage due to high temperatures. The 35 mm coupling is intended for systems using pipes with an outer diameter of 35 mm, ensuring a direct straight-line connection between two pipe sections.

The material of manufacture is carbon (alloyed) steel, which has undergone galvanic zinc coating. This surface treatment protects against corrosion under standard conditions, which is crucial for long-term operation in water or heating installations. It is worth noting that the product features a stop flange – this element facilitates precise pipe centering during installation and prevents shifting during crimping.

Key Structural Features and Operating Conditions

The coupling has a monolithic (one-piece) construction, resulting in fewer potential failure points compared to multi-component solutions. The absence of seals within the coupling body means that tightness is achieved through mechanical deformation of the pipe and fitting material, requiring the use of a dedicated crimping tool.

In practice, this means the component withstands a maximum working pressure of up to 16 bar at 20°C, making it suitable for most standard low-pressure installations. The total length of the fitting is 62 mm, and the outer diameter on both sides is 35 mm. It is intended exclusively for steel pipes and does not serve as a reducer or air vent – its function is simple linear connection. Both connection sides feature a galvanic/electrolytic zinc layer, ensuring uniform anti-corrosion protection along the entire length of the component.

These data confirm that the coupling is a simple yet robust element – its dimensions (62 mm length with a 35 mm diameter) and material (alloyed steel) are selected to withstand typical loads in building installations without additional rubber or EPDM seals.

Installation and System Compatibility

During installation, it should be noted that the product does not carry UL, FM, or LPCB certifications, meaning its application should be limited to installations not covered by these specific standards or where other local approvals are required. The absence of ULC certification also indicates non-approval for specific North American markets in the context of fire protection.

For the installer, this means the necessity of using a crimping jaw head specifically dedicated to galvanized steel with a 35 mm diameter. The connection is permanent and does not require periodic tightening or seal replacement (due to the absence of seals). This is a "install once and forget" solution, provided the crimping is performed correctly according to the tool manufacturer's instructions. The product is not intended for chemically aggressive media or applications requiring special EPDM rubber seals – in this case, the sealing function is performed by the metal itself after plastic deformation.
