Male thread steel fitting - 88.9 R3" 1509045017

Steel fitting for KAN-therm Steel installation

The GZ Steel fitting - 88.9 R3" is a reliable element of the KAN-therm Steel system, designed to create durable and safe connections in central heating, chilled water, process heat and industrial installations. Made of high-quality carbon steel with a galvanized coating to ensure corrosion resistance, it guarantees long-term operation even in harsh conditions. The fitting has a tapered BSPT-R (ISO 7-1 / EN 10226-1) external gas thread and a crimp socket, which facilitates installation and ensures a tight connection.

Construction and application

The fitting is designed to connect steel pipes with a nominal diameter of 3 inches (80 mm). Its construction based on carbon steel RSt 34-2 (material number 1.0034 according to DIN EN 10305-3) ensures mechanical strength and resistance to high pressure – up to 25 bar. The galvanized coating (Fe/Zn88) with a thickness of 8-15 µm provides additional protection against corrosion, and the chromium layer increases durability and aesthetics. The fitting is crimped with a controlled leakage function LBP (Leak Before Press), which allows for the detection of un-crimped connections before the installation is put into use – this is crucial for the safety and reliability of the system.

Advantages for professionals and users

• Fast installation: Pressing technology allows for quick and reliable connections without the need for welding or threading.
• Safety: The LBP function indicates un-crimped connections, minimizing the risk of leaks and failures.
• Durability: Made of carbon steel with a galvanized coating, it ensures corrosion resistance and long-term operation.
• Versatility: The fitting is compatible with other elements of the KAN-therm Steel system and can be used in various types of installations – from domestic to industrial.
• Pressure resistance: The ability to operate at pressures up to 25 bar makes the fitting suitable for applications requiring high reliability.
• Easy identification: Clear markings facilitate the identification of the size and type of fitting during installation and servicing.
• High quality workmanship: Guarantees precise fit and tight connections.
