What is the maximum working pressure of the Three-part cast iron hose clamp with catches, DIN 20039 B when properly installed?

The maximum working pressure of the Three-part cast iron hose clamp with catches, DIN 20039 B, when properly installed and used with a correctly matched hose and fitting, is up to 25 bar.

How do the separate pressure inserts ("tongues") in the Three-part cast iron hose clamp with catches, DIN 20039 B improve long-term hose sealing and stability?

The separate pressure inserts (“tongues”) in the Three-part cast iron hose clamp with catches, DIN 20039 B improve long-term hose sealing and stability by distributing and maintaining clamping force precisely where it’s needed. Key benefits: - Localized, uniform pressure: Each tongue bears directly on the hose circumference, evening out load and preventing high-pressure points that can cut or deform the hose. - Enhanced sealing over time: By compensating for material relaxation, thermal cycling and vibrations, the tongues preserve constant radial compression, maintaining a tight seal and reducing leaks. - Increased mechanical stability: The segmented design resists loosening and creep better than a single-band clamp, keeping the hose end anchored under dynamic loads up to the clamp’s rated pressure. - Protection of hose material: Smooth, controlled contact reduces abrasion and extrusion of the hose lip into fittings, extending hose life. - Easy assembly and reliable performance: Individually formed tongues conform to hose profiles and work with the flange hooks to secure ends reliably, minimizing maintenance and downtime. Together these effects ensure the clamp sustains effective sealing and structural integrity in demanding industrial applications.
