Is the Hose clamp, two-part with loose tongue, DIN 20039 A, cast iron suitable for pressures up to 16 bar with my hose and end fitting?

Yes . Hose clamp, two-part with loose tongue, DIN 20039 A, cast iron can be suitable for pressures up to 16 bar, but only if three conditions are met: 1. Correct clamp selection: choose the proper clamp index/size for your hose diameter (for large diameters use reinforced indices LU-SL-400 to LU-SL-988 as specified). 2. Compatible hose: the hose itself must be rated for â¥16 bar working pressure and compatible with the clamp geometry (tail/end fitting style) and media. 3. Proper end fitting and installation: the hose end fitting (tail) must match the clamp design (no safety flange), be correctly assembled, and the clamp must be installed per manufacturer torque/assembly instructions so the pressure tongues and two-part cast iron body fully engage. Material and construction (galvanized ductile cast iron, DIN 20039 A, separate pressure tongues) allow a working pressure up to 16 bar when the above conditions are satisfied. If any of the three conditions are not met, the assembly may not be safe at 16 bar . verify hose and fitting ratings and follow installation guidelines or consult the manufacturer for application-specific approval.

Can the Hose clamp, two-part with loose tongue, DIN 20039 A, cast iron be used on a 50 mm hose with compatible end fittings for 16 bar?

Yes - Hose clamp, two-part with loose tongue, DIN 20039 A, cast iron can be used on a 50 mm hose with compatible end fittings for 16 bar, provided these conditions are met: correct clamp size for 50 mm hose, proper installation following DIN 20039 A guidelines, use of compatible hose and end fittings rated for 16 bar, and (if applicable) selection of reinforced indices LU-SL-400 to LU-SL-988 for larger diameters. Material (galvanized ductile cast iron) and separate pressure tongues are suitable; ensure torque and assembly are correct to achieve the specified working pressure.

Can the Hose clamp, two-part with loose tongue, DIN 20039 A, cast iron be used with reinforced LU-SL-988 for large-diameter hoses?

Yes. Hose clamp, two-part with loose tongue, DIN 20039 A, cast iron Format can be used with reinforced LU-SL-988 for large-diameter hoses, provided several conditions are met: - Compatibility: LU-SL-988 is part of the reinforced index range (LU-SL-400 to LU-SL-988) specifically intended for large diameters, so the clampâs design and reinforcement suit large hose sizes. - Construction: The clamp is manufactured to DIN 20039 A with separate pressure tongues and made from galvanized ductile cast iron (yellow passivated, Cr6âfree), matching the described material and construction suitable for heavyâduty applications. - Pressure rating: When correctly installed with an appropriately selected hose and compatible end fitting, the assembly can achieve working pressures up to 16 bar. Ensure the hose and fittings are rated for the same or higher pressure. - Installation: Proper installation is critical. correct seating of pressure tongues, torque specification, and use on the hose âtailâ without a safety flange must follow manufacturer instructions to ensure sealing and load distribution. - Verification: Confirm dimensional match (hose outer diameter vs. clamp range), and verify the hose type (reinforced LU-SL-988) is compatible with pressure tongues and cast iron contact (no galvanic/corrosion issues in the application environment). Conclusion: YesâHose clamp, two-part with loose tongue, DIN 20039 A, cast iron Format is suitable for use with reinforced LU-SL-988 for largeâdiameter hoses if the clamp size matches the hose, installation is correct, and hose/fittings meet the required pressure and compatibility specifications.
