Can Carbon Steel Short Sleeve for Low-Pressure Hose Crimping, Type H be used with NiTO and quick coupling ends on hoses up to 30 bar?

Yes — Carbon Steel Short Sleeve for Low-Pressure Hose Crimping, Type H can be used with NiTO and quick coupling ends on hoses up to ~30 bar, provided these conditions are met: - The hose is a low-pressure type and the operating pressure does not exceed approximately 30 bar (actual limit may vary with hose diameter). - The hose structure is soft enough to be secured by a crimp sleeve (typical: rubber with textile reinforcement, PVC; possible for steel-braided PZ-type hoses if construction allows). - The internal diameter of the sleeve matches the hose external diameter precisely. - The sleeve’s front hole diameter corresponds exactly to the chosen NiTO or quick coupling end. Manufactured from galvanized carbon steel, the sleeve offers adequate strength and corrosion resistance when the above matching criteria are fulfilled.

Can Carbon Steel Short Sleeve for Low-Pressure Hose Crimping, Type H be used on hoses reinforced with steel braid (e.g., PZ type) and what are the limits?

Can Carbon Steel Short Sleeve for Low-Pressure Hose Crimping, Type H be used on hoses reinforced with steel braid (e.g., PZ type) and what are the limits? Yes — Carbon Steel Short Sleeve for Low-Pressure Hose Crimping, Type H can be used on hoses reinforced with steel braid (PZ type), but with important limits. It is intended for low-pressure applications up to approximately 30 bar (actual maximum depends on hose diameter). The sleeve works best when the hose structure is soft enough to deform under the crimp and form a secure grip, so rubber hoses with textile reinforcement and PVC hoses are ideal. Steel-braided hoses may be crimpable only if their braid and cover allow sufficient compression; excessively stiff or heavily braided constructions can prevent a reliable crimp. For safe use: ensure the sleeve’s internal diameter exactly matches the hose external diameter, and the front hole diameter matches the chosen fitting (NiTO or quick coupling). Verify the hose’s rated working pressure, braid density/stiffness, and perform pull/pressure tests after crimping. If the hose’s braid makes proper deformation impossible or the working pressure exceeds ~30 bar, use a dedicated crimping system/fitting designed for steel-braided hoses.

Material	CS – steel (cast iron)

The H-type crimping sleeve is a reliable solution for securing hose ends without the need for a locking mechanism, ensuring a safe and durable connection. It is compatible with NiTO ends as well as quick coupling ends, offering versatility across different applications. Designed for low-pressure hoses up to approximately 30 bar, depending on the hose diameter, the sleeve can be used with a wide range of materials, provided the hose structure is soft enough for this type of clamp. Ideal for rubber hoses with textile reinforcement and PVC hoses, it also allows the possibility of crimping hoses reinforced with steel braid, such as PZ type hoses. For optimal performance, the internal diameter of the sleeve must be carefully matched to the external diameter of the hose, while the front hole diameter should correspond precisely to the chosen end fitting. Manufactured from high-quality galvanized carbon steel, the sleeve guarantees strength, corrosion resistance, and long-lasting reliability, making it a practical and cost-effective choice for industries requiring secure hose connections.
