Vaša ruka već zna razliku: JIC muški spoj glatko se uvlači u JIC ženski okretni zglob i sjedala s metalno-metalnim proširenjem od 37°. Probajte isti muški priključak u NPT priključak, i on se zalijepi, propušta ili oštećuje navoje. Taj kratki test pokazuje zašto su JIC hidraulički spojevi popu...

Prisiljavanjem malo više stvara se veza koja izgleda dobro, ali curi čim sustav dosegne radni tlak. U servisu na terenu, neusklađeni navoji hidrauličkog spoja uzrokuju curenje, ogoljene otv...
View MoreA hydraulic hose bursts on an excavator arm at mid-morning. The spare fitting in the toolbox looks exactly like the damaged one, but it will not thread on. Identifying hydraulic fittings correctly is what separates a 20-minute repair from a half-day hunt for the right adapter. Most hydra...
View MoreA standard hose fitting is a critical connector used in hydraulic systems to securely join hoses with other components such as pumps, valves, and cylinders. These fittings ensure a tight seal and efficient fluid transmission under high pressure, often exceeding 3,000 PSI . A reliable fitting can significantly reduce leakage risks and improve system efficiency by up to 15% .
Standard hose fittings are widely used across industries including construction, agriculture, and manufacturing, where durability and reliability are essential.
Our fittings are available in carbon steel and stainless steel . Carbon steel is suitable for general applications, while stainless steel is ideal for environments requiring high corrosion resistance, such as marine or chemical industries.
We use trivalent zinc plating (Cr3, chrome-free) with silver and yellow finishes. This eco-friendly coating enhances corrosion resistance while meeting environmental standards.
Our fittings pass a salt spray test of over 72 hours , and can reach up to 200 hours upon request, ensuring long-term durability in harsh environments.
Each product is protected with plastic caps and packed in carbon boxes to prevent damage during transportation and storage.
| Material | Corrosion Resistance | Application |
|---|---|---|
| Carbon Steel | Medium | General hydraulic systems |
| Stainless Steel | High | Marine and chemical industries |
