Hydraulic Adapter Fitting Types

Two Types of Hydraulic adapter fittings, one type is JIS B8363 and BS5200 hydraulic hose adaptor fitting, another type is Pipe fittings such as Male or Female NPT adapter, BSPT adapter, Plug and caps. This hydraulic connector is from hydraulic pump or hydraulic motor to various types of hydraulic tube fitting ends such as DIN, JIC, ORFS, you often can find pipe fittings and port adapter thread types including: NPT, NPTF, BSPT, BSPP, SAE UN/UNF, and Metric.

Hydraulic Adapter Fittings Catalog

Our ISO SAE standard of hydraulic adapter fitting is the analogues of Parker, Eaton, Gates’s company standard, but the same function to connect port fittings. For wholesale, distributor, trader of hydraulic parts in the worldwide such as Russia, UK, Australia, Canada, USA etc, we are your reliable partner.

Standards of Hydraulic Adapter Fittings

In the world of hydraulics, adapter fittings play a vital role in connecting hydraulic pumps or motors to numerous hydraulic tube fitting ends. Predominantly, you'll find two kinds of hydraulic adapter fittings. First is the hydraulic hose adaptor fitting compliant with JIS B8363 and BS5200 standards, and second is the variety of pipe fittings which can be Male or Female NPT adapter, BSPT adapter, plug and caps.

These adapter fittings are not just associated with one standard but are spread over numerous national and international standards like ISO, SAE, DIN, BSPP, NPTF, and JIS to cater to a broad range of industry requirements. For instance, ISO 8434-6 and BS 5200 standards govern the 60-degree cone connectors with BSPP threads, while the JIS B8363 standard regulates 60-degree cone hose adapters.

Connection standards like DIN 3852-1, ISO 9974-1, and SAE J514 also contribute significantly to the hydraulic adapter fittings' regulatory landscape. This array of standards ensures optimal performance and safety across all hydraulic systems.

Our collection of ISO SAE hydraulic adapter fittings parallels the standards established by prominent hydraulics companies like Parker, Eaton, and Gates. As a trusted partner for wholesalers, distributors, and hydraulic parts traders across the globe, we strive to provide top-notch products that meet the high standards of the hydraulic industry.
