Structure and Materials

The 43 Series hydraulic crimp fitting consists of two primary parts — the fitting body and the ferrule. The fitting body forms the connection interface with the hydraulic port, while the ferrule is crimped onto the hose to create a secure and permanent connection.

Materials

Standard models are manufactured from high-quality carbon steel, offering excellent strength and pressure resistance. The surface is typically treated with zinc plating or zinc-nickel alloy coating to improve corrosion resistance. For harsh or highly corrosive environments, stainless steel versions are also available, providing extended service life and reliability in marine or chemical applications.

Surface Treatment

Most fittings feature a Cr6-free zinc plating for environmental compliance and improved corrosion protection. Depending on the coating type, salt spray resistance can range from 72 hours up to 1000 hours, ensuring reliable performance even in demanding outdoor or industrial environments.

Sealing Methods

Multiple sealing options are available to suit different hydraulic systems and media. These include O-ring seals, 37° cone seals, and flat-face seals, each designed to provide leak-free performance under high pressure and vibration.

Applications

43 Series hydraulic hose crimp fittings are engineered for versatility and durability, making them suitable for a wide range of demanding applications. From construction and agriculture to industrial hydraulics, these fittings provide secure, leak-free connections that maintain peak performance even under high pressure and continuous operation. Whether powering heavy machinery or precision equipment, they ensure reliable hydraulic performance in every environment.

Construction Machinery

Widely used in heavy-duty equipment such as excavators, wheel loaders, and bulldozers, where hydraulic systems must withstand extreme pressures, frequent motion, and harsh environmental conditions.

Agricultural Machinery

Ideal for equipment like tractors and combine harvesters, which require durable and leak-free hydraulic connections to operate implements, lifting arms, and other hydraulic-driven attachments efficiently.

Industrial Hydraulic Systems

Commonly installed in hydraulic presses, stamping machines, and other industrial machinery, where precision and reliability are critical to maintaining production efficiency and safety.

Performance Features

High Reliability

The crimp-style connection design is engineered to withstand high operating pressures and repeated pressure surges, making it ideal for demanding hydraulic applications. The robust construction ensures long-term durability even in heavy-duty environments.

Leak Resistance

Precision-machined sealing surfaces combined with high-quality, compatible sealing elements deliver a secure and leak-free connection, reducing downtime and maintenance costs.

High Assembly Efficiency

Designed for use with compatible crimping machines, the fittings enable fast and consistent assembly, improving productivity in both OEM production lines and maintenance workshops.

Multiple Port Options

Available in a wide range of thread and flange configurations — including BSP, NPT, JIC, ORFS, metric threads, and SAE flanges — to meet the standards and requirements of different global markets.

Strong Interchangeability

In most cases, 43 Series fittings can be interchanged with equivalent products from other major brands, making them a flexible choice for replacement and system upgrades without extensive modifications.

FAQ

What type of hoses are compatible with the 43 series hydraulic crimp fitting?

The 43 Series is designed for use with one-wire braided (SAE 100R1AT) and two-wire braided (SAE 100R2AT) hydraulic hoses. Certain models are also compatible with SAE 100R16 and 100R17 hoses.

What pressure ratings can these fittings handle?

The working pressure depends on the hose size and type, but 43 Series fittings can handle pressures up to 6000 psi (about 420 bar) when paired with the appropriate hose. Always refer to the manufacturer’s pressure ratings.

Are these fittings interchangeable with other brands?

In most cases, yes. The 43 Series is dimensionally compatible with similar products from other major brands, but it’s always best to confirm crimp specifications before mixing brands.

What materials are available?

Standard fittings are made from carbon steel with zinc or zinc-nickel plating. Stainless steel versions are available for applications in corrosive or marine environments.

What thread and connection types are offered?

The 43 Series is available in BSP, NPT, JIC, ORFS, metric, and SAE flange connections, covering a wide range of global standards.

How do I maintain these fittings for long service life?

Keep fittings clean before installation, follow correct crimp dimensions, inspect connections regularly for leaks or damage, and replace them based on service intervals suited to your application.
