DKJ 45° (C95) Fittings

Hose crimp fitting in 45° elbow version with UNF female thread

JIC 45° (UNF) elbow fittings have a female thread (GW) and a 74-degree seat.  In Poland, these fittings are often found under the designation C95 = DKJ45. They are commonly called American fittings ( due to the UNF thread and the cone type ). This type is found in modern agricultural, construction, and forestry equipment - of Western production. Our offer also includes right-angle (90-degree) elbow fittings made of galvanized free-cutting steel. We also offer air conditioning fittings at a 45-degree angle.

What is a DKJ45° UNF hose fitting?

The DKJ45 UNF fitting is a hose fitting used for crimping hydraulic hoses in high-pressure systems. It features a UNF (Unified National Fine) thread and a 74° conical end, which guarantees the tightness and durability of connections. Thanks to the 45° bend, this fitting allows for easy routing of lines in places where angled connections are required. What is it for? The DKJ45 UNF fitting is designed to create tight and durable connections in hydraulic systems. Thanks to its design, it is used in: crimping hydraulic hoses in systems with high working pressure. Facilitating the routing of hoses in hard-to-reach places or where the lines must be routed at a 45° angle. Reducing mechanical stresses in systems, which increases the durability of the installation.

Where are DKJ45° elbow fittings used?

DKJ45 UNF fittings are widely used in various industries, such as: Power hydraulics – industrial and mobile installations. Forestry - various types of forestry machinery. Construction – construction machinery, cranes, loaders. Agriculture – tractors, combines, and other agricultural machinery. Automotive – power steering systems and hydraulic brakes.

What other versions of the DKJ45 crimp fitting are available ?

In addition to DKJ45 UNF fittings, our offer also includes: DKJ90 UNF fittings – designed for connections at a 90° angle. Ideal for systems where lines must be routed along sharp bends in the installation. Check: DKJ90 UNF fittings. Straight DKJ UNF fittings – universal fittings for straight hydraulic connections. They are the most frequently chosen solution for standard installations. Check: DKJ UNF fittings.

DKJ 45° UNF (C95) hydraulic elbow fittings, JIC crimps for hoses

Safe transmission of working fluids in tight working spaces of machines requires the use of profiled connection elements. DKJ 45° UNF fittings belonging to the C95 group in the HYDRON system are professional crimps for hydraulic hoses with a swivel nut and American fine-pitch inch thread UNF or UN. The 45-degree bent design significantly facilitates the routing of pressure lines, preventing them from kinking and reducing fatigue stresses in the circuit. The 74-degree seat seal compliant with the JIC standard guarantees a metal-to-metal leak-tight connection. At the HYDRON online store, we offer a selection of DKJ 45° C95 crimps in many sizes.

Application and technical characteristics of DKJ 45° (C95) crimps

The DKJ 45° elbow fitting is used in hydraulic installations of agricultural, construction, forestry, and transport machinery. The 45° profiled bend allows for changing the direction of the hose routing in places where using a straight fitting could cause unfavorable hose positioning.

• Connecting hoses to cylinders and distributors: facilitates hose routing in areas with limited installation space.
• Limiting excessive hose bending: the 45° bend allows for proper hose routing at the connection point. For connections requiring a greater change in direction, there are also available DKJ 90° C92 fittings.
• Hydraulic hose construction: the appropriate fitting variant should be selected for the diameter, hose design, and required crimping technology.
• JIC connection: the swivel nut facilitates the installation of the fitting on the appropriate connection with a UNF or UN thread.

Standard JIC 37° / 74°

DKJ fittings use a solution characteristic of JIC connections. The sealing surface has a 37° angle relative to the axis, which corresponds to a full 74° cone angle. The connection is achieved by appropriately pressing the mating metal surfaces.

When selecting a fitting, pay attention not only to the hose diameter but also to the thread size and pitch. Depending on the size of the connection, UNF and UN threads appear in this group.

Frequently Asked Questions (FAQ)

What is the cone angle in DKJ 45° fittings from the C95 group?

DKJ fittings use a JIC connection with a sealing surface of 37° relative to the axis, which corresponds to a full 74° cone angle.

Do C95 fittings require O-ring seals?

The JIC connection uses mating metal conical surfaces and does not require an O-ring on the cone's sealing surface.

How to choose the right DKJ 45° fitting?

You should check the diameter and construction of the hose, the size and pitch of the UNF or UN thread, as well as the required routing angle of the line.
