Hydraulic crimp fittings permanently attach to hose ends in a crimper, forming a leak-free connection rated for the assembly's working pressure without reusable clamps or field-assembly tools. The right fitting is defined by its thread standard (JIC, NPT, ORB, SAE, or ORFS), its hose size and dash number, the body material, and the end configuration. Have an obsolete or unmarked fitting? send your specs for a cross-reference.

How to Choose a Hydraulic Crimp Fitting

Thread standard — JIC (37° flare), NPT (tapered pipe), ORB (O-ring boss), SAE, or ORFS (O-ring face seal); the fitting must match the port or coupling it threads into, since standards are not interchangeable.
Size / dash number — dash size sets both the hose ID and the thread size; a -08 fitting typically pairs with 1/2" hose, so confirm the dash on both the hose and the mating port.
Material — carbon steel for general high-pressure hydraulics, stainless steel for corrosion and washdown service, brass for lower-pressure or compatibility needs; match the material to the fluid and environment.
Configuration — straight, 45°, or 90° elbow, plus male or female ends; the angle and gender route the line and seal against the mating component.
Crimp spec — each fitting is engineered for a specific hose series and crimp diameter; use the die and crimp dimension the fitting manufacturer specifies for a rated connection.

Which Crimp Fitting Is Right for the Job?

Start from the thread standard at each end of the assembly. JIC and ORFS handle high-pressure hydraulic lines; NPT and ORB are common on pumps, valves, and manifolds. If the line needs to disconnect repeatedly, pair the fitting with Hydraulic Quick Couplers instead of a permanent crimp, or use Live Swivels where the hose must rotate under pressure. When you only need to convert one thread standard to another on a rigid port, an Adapters fitting may be the better choice than crimping. For non-hydraulic air, water, or low-pressure runs, see Industrial Fittings.

Complete the System

A crimp fitting is one end of a hose assembly. Pair it with the matching Hydraulic Hoses in the correct dash size and pressure rating, and confirm the mating ports with the rest of your Hydraulic Fittings. Add Hydraulic Quick Couplers or Enerpac Hydraulic Couplers where lines connect and disconnect, and cap open ends with Dust Caps and Plugs to keep contamination out during storage and shipping.

Cross-Referencing an Obsolete Crimp Fitting

If you have a fitting with no markings or a discontinued part number, we can identify the equivalent by thread standard, dash size, material, and crimp spec, then match it to current stock. With more than 1,000 crimp fittings on hand and cross-reference data built up since 1963, we can usually supply a working equivalent for fittings other suppliers have dropped. Send the dimensions, the hose series, or a photo and request a cross-reference.

Crimp Fittings – Frequently Asked Questions

How do I measure a crimp fitting to find the right size?

Identify the dash number, which sets both the hose ID and the thread size, then measure the thread diameter and pitch and confirm the seal type (flare, O-ring boss, or face seal). Match the dash and thread standard to both the hose and the mating port. If the part is unmarked, send the dimensions for identification.

What pressure can a crimp fitting handle?

A crimp fitting is rated as part of the complete hose assembly, so the working pressure is limited by the lowest-rated component in the hose, fitting, and crimp combination. Use the fitting on the hose series it is engineered for and crimp it to the specified die and diameter to reach the rated pressure.

What is the difference between a crimp fitting and a quick coupler?

A crimp fitting is permanently swaged onto a hose end for a fixed, leak-free connection, while a coupler lets you connect and disconnect a line by hand. If the line needs to come apart routinely, use Hydraulic Quick Couplers instead of, or in addition to, a crimp fitting.

Should I use a crimp fitting or an adapter?

Use a crimp fitting to terminate a hose end, and an adapter to convert one thread standard to another between rigid ports. When you only need to change thread standards on a port rather than build a hose, an Adapters fitting is usually the right part.

What thread standards do your crimp fittings come in?

We stock crimp fittings in JIC 37° flare, NPT tapered pipe, ORB O-ring boss, SAE, and ORFS O-ring face seal. The fitting must match the thread standard of the port or coupling it connects to, since these standards do not interchange.

What material should I choose for a crimp fitting?

Carbon steel covers most high-pressure hydraulic service, stainless steel suits corrosive or washdown environments, and brass works for lower-pressure or material-compatibility needs. Match the material to the fluid and the operating environment.

Do crimp fittings work with any hose?

No. Each crimp fitting is engineered for a specific hose series and crimp diameter, so the fitting, hose, and die must be a matched set. Confirm the hose series before ordering, and browse compatible Hydraulic Hoses in the same dash size.

Can you cross-reference an obsolete or unmarked crimp fitting?

Yes. Send the thread standard, dash size, material, and crimp spec, or a photo and the hose series, and we will identify a current equivalent from stock. To start, request a quote.
