3/8 Hose x 3/8 JIC 37 Degree Female Swivel Hydraulic Hose Crimp

In this review the 3/8 Hose x 3/8 JIC 37 Degree Female Swivel Hydraulic Hose Crimp Fittings are evaluated for technicians and hobbyists who need a robust crimp fitting for single wire hydraulic hose. The bottom line: these fittings are valuable when a permanent, leakresistant connection is required in fluid power systems because they crimp to a 3/8' I.D. hose and provide a reliable 3/8' female JIC 37 degree swivel end. The review focuses on durability, compatibility with common hydraulic fluids, and temperature resilience.

Key Features

• Crimp compatibility: Designed specifically to crimp with 3/8' I.D. single wire hydraulic hose, ensuring a secure, permanent attachment when used with a proper crimping machine.
• JIC swivel end: The 3/8' female JIC 37 degree swivel end allows straightforward connection to JIC male fittings and helps align components without twisting the hose.
• Material strength: Made from carbon steel to improve durability and resist heat, providing extended service life in demanding environments.
• Wide temperature range: Rated to withstand temperatures from -65F to 500F, suitable for many industrial and mobile hydraulic applications.
• Fluid compatibility: Suitable for petroleum-based fluids, gasoline, fuel, and lubricating oils, making it versatile for general hydraulic systems.
• Straight fitting shape: The straight configuration simplifies routing and keeps hose runs compact where a simple inline connection is needed.

Who It's For

These crimp fittings are best for professional mechanics, hydraulic technicians, and experienced DIYers who have access to a crimping machine and work on pumps, valves, cylinders, or other hydraulic components. The fittings suit shops and maintenance crews that need permanent, leak-resistant hose connections for petroleum-based fluids and common hydraulic systems.

Users who should look elsewhere include those who need reusable or quick-disconnect fittings, those working with specialized non-petroleum fluids not listed here, or beginners without crimping equipment, since these are permanent crimp fittings that require proper tooling and skill.

Pros & Cons

Pros

• Durable carbon steel construction improves resistance to wear and high temperatures.
• Designed for a precise 3/8' I.D. hose match and 3/8' female JIC 37 degree swivel connection, reducing leak risk when crimped correctly.
• Versatile compatibility with common hydraulic and petroleum-based fluids used in many industrial applications.
• Straight fitting shape makes routing and installation in tight runs simpler.

Cons

• Permanent crimp design requires a crimping machine and is not user-removable, so replacements demand re-crimping or hose reassembly.
• Limited to applications compatible with carbon steel and the listed fluid types; not specified for specialty fluids.

Our Verdict

The 3/8 Hose x 3/8 JIC 37 Degree Female Swivel Hydraulic Hose Crimp Fittings are a practical choice for professionals and well-equipped DIYers who need permanent, heat-resistant connections for common hydraulic fluids. They deliver good value where a robust, crimped joint and a JIC swivel interface are required, but they are not suitable for users who need reusable or tool-free fittings.

Frequently Asked Questions

Can these fittings be reused after crimping?
Answer. These are permanent crimp fittings and are not designed for reuse; removal typically requires cutting the hose and re-crimping a new fitting.

What fluids are safe to use with these fittings?
Answer. They are suitable for petroleum-based fluids, gasoline, fuel, and common lubricating oils as indicated by the specification.

What tooling is required to install them?
Answer. A hydraulic hose crimping machine sized for 3/8' I.D. hose is required to attach these permanent fittings correctly.
