In demanding hydraulic environments, not all fittings are built the same. When performance, vibration resistance, and leak-free connections matter most, 37 Degree JIC/AN fittings stand out as one of the most trusted solutions in the United States.
From heavy-duty equipment to aerospace applications, these fittings are engineered for precision. For businesses seeking reliable supply and consistent quality, Gear House Hydraulics delivers top-tier JIC/AN fittings designed to perform under pressure.
What Are 37 Degree JIC/AN Fittings?
37° JIC (Joint Industry Council) and AN (Army-Navy) fittings use a 37-degree flare seating surface to create a strong metal-to-metal seal. Unlike other thread-based sealing methods, these fittings rely on flare alignment, ensuring a tight and reusable connection.
They are especially popular in the USA due to their standardization and compatibility across a wide range of hydraulic systems.
Why 37° JIC/AN Fittings Are Preferred
These fittings are widely used because they offer a balance of strength, reliability, and ease of maintenance.
Key Advantages:
- Leak-resistant metal-to-metal seal
- Excellent vibration resistance
- Reusable without compromising performance
- High-pressure capability
- Easy inspection and maintenance
This makes them ideal for industries where downtime is costly and performance is critical.
JIC vs AN Fittings: Is There a Difference?
While often used interchangeably, there are slight distinctions:
- JIC Fittings – Common in commercial and industrial hydraulic systems
- AN Fittings – Designed for military and aerospace applications with tighter tolerances
Both share the same 37° flare design, making them broadly compatible in many applications.
