Hydraulic JIC Fittings Features

JIC Hydraulic fittings Meet the standards of the SAE J514 and MIL-DTL-18866 and are flared fittings machined with a 37-degree flared seating surface. JIC fittings have different sizes, and types with materials of carbon steel, brass, and stainless steel, contact Topa to get the catalog. Female and male threads of the same size are screwed together to form a complete metal-to-metal seal. Suitable for high and low temperatures as they do not require the use of rubber ring seals.JIC hydraulic fittings are the most common end connection for hydraulic hose assemblies. They are widely used in fuel transfer and fluid power applications. Materials commonly used in the manufacture of JIC hydraulic fittings include carbon steel, stainless steel and brass.

Leak Prevention

The robust design of the adjustable port stud features a longer locknut, reducing the risk of washer damage and preventing leaks. This feature ensures a virtually mistake-proof assembly process, improving internal efficiencies and significantly reducing rework costs that are often caused by backup washer damage, which is commonly seen with traditional SAE adjustable port ends.

Durable and Galling-Resistant

The stainless steel nuts used in JIC fittings are coated to prevent galling, a common issue in high-stress hydraulic systems. This anti-galling feature ensures that the fittings remain secure and intact under pressure, minimizing wear and ensuring long-term reliability in demanding conditions.

Global Compatibility

JIC hydraulic fittings are designed to be easily adaptable to both inch and metric tubes, as well as hoses. This versatility ensures that they are widely accepted and used across different industries and regions worldwide, making them an ideal solution for international applications and diverse hydraulic systems.

Comprehensive Port End Options

Our JIC fittings offer a vast selection of port end options, providing flexibility in matching your system’s requirements. Available configurations include SAE Straight Thread O-ring Boss (ORB), NPTF, BSPP-ED, BSPP-O-ring Retaining Ring (ORR), BSPP, BSPT, ISO 6149, and various metric options like Metric-O-ring Retaining Ring (ORR) and Metric-ED, ensuring compatibility with numerous connection types and international standards.

High-Pressure Capability

Available in steel, stainless steel, and brass, JIC fittings are designed to handle high-pressure environments, with working pressures reaching up to 7,500 psi. Sizes range from 1/8” to 2 ½”, offering flexibility for a wide range of hydraulic applications. These fittings are built to withstand extreme conditions, ensuring both high performance and longevity in various industries.

Superior Corrosion Resistance

Independent testing has shown that these fittings can last up to 96 hours before developing white rust, providing outstanding durability in corrosive environments. This enhanced corrosion resistance helps minimize downtime, extend equipment life and reduce warranty costs, giving customers a competitive advantage.

All You Need to Know About Hydraulic JIC Fittings

Working Principle

JIC hydraulic fittings operate on the principle of creating a secure, high-pressure connection using a 37° flare and straight thread design. When the fitting is installed, the 37° flare makes contact with the mating surface, forming a tight seal that prevents fluid leaks. The threads provide mechanical stability, ensuring the fitting stays firmly in place under high-pressure conditions. These fittings are designed to handle high-flow, high-pressure hydraulic systems, and the 37° flare ensures that the fitting can withstand vibration, thermal expansion, and other stress factors commonly found in industrial environments.

Materials

JIC hydraulic fittings are made from high-quality materials designed to withstand demanding hydraulic systems and harsh environments. The common materials used are:

Steel – Provides excellent strength and durability, making it ideal for high-pressure applications. Steel fittings are often coated with corrosion-resistant layers for additional protection.

Stainless Steel – Offers superior corrosion resistance, making it perfect for use in environments exposed to moisture, chemicals, and extreme temperatures. Stainless steel fittings are often preferred in industries like food processing, pharmaceuticals, and marine applications.

Brass – Known for its ease of machining and resistance to corrosion, brass fittings are ideal for moderate-pressure systems and environments where strength requirements are lower compared to steel or stainless steel.

Structures

The typical JIC fitting features the following key structural components:

37° Flare – JIC fittings are distinguished by their 37° flare angle, which ensures a tight, leak-free seal when mated with the corresponding tube or hose. This flare angle creates a mechanical seal that can handle high-pressure conditions.

Straight Threads – JIC fittings have straight threads, which provide a secure connection without the need for additional seals or gaskets. These threads ensure the fitting stays in place without leaking under pressure.

Locknut and Port Stud (for Adjustable Ports) – The locknut helps secure the fitting in place, while the port stud holds the fitting to the port. Some designs feature a longer locknut for improved stability and reduced potential for washer damage.

Hydraulic JIC Fittings Manufacturing Process

At Topa, we employ advanced CNC machining to produce our Hydraulic JIC fittings with precision. The manufacturing process includes raw material selection, CNC turning and milling, threading, and final quality inspection. Each fitting undergoes stringent testing for dimensional accuracy and pressure tolerance. Once finished, the fittings are carefully cleaned and prepared for shipping.

Material Selection

Depending on the application, materials such as steel, stainless steel, or brass are chosen. The raw materials are then cut to the required lengths and prepared for machining.

CNC Machining

The prepared material is then fed into CNC machines, which precisely cut and shape the fittings to the desired dimensions.

Flare Formation

This step involves the creation of a 37° flare at the end of the fitting, which is essential for sealing the fitting to hydraulic hoses or tubes.

Surface Treatment

Common treatments include galvanizing (zinc coating) or applying plating for steel fittings. Stainless steel fittings may receive coatings to prevent galling.

Assembly

Once the fittings are coated and treated, they are assembled with additional components if necessary, such as O-rings, seals, or locknuts.

Packaging and Shipping

Custom packaging options are available for clients who require branded or specific packaging solutions.

Hydraulic JIC Fitting Quality Control

At Topa, our quality control (QC) process is rigorous and comprehensive to ensure that every JIC hydraulic fitting meets the highest standards of precision, durability, and reliability. Each fitting undergoes a series of checks throughout the manufacturing process to guarantee flawless performance in demanding hydraulic systems.
