- Reliable high-pressure connections up to 2 000 psi
- Secure leak-free JIC threads on both ends
- Durable carbon steel construction using 12L14 and 12L15 grades
- Straight rigid design keeps hydraulic lines aligned
- Meets SAE J514 standard for hydraulic fittings
Straight JIC Adapter for Hydraulic Lines
The Eaton 2027-20-20S connects two male JIC fittings sized at 1 1/4 in. It suits technicians assembling or repairing rigid hydraulic hose assemblies in industrial or mobile machinery. The carbon steel construction meets SAE J514 requirements for standard pressure service. Buyers needing a female port or a different thread standard cannot use this part.
Pressure Limit and Connection Constraints
The fitting is rated for 2,000 psi operating pressure in straight rigid configurations. Both ends use the same JIC male connection, so the adapter cannot join dissimilar thread types or sizes. No O-ring is included, meaning the seal relies solely on the JIC flare contact. Systems exceeding the stated pressure or requiring an elastomeric seal must select a different component.
Material Grade Determines Compatibility
The body is machined from 12L14 and 12L15 carbon steel grades as specified by the manufacturer. These free-machining steels dictate the adapter's corrosion resistance and fluid compatibility in service. Installers must verify that the material suits the hydraulic fluid and environment before fitting. Applications demanding stainless steel or alloy grades require an alternative part number.

Questions about this item
Should I choose the 1 1/4 in JIC straight adapter or a different size for my hydraulic system?
Select the 1 1/4 in size when both ports use a 1-5/8-12 thread; the fitting is rigid and rated for 2,000 psi, so it only suits systems matching that exact thread and pressure.
What does the 2,000 psi rating mean once the adapter is installed in a real machine?
It indicates the maximum working pressure the carbon steel fitting can handle continuously; operating above that risks leakage or failure at the JIC flare seal.
Which interface standard governs the 1-5/8-12 JIC connection and what does it cap in practice?
SAE J514 defines the thread form and flare geometry for this JIC size, limiting the connection to 2,000 psi with carbon steel construction.
