Eaton 3500X2 Brass 90 Degree Female Elbow 1/8 Inch Fnptf

Product Description

The EATON 3500X2 is a 90-degree female elbow pipe fitting machined from brass for use in industrial and mechanical piping systems. It accepts 1/8-inch female NPT threads on both ports using the FNPTF (Female National Pipe Thread Fuel) thread standard, which provides a pressure-tight connection without requiring additional sealant on the threads. The fitting is rated for a maximum working pressure of 1200 psi and handles temperatures from -65 degrees F to 250 degrees F, making it suitable for a wide range of fluid and gas transfer applications. Plumbers, pipefitters, and HVAC technicians install this type of fitting where a 90-degree directional change is required in a small-diameter threaded line.

This fitting is used in residential and light commercial piping systems, pneumatic lines, hydraulic circuits, and fuel supply systems where 1/8-inch FNPTF threaded connections are specified. Its compact brass construction makes it a common choice in tight spaces where a hard 90-degree turn is needed in a low-to-moderate pressure line. It conforms to SAE 130238 standards, confirming dimensional and pressure-rating compliance for general industrial pipe fitting applications.

Key Features

• 90-degree female elbow configuration for directional changes in threaded pipe runs
• 1/8-inch FNPTF thread on both ports for a pressure-tight seal
• 1200 psi maximum working pressure rating
• Operating temperature range of -65 degrees F to 250 degrees F
• Brass construction for corrosion resistance in fluid and gas service
• Meets SAE 130238 standards

Compatibility

Designed as an OEM-style replacement or inline fitting for any piping system using 1/8-inch FNPTF threaded connections in industrial, HVAC, hydraulic, pneumatic, or fuel line applications.

Installation Notes

Installation is performed by a licensed plumber, pipefitter, or qualified HVAC technician. Shut off and depressurize the line completely before removing any existing fittings or making new connections. FNPTF threads are designed to seal on the threads themselves; consult the system manufacturer or applicable code for guidance on thread sealant use. Tighten to snug with appropriate wrenches — avoid over-torquing brass fittings, which can crack or deform the threads.
