Parker 249IFHD-5-4 Brass Inverted Male Elbow 5/16 in

Product Description

The PARKER 249IFHD-5-4 is a 90-degree inverted male elbow fitting machined from brass, designed to connect flared tubing to a male NPTF port. It accepts 5/16-inch tube OD on the flare end and threads into a 1/4-18 NPTF female port on the mating end. Rated to 1200 psi maximum working pressure and up to 250 degrees F, this fitting suits demanding fluid and refrigerant line routing where a right-angle transition from tubing to a threaded component is required. Licensed HVAC technicians and refrigeration mechanics are the primary installers, though it also sees use in hydraulic and pneumatic plumbing applications.

This elbow is appropriate for residential and light commercial installations where 5/16-inch flared tubing must terminate at a 90-degree angle into an NPTF-ported component. Typical scenarios include refrigerant line sets, hydraulic control circuits, and compressed-air distribution where a compact directional change is needed without fabricating a bent tube section. It meets SAE J51 standards and carries UL Listing, making it suitable for use in systems where listed components are required by code or specification.

Key Features

• 90-degree geometry routes 5/16-inch flared tubing into tight spaces without tube bending
• Brass construction provides corrosion resistance and reliable sealing at the flare interface
• 1200 psi maximum working pressure suits high-pressure fluid and refrigerant systems
• 250 degrees F maximum working temperature handles typical HVAC and refrigeration service conditions
• SAE J51 compliant and UL Listed for use in code-required applications
• NPTF thread standard provides a dry-seal connection without relying solely on thread sealant

Compatibility

Designed for use with 5/16-inch OD flared tubing and components featuring a 1/4-18 NPTF female port. Suitable for refrigerant, hydraulic, and pneumatic lines where SAE J51 flare fittings are specified.

Installation Notes

Installation is performed by licensed HVAC technicians, refrigeration mechanics, or qualified pipefitters. De-pressurize and recover any refrigerant or fluid from the system before removing or installing fittings. Ensure the flare is formed correctly to SAE J51 specifications before tightening to avoid leaks at the flare seat. Apply an appropriate thread sealant to the NPTF threads per manufacturer and local code guidance, and do not overtighten, as brass fittings can crack under excessive torque.
