Parker 8-12 Vtx-s Steel Male 45 Elbow 1/2 in Tube Od

Product Description

The PARKER 8-12 VTX-S is a steel male 45-degree elbow fitting designed for flared tube connections in high-pressure fluid and pneumatic systems. It features a 37-degree flare seat on the tube end and a male NPTF thread on the pipe end, creating a leak-resistant mechanical seal without the need for additional sealant tape on the tapered thread. Rated to 4000 psi maximum working pressure and a maximum working temperature of 500 degrees F, this fitting is built for demanding service in hydraulic, refrigeration, and fuel-line applications. HVAC technicians, plumbers, and fluid-power mechanics install this type of fitting as a directional change in rigid or semi-rigid tubing runs.

This fitting is suited for both residential and commercial installations where a 90-degree direction change is not practical and a 45-degree offset is required. Typical applications include hydraulic lines, fuel systems, refrigeration tubing, and general fluid-power plumbing. The Flare x MNPTF end configuration accepts a 1/2-inch OD flared tube on one end and threads directly into a 3/4-inch NPTF female port on the other. It meets ISO 8434-2, SAE J514, and SAE 070302 standards, making it appropriate for OEM equipment builds and field service repairs.

Key Features

• 37-degree flare seat conforms to SAE J514 and ISO 8434-2 flare fitting standards
• 4000 psi maximum dynamic working pressure for high-pressure line service
• Rated to 500 degrees F for compatibility with hot fluid and steam-adjacent systems
• NPTF thread standard provides a dry-seal connection that resists leakage at the thread interface
• Steel construction for strength and durability in industrial and mechanical environments
• Flare x MNPTF end configuration allows direct connection of flared tubing to NPT-ported components

Compatibility

Designed as a standard SAE J514 37-degree flare male elbow fitting with a 1/2-inch tube OD flare end and 3/4-inch MNPTF thread, suitable for use in hydraulic, fuel, refrigeration, and fluid-power systems requiring a 45-degree directional change at an NPTF-ported component or manifold.

Installation Notes

This fitting is typically installed by licensed HVAC technicians, hydraulic system mechanics, or journeyman plumbers working on fluid-power or refrigeration lines. Depressurize and isolate the system completely before disassembly or installation. The NPTF dry-seal thread is designed to seal without tape or compound, but verify compatibility with the mating port before assembly. Do not over-torque the flare nut, as excessive force can deform the flare seat and compromise the seal.
