Parker 10327 Steel 90 Elbow Fitting 5/16 in Od 1/8-27 Nptf

Product Description

The PARKER 10327 is a steel 90-degree flared tube elbow fitting designed for high-pressure fluid and gas line connections in industrial and mechanical systems. It features a 37-degree flare seat on the tube end and a 1/8-27 NPTF male thread on the port end, providing a leak-resistant metal-to-metal seal without the need for thread sealant tape on the NPTF side. Rated to 6000 psi maximum working pressure and 500 degrees F, this fitting is built for demanding service conditions. It is installed by licensed plumbers, pipefitters, and fluid power technicians working on hydraulic, pneumatic, or refrigeration line assemblies.

This fitting is suited for applications requiring a 90-degree directional change in a tubing run with a 5/16-inch outside diameter. Typical install scenarios include hydraulic control lines, instrumentation tubing, fuel systems, and other high-pressure fluid circuits where a compact elbow transition is needed. The flare end accepts 5/16-inch OD tubing flared to the SAE 37-degree standard, and the NPTF port threads directly into a standard pipe port or manifold. Sold in packages of five units per order.

Key Features

• 37-degree flare seat provides a metal-to-metal seal on the tube end
• 1/8-27 NPTF thread delivers a dryseal connection on the port end
• 6000 psi maximum working pressure rating for high-pressure service
• 500 degrees F maximum working temperature for elevated-temperature applications
• Steel construction for durability in demanding fluid system environments
• Meets ISO 8434-2, SAE 070202, and SAE J514 standards

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic, pneumatic, fuel, and instrumentation systems using 5/16-inch OD tubing with a 37-degree SAE flare and 1/8-27 NPTF ported connections.

Installation Notes

This fitting is typically installed by licensed pipefitters, hydraulic technicians, or fluid power mechanics. Depressurize and isolate the system completely before removing or installing any line fittings. Inspect the tube flare for cracks, ovality, or surface defects before assembly, as flare quality directly affects seal integrity. Torque the flare nut to the fitting body using proper flare-nut wrenches to avoid distorting the seat; refer to the system manufacturer or SAE J514 guidelines for assembly procedures.
