FS1703-16-16 ORFS to No-Braze Flange 45° Elbow Adapter | SAE Code 61 Steel Hydraulic Fitting

Product Description

The FS1703-16-16 ORFS to No-Braze Flange 45° Elbow Adapter Code 61 is a high-quality hydraulic fitting specifically designed to create a strong, leak-resistant transition between an O-Ring Face Seal connection and an SAE Code 61 hydraulic flange port. Built from durable forged steel, this adapter provides the angled configuration needed for efficient hose routing while maintaining exceptional structural integrity.

Connection configuration:

• Thread 1: Male ORFS – Nominal Size 16
• Thread 1 Size: 1 7/16-12
• Thread 2: SAE Code 61 Flange – Nominal Size 16
• Flange Size: 1 inch

Designed for hydraulic systems with operating pressures up to 3,000 PSI, this adapter is optimized for use in industrial machinery, mobile equipment, hydraulic manifolds, and heavy-duty fluid power circuits. Whether used in new OEM assemblies or replacement maintenance applications, the FS1703-16-16 delivers dependable performance you can trust.

This hydraulic elbow adapter incorporates Male ORFS flat face sealing technology, one of the most reliable thread sealing systems in the fluid power industry. ORFS fittings use a precision-machined flat seat combined with an elastomeric O-ring to form a tight metal-to-metal seal. This method ensures consistent performance in demanding environments where high vibration, temperature variation, and pressure surges are common.
