Parker BD-16N7720-20-1 Hydraulic Fitting 90 Elbow

Product Description

The PARKER BD-16N7720-20-1 is a 90-degree elbow hydraulic hose fitting designed for high-pressure fluid power systems. Manufactured from steel, this flanged fitting connects to 1.25-inch inside diameter hose and accepts a 1-1/4-inch thread. It conforms to ISO 12151-3-E90M-S and is built to SAE dimensional standards, making it a reliable choice for hydraulic plumbing where a right-angle transition is required. The flanged connection style provides a secure, leak-resistant joint under system pressure. Hydraulic technicians and fluid power specialists install this type of fitting during assembly or field repair of hydraulic lines.

This fitting is suited for industrial and mobile hydraulic applications where a 90-degree directional change in the hose routing is needed. It is part of the Parker Series 77 fitting family and is specified for use with 787TC and 797TC hose products. Typical installations include construction equipment, agricultural machinery, and industrial hydraulic circuits that require SAE-standard flanged connections at hose termination points.
