Parker BD-16257 Hydraulic Hose Swivel Adapter 4000 Psi

Product Description

The PARKER BD-16257 is a straight swivel adapter designed for hydraulic hose assemblies operating at up to 4,000 psi. Manufactured from steel with SAE ORB (O-Ring Boss) porting, it accepts a 3/4-inch hose diameter and threads to a 1-1/16-12 port. The swivel design allows the hose to rotate freely after connection, reducing torsional stress on the line and simplifying routing in tight installations. This fitting is part of Parker's 0507 series and conforms to SAE 140157 standards. It is installed by hydraulic technicians and fluid power specialists in mobile, industrial, and heavy-equipment applications.

This adapter suits systems where a fixed-end fitting would place unwanted twist or tension on the hose assembly. The SAE ORB interface provides a positive face-seal connection that resists leakage under sustained pressure cycling. Typical applications include mobile equipment hydraulics, construction machinery, agricultural equipment, and industrial power units where a swivel connection is required between a 3/4-inch hose and a 1-1/16-12 ORB port. The straight configuration keeps the routing in-line without angular offset.

Key Features

• 4,000 psi maximum working pressure rating
• Swivel design reduces hose torsion and simplifies routing
• SAE ORB (O-Ring Boss) thread interface for leak-resistant sealing
• Steel construction for durability under pressure cycling
• Straight configuration for in-line hose-to-port connections
• Conforms to SAE 140157 standard, Parker 0507 series

Compatibility

Designed for use with 3/4-inch hydraulic hose assemblies terminating at a 1-1/16-12 SAE ORB port. Suitable for hydraulic systems requiring a swivel adapter that meets SAE 140157 specifications.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and bleed down the hydraulic system completely before removing or installing any fittings. Inspect the O-ring seat on the receiving port for nicks or contamination before assembly, and verify the O-ring is properly seated before torquing. Do not use thread sealant tape on SAE ORB connections, as the seal relies on the O-ring face, not the threads.
