Parker BD-1J7771212-1 Hydraulic Hose Fitting 45 Elbow

Product Description

The PARKER BD-1J7771212-1 is a 45-degree elbow hydraulic hose fitting designed for use in high-pressure hydraulic plumbing assemblies. Manufactured from steel, this fitting features a Seal-Lok face seal connection and threaded interface with a 1-3/16-12 thread size. It is sized for 0.75 inch (12 mm) inside diameter hose, corresponding to a hose size 12 designation. Licensed hydraulic technicians and fluid power specialists install this fitting in mobile equipment, industrial machinery, and other hydraulic circuit applications where a reliable, leak-resistant 45-degree directional change is required at a hose-to-port junction.

This fitting is intended for hydraulic plumbing installations where a 45-degree angled hose termination is needed to route hose runs within tight or angled geometries. The Seal-Lok face seal design provides a positive metal-to-metal seating surface that minimizes leakage risk under dynamic pressure conditions. It is compatible with Parker 787TC and 797TC hose series and conforms to ISO 12151-1-SWE45, making it suitable for assemblies that must meet international hydraulic fitting standards. Typical applications include construction equipment, agricultural machinery, and industrial hydraulic systems.
