The PARKER 14-3/4 F5OG-S is a straight hydraulic pipe adapter designed to connect a 1-3/16-12 male straight thread O-ring port to a 3/4-inch female NPTF port. Built from zinc-plated steel, this adapter handles working pressures up to 4,000 psi, making it suitable for high-pressure hydraulic and industrial fluid power systems. The male end uses a straight thread with an O-ring face seal to prevent leakage at the port connection, while the female NPTF end creates a pressure-tight mechanical seal with the mating pipe thread. Licensed plumbers, hydraulic system technicians, and industrial maintenance professionals typically install this fitting during system assembly or repair.
This adapter is used in industrial and mobile hydraulic systems where a transition between straight thread O-ring boss ports and NPTF pipe thread connections is required. Typical install scenarios include hydraulic power units, manifolds, cylinders, and related fluid power assemblies operating at pressures up to 4,000 psi. It conforms to SAE 090156 standards, confirming dimensional and performance compliance for use in demanding hydraulic circuits.
Designed as an OEM-style replacement or new-installation fitting for hydraulic and industrial fluid power systems requiring a 1-3/16-12 male straight thread O-ring boss to 3/4-inch female NPTF adapter conforming to SAE 090156.
Installation should be performed by a qualified hydraulic technician or pipefitter. Depressurize and de-energize the hydraulic system fully before removing or installing any fittings. Inspect the O-ring for damage before assembly and replace if necessary; do not reuse a deformed or cut O-ring. Torque the fitting to the port manufacturer specification and verify system pressure integrity before returning the system to service.
