Parker BD-101771212-1 Male Rigid Hose Fitting 3/4-14 Nptf

Product Description

The PARKER BD-101771212-1 is a male rigid straight fitting designed for hydraulic hose assemblies. It provides a secure, threaded NPTF connection between the hose end and a port or system component, sealing on the threads to prevent fluid leak paths under pressure. Constructed from steel, this fitting accepts hose with a 0.75 inch inside diameter and features a 3/4-14 NPTF thread size. Overall length is 3.43 inches. The straight configuration suits inline connections where hose routing does not require an angled transition. Licensed hydraulic technicians and fluid power mechanics are the typical installers for this component.

This fitting is intended for use in hydraulic systems where Parker Series 77 hose is employed. It is rated for use with Parker 711, 721, 721TC, 721ST, 722TC, 772TC, 772ST, and 774 hose series. Applications span industrial and mobile hydraulic equipment where a reliable, leak-free male rigid end connection is required. The NPTF thread form provides a mechanical seal without relying solely on a sealant, making it appropriate for higher-pressure hydraulic circuits in both stationary and mobile equipment.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and isolate the hydraulic circuit completely before removing or installing any hose fittings. Inspect threads and sealing surfaces for damage before assembly and apply thread sealant or tape only as recommended by the system designer for NPTF connections. Torque to system and hose manufacturer specifications and verify for leaks before returning the system to service.
