Parker 11343-8-8 Male Nptf Swivel Fitting 0.5 in Hydraulic

Product Description

The PARKER 11343-8-8 is a male NPTF pipe swivel fitting designed for hydraulic hose assemblies in industrial and mobile equipment applications. Manufactured from steel with a threaded connection type, this straight fitting accepts hoses with a 0.5-inch inside diameter (hose size 8) and features a 1/2-inch NPTF thread. At 3.52 inches overall length, it is built for reliable, leak-resistant connections in high-pressure hydraulic systems. Licensed HVAC, plumbing, and industrial fluid-power technicians rely on NPTF thread forms for their dry-seal performance without the need for additional thread sealant under most conditions.

This fitting is intended for use in hydraulic hose assemblies where a swivel connection at the male NPTF pipe end is required. The swivel design allows the hose to be positioned without twisting the hose body during installation or operation, reducing stress on the assembly. It is suited for both stationary industrial hydraulic systems and mobile equipment hydraulic circuits. According to the manufacturer, this fitting is compatible with Parker hose series 187 TC, 187 ST, 302, 304, 387 TC, 387 ST, 422, 424, 426, 436, 471TC, 471ST, 472TC, 482TC, 482ST, 487 TC, 487 ST, 722 TC, 722 ST, 787 TC, 787 ST, 797 TC, 797 ST, and 881 hoses.

Installation Notes

Installation should be performed by a qualified fluid-power technician or pipefitter familiar with hydraulic system assembly. Depressurize and lock out the hydraulic system completely before removing or installing any fittings. NPTF fittings are designed for dry-seal engagement; inspect threads for damage before assembly and follow applicable industry torque guidelines for steel hydraulic fittings. Do not over-torque, as this can crack the port or distort the fitting body.
