1/8MNPTx1/4FNPT 90 SS

Description & Features

Machined from straight stainless steel stock, this 90-degree street elbow transitions a 1/8 in. Male NPTF inlet to a 1/4 in. Female NPTF outlet, making it well suited for connecting components where thread sizes differ and a direction change is required. Both thread connections conform to SAE J476, with the male end sized at 1/8-27 and the female end at 1/4-18.

The 1/8MNPTx1/4FNPT 90 SS is rated for dynamic pressures up to 6,000 PSI, suitable for demanding hydraulic and fluid power circuits. Stainless steel construction provides reliable resistance to corrosion and oxidation in harsh service environments. The compact form factor, with a centerline length of 0.900 in. and overall length of 0.880 in., supports tight-clearance installations without sacrificing flow path integrity.

This fitting is part of Brennan Industries' 5502-FG series. California residents: this product is subject to Proposition 65 warnings.
