BRENNAN ADAPTER SS

Description & Features

Constructed from stainless steel, this straight adapter from Brennan Industries connects a 1-1/16-12 Male SAE O-Ring Boss port (SAE J514) to a 1/2-14 Male NPTF thread (SAE J476), making it well-suited for hydraulic systems where dissimilar thread types must be joined in a single inline fitting. The O-ring boss end uses an NBR O-ring seal, providing reliable leak resistance at the boss connection.

The Brennan Adapter SS belongs to the 6401-O series and has an overall length of 1.840 inches. Stainless steel construction makes it appropriate for applications where corrosion resistance is a priority. The Male NPTF thread on the secondary end provides a pressure-tight mechanical seal without the need for additional sealant when properly engaged.

Will this adapter hold up okay in a hydraulic system that sees pretty high pressure, or should I be looking at something else?

This Brennan adapter is constructed from stainless steel, making it suitable for hydraulic systems where corrosion resistance is a key concern. The male NPTF thread is designed to provide a pressure-tight mechanical seal without needing any extra sealant, provided it's properly engaged.
