#10 MJ X #20 MP ST.

Description & Features

Manufactured from straight steel, this male JIC to male NPTF adapter provides a reliable transition between two common hydraulic thread standards. The #10 MJ X #20 MP ST. connects a 7/8-14 Male JIC SAE 37-degree flare end (per SAE J514) to a 1-1/4-11-1/2 Male NPTF end (per SAE J476), with an overall length of 2.250 mm. Rated for dynamic pressures up to 3,000 PSI, it suits demanding hydraulic line connections where JIC and NPTF interfaces meet.

Part of Brennan Industries' Series 2404, this straight adapter is a practical solution for hydraulic systems requiring a direct, non-angled port-to-port connection. California residents should note that this product is subject to a Proposition 65 warning.
