12MORB-20FORB STRAIGHT REDUCER

Description & Features

Designed for reducing connections between mismatched O-ring boss port sizes, the 12MORB-20FORB Straight Reducer transitions from a 1-5/8-12 female SAE O-ring boss port to a 1-1/16-12 male SAE O-ring boss end. Both threads conform to SAE J514, making this fitting suitable for hydraulic circuits where standardized ORB connections are required.

Machined from straight steel with an NBR O-ring seal, this fitting provides a leak-resistant metal-to-metal and elastomer-sealed connection in a compact straight body with an overall length of 2.000 inches. Manufactured by Brennan Industries as part of the 6410-O series, it is well suited for hydraulic lines requiring a size reduction without a change in orientation. California residents should refer to applicable Prop 65 warnings for this product.

Reckon this'll fit my setup? Got a 1-5/8-12 female port I need to bring down to a 1-1/16-12 male.

Designed to adapt between different sized SAE O-ring boss ports, this straight reducer should do the trick when you're connecting a 1-5/8-12 female to a 1-1/16-12 male.
