20HB-24MORB STRAIGHT

Description & Features

Designed for straight-configuration hose-to-port connections, the 20HB-24MORB Straight adapter from Brennan Industries connects a 1-1/4 inch OD hose barb end to a 1-7/8-12 Male SAE O-Ring Boss port conforming to SAE J514. Constructed from straight steel, the fitting uses an NBR O-ring seal at the ORB end, providing reliable fluid containment in hydraulic systems handling petroleum-based and water-based fluids.

With an overall length of 1.500 inches and a secondary overall length of 1.270 inches, this fitting is suited for compact installation environments where space constraints are a consideration. The hose barb end accepts a 1.094 inch drill diameter, while the ORB end accommodates a 1.312 inch drill diameter. It is a practical choice for hydraulic circuits requiring a direct, non-adjustable barb-to-ORB transition without additional fittings or adapters in the line.
