Midland Industries 29SB-106 Brass Single Barb Connector

Product Description

The MIDLAND INDUSTRIES 29SB-106 is a single barb connector machined from brass, designed to transition a 5/8-inch single barb hose end to a 3/8-inch male NPTF threaded port. The barb end grips the interior of a compatible fuel hose to form a secure, leak-resistant connection, while the NPTF thread provides a dry-seal mechanical fit at the mating port. Rated to 150 psi maximum operating pressure and rated for service from -40 to 160 degrees F, this fitting handles the thermal and pressure cycles typical in fuel line applications. Plumbers, HVAC techs, and fuel system technicians install this type of fitting in both stationary and mobile equipment fuel circuits.

This connector is specified for use with SAE 30R7 and SAE 30R9 fuel hose, making it appropriate for gasoline and diesel fuel line assemblies in small engines, generators, and related equipment. The 3/8-18 NPTF thread size is a common port dimension found on carburetors, fuel pumps, fuel filters, and valve bodies. The single-barb design is well suited for low-to-medium pressure fuel circuits where a hose clamp is used to secure the hose over the barb.

Key Features

• 5/8-inch single barb end for secure hose grip on SAE 30R7 and SAE 30R9 fuel hose
• 3/8-18 male NPTF thread provides a dry-seal mechanical fit without sealant tape on a properly gauged port
• 150 psi maximum operating pressure rating
• Operating temperature range of -40 to 160 degrees F
• Brass construction resists corrosion in fuel service environments

Compatibility

Designed for use with SAE 30R7 and SAE 30R9 fuel hose with a 5/8-inch inside diameter, connecting to equipment ports with a 3/8-18 NPTF male thread.

Installation Notes

Installation should be performed by a qualified technician following applicable fuel system service codes and equipment manufacturer guidelines. Shut off all fuel supply and relieve line pressure before disassembling any fuel circuit component. NPTF fittings rely on thread interference for sealing; inspect threads on the mating port before assembly and do not overtighten. Secure the hose over the barb with an appropriately rated hose clamp after seating the hose fully onto the barb.
