Midland Industries SS306-24 Bulkhead Locknut 1-1/2 in Female Jic

Product Description

The MIDLAND INDUSTRIES SS306-24 is a bulkhead locknut designed to secure hydraulic and fluid system fittings through panel walls or bulkheads. Machined from 316 stainless steel, it provides strong resistance to corrosion in demanding environments including marine, chemical processing, and high-temperature industrial applications. The 1-1/2 inch Female JIC connection with a 1-7/8-12 thread accommodates high-pressure lines rated up to 2000 psi and operating temperatures up to 1000 degrees F. Licensed plumbers, pipefitters, and hydraulic system technicians typically handle installation of this fitting type.

This bulkhead locknut is suited for use in both commercial and industrial fluid systems where stainless steel fittings are required to maintain integrity under elevated pressure and temperature conditions. It is commonly installed in hydraulic lines, fuel systems, and process piping where a secure, leak-resistant panel mount connection is essential. The Female JIC configuration makes it compatible with standard JIC flare-end tube fittings used across a wide range of fluid handling systems.

Key Features

• 316 stainless steel construction for superior corrosion resistance
• 1-1/2 inch Female JIC connection for secure flare-end tube coupling
• 1-7/8-12 thread specification for precise panel-mount fitment
• 2000 psi maximum operating pressure for high-pressure fluid lines
• 1000 degrees F maximum operating temperature for extreme heat environments
• Bulkhead locknut design for through-panel installation

Compatibility

Designed as an OEM-style replacement or direct-install bulkhead locknut for systems requiring 316 stainless steel SS0306 Series Female JIC adapters in panel-mount hydraulic and fluid piping applications.

Installation Notes

Installation is typically performed by licensed pipefitters, hydraulic technicians, or plumbers working with industrial fluid systems. Depressurize and drain the system fully before removing or installing any fittings. Use appropriate wrenches sized to the fitting hex; avoid pipe wrenches that can deform the fitting body. Follow applicable industry standards such as the IPC or system-specific hydraulic codes when torquing fittings and verifying joint integrity after installation.
