Midland Industries SS2707-06-06 Bulkhead Union 3/8 in Fnpt

Product Description

The MIDLAND INDUSTRIES SS2707-06-06 is a bulkhead union fitting designed to create a secure, leak-free pass-through connection in a panel, tank wall, or bulkhead. Both ends accept 3/8-inch Female NPT connections with a 3/8-18 thread form, making this a straight-through union for installations where the fitting must be mounted through a structure. Constructed from 316 stainless steel, this fitting handles a maximum operating pressure of 5300 psi and is rated to 1000 degrees F, making it suitable for high-pressure and high-temperature fluid or gas systems. Plumbers, pipefitters, and industrial service technicians are the typical installers.

This fitting is used in industrial piping, hydraulic, pneumatic, and process fluid systems where a 3/8-inch NPT line must pass through a bulkhead, panel, or vessel wall. The SS2707 Series FNPT bulkhead union is common in stainless steel pipe adapter applications across oil and gas, chemical processing, marine, and heavy mechanical service environments. Its 316 stainless steel construction provides corrosion resistance in aggressive media and outdoor or wet environments where carbon steel fittings are not appropriate.

Key Features

• 316 stainless steel construction for corrosion resistance in harsh and wet environments
• Maximum operating pressure of 5300 psi for high-pressure system use
• Temperature rating up to 1000 degrees F for high-heat process applications
• 3/8-18 Female NPT threads on both ends for standard pipe compatibility
• Bulkhead union design allows mounting through panels, tanks, or vessel walls

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 316 stainless steel pipe adapter systems using 3/8-inch Female NPT connections, consistent with the SS2707 Series FNPT Bulkhead Union product family.

Installation Notes

Installation should be performed by a qualified pipefitter or plumber following applicable codes such as the IPC or ASME B31.3 for process piping. Depressurize and isolate the system completely before removing any existing fitting or mounting this union through a bulkhead. Use an appropriate thread sealant rated for the operating temperature and media; do not overtighten NPT threads, as this can crack stainless fittings. Verify panel or wall thickness is compatible with the fitting body length before installation.
