Midland Industries 28301SS Bulkhead Adapter 1/4 in Nptf Ss

Product Description

The MIDLAND INDUSTRIES 28301SS is a 316L stainless steel bulkhead adapter designed to pass a fluid line through a panel, tank wall, or enclosure while maintaining a secure, leak-resistant seal on both sides. The fitting features 1/4-in Female NPTF connections on both ends with a 1/4-18 thread form, a 1.063-in hex for wrench engagement, and a compact 0.748-in body length. Rated to 1450 psi maximum operating pressure and a temperature range of -20 to 360 degrees F, this adapter suits demanding hydraulic, pneumatic, and process-fluid installations. Plumbers, pipefitters, and industrial maintenance technicians install this type of fitting when routing lines through bulkheads or vessel walls.

The 28301SS is suited for residential and commercial plumbing panels, hydraulic reservoirs, pneumatic enclosures, and process equipment where a through-wall connection must hold rated pressure. The 316L stainless steel construction resists corrosion in wet, chemical, and marine environments. Its compact hex and body length make it practical in tight panel layouts where clearance is limited. No specific model or system compatibility data was provided in the product input beyond these general application characteristics.

Key Features

• 316L stainless steel construction for corrosion resistance in harsh and wet environments
• 1450 psi maximum operating pressure rating for hydraulic and high-pressure pneumatic service
• Operating temperature range of -20 to 360 degrees F
• 1/4-18 Female NPTF thread on both ends for leak-free tapered thread engagement
• 1.063-in hex allows standard wrench installation and removal
• Compact 0.748-in body length fits tight panel and enclosure clearances

Compatibility

Designed as a direct-fit bulkhead adapter for 1/4-in NPTF female thread applications in 316L stainless steel bulkhead fitting assemblies across hydraulic, pneumatic, and process-fluid systems.

Installation Notes

Installation should be performed by a qualified pipefitter or plumber following applicable IPC or facility-specific piping codes. Depressurize and isolate the system completely before removing or installing any bulkhead fitting. NPTF threads are designed for metal-to-metal sealing; inspect threads for damage before assembly and apply appropriate thread sealant per the system fluid compatibility requirements. Do not over-torque the fitting - use a calibrated wrench on the hex flats and follow standard NPTF assembly practice for the thread size.
