Midland Industries 46540 Marine Bulkhead Connector Brass

Product Description

The MIDLAND INDUSTRIES 46540 is a brass marine bulkhead connector designed to pass a fuel or fluid line through a panel, bulkhead, or deck wall with a secure, leak-resistant seal. Both ends accept 5/16-inch single-barb hose connections, making it a symmetrical, straight-through fitting. Rated to 1200 psi maximum operating pressure and capable of handling temperatures from -65 to 250 degrees F, this connector is built for demanding marine environments where corrosion resistance and pressure integrity are non-negotiable. Its all-brass construction resists the corrosion common in wet, saltwater-adjacent installations.

This fitting is suited for marine fuel systems, hydraulic lines, and fluid transfer applications where a hose must pass through a structural panel or bulkhead. It is commonly installed in boat fuel systems, bilge plumbing, and similar applications requiring a pressure-rated through-hull or through-panel connection. Marine technicians and experienced boat mechanics are the primary installers. The compact profile at 2.25 inches in length fits in tight panel spaces typical of marine cabinetry and engine compartments.

Key Features

• 1200 psi maximum operating pressure for high-demand fuel and fluid systems
• -65 to 250 degrees F operating temperature range suits fuel, hydraulic, and cooling line applications
• 5/16-inch single barb on both ends for straight-through hose-to-hose bulkhead routing
• All-brass construction provides corrosion resistance in marine and wet environments
• Compact 2.25-inch length fits tight panel and bulkhead installations

Compatibility

Designed as an OEM-style replacement or new-installation brass bulkhead fitting for marine fuel and fluid systems requiring a 5/16-inch single-barb connection on each side.

Installation Notes

Installation is typically performed by a marine technician or qualified mechanic. Shut off the fuel supply or depressurize the fluid system completely before removing or installing any bulkhead fitting. Ensure the panel or bulkhead hole is sized correctly for the fitting body and that the locknut is tightened sufficiently to compress the sealing surface without cracking the panel material. Follow applicable ABYC standards and engine manufacturer guidelines for marine fuel system work.
