Midland Industries HNV14MB Iso-b Quick Disconnect Plug Brass

Product Description

The MIDLAND INDUSTRIES HNV14MB is a brass ISO-B interchange quick disconnect pipe plug designed for hydraulic systems requiring fast, leak-free line disconnections. The plug features a 1/4-inch body with a 1/4-inch female NPT connection and a 1/4-18 thread specification. It is rated for a maximum operating pressure of 5000 psi and handles temperatures from -40 to 250 degrees F, making it suitable for demanding hydraulic service environments. Licensed hydraulic technicians and plumbing professionals install this fitting in mobile and industrial hydraulic circuits where tool-free line disconnection is required.

This plug is used in hydraulic quick disconnect applications across residential, commercial, and industrial settings. It is rated for use in high-pressure hydraulic lines where ISO-B interchange compatibility is required. The female NPT port allows direct connection to standard threaded hydraulic components. Typical installations include hydraulic power units, mobile equipment, and fluid transfer systems where secure, pressure-rated disconnects are necessary.

Key Features

• ISO-B interchange design for compatibility with standard quick disconnect couplers
• Maximum operating pressure of 5000 psi for high-pressure hydraulic service
• Wide temperature range of -40 to 250 degrees F for varied operating conditions

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed plumber. Depressurize and isolate the hydraulic circuit fully before removing or installing any quick disconnect fitting. Use appropriate thread sealant rated for hydraulic service and verify the female NPT connection is clean and free of debris before makeup. Follow applicable industry standards and equipment manufacturer guidelines for hydraulic fitting installation.
