Parker BST-N2M-787 Hydraulic Hose Coupler Brass Nptf

Product Description

The PARKER BST-N2M-787 is a brass hydraulic hose coupler designed for threaded NPTF connections in hydraulic fluid systems. It accepts a 0.25 inch inside diameter hose and connects via a 1/4-18 NPTF thread, providing a pressure-rated, leak-resistant seal without a secondary sealant when properly installed. The all-brass construction resists corrosion and handles the demands of hydraulic lines in industrial and mobile equipment applications. This coupler is typically installed by hydraulic system technicians and maintenance mechanics during hose assembly or replacement service.

This coupler suits residential and light commercial hydraulic applications where a 1/4 inch hose termination is required at an NPTF-threaded port. Common install scenarios include hydraulic tool lines, fluid transfer assemblies, and equipment service manifolds. Sold in individual units with a minimum order quantity of 5, this part is stocked as a standard replacement coupler for ongoing maintenance programs.

Key Features

• Brass construction for corrosion resistance in hydraulic fluid environments
• NPTF threaded connection provides a dry-seal fit at the port interface
• 0.25 inch inside diameter hose acceptance matches standard 1/4 inch hydraulic hose
• 1/4-18 thread size for direct engagement with matching NPTF ports
• Compact, lightweight form factor at 0.01 pounds for space-constrained assemblies

Compatibility

Designed as an OEM-style replacement coupler for hydraulic hose assemblies requiring a 1/4 inch ID, 1/4-18 NPTF threaded brass coupler connection.

Installation Notes

Installation should be performed by a qualified hydraulic system technician. Depressurize and isolate the hydraulic circuit fully before removing or installing any coupler. NPTF threads are designed to seal on the thread form itself; verify thread condition and cleanliness before assembly. Torque to the fitting manufacturer specifications for the port material and do not overtighten brass fittings into cast or aluminum ports.
