Midland Industries 61153 Quick Disconnect Wingnut Coupler Brass

Product Description

The MIDLAND INDUSTRIES 61153 is a brass quick disconnect wingnut coupler designed for hydraulic line connections in demanding fluid-power applications. It features a 1-inch FNPT connection on both ends with a 1-11-1/2 thread standard, and is rated for a maximum operating pressure of 3000 psi. The coupler is built with a steel wing nut for hand-tightened, tool-free engagement and disconnection. Its brass body provides corrosion resistance across a wide operating temperature range of -40 to 250 degrees F. Hydraulic technicians and plumbers working on high-pressure fluid systems select this fitting for reliable, no-spill dry-break coupling performance.

This coupler is suited for industrial hydraulic systems, mobile equipment fluid lines, and high-pressure service applications where fast line disconnection is required. The 3000 psi dry-break no-spill design minimizes fluid loss during disconnect, making it appropriate for both stationary and mobile hydraulic circuits. The 1-inch body size accommodates standard 1-inch FNPT ported components, and the unit is commonly installed in agricultural, construction, and industrial equipment fluid systems requiring routine service disconnects.

Key Features

• 3000 psi maximum operating pressure rating for high-pressure hydraulic service
• Dual 1-inch FNPT connections with 1-11-1/2 thread for standard pipe compatibility
• Brass body construction for corrosion resistance in hydraulic fluid environments
• Steel wing nut enables hand-tightened connection without additional tools
• Dry-break no-spill design minimizes fluid loss during line disconnection
• Wide operating temperature range of -40 to 250 degrees F

Compatibility

Designed as an OEM-style replacement or direct-fit coupling for hydraulic systems using 1-inch FNPT ported components rated to 3000 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician or plumber familiar with high-pressure fluid systems. Always depressurize and isolate the hydraulic circuit completely before removing or installing any coupling. Apply appropriate thread sealant to FNPT connections per the system manufacturer's requirements and applicable industry standards. Inspect the coupling body and wing nut for damage or debris before use, and verify all connections are fully engaged before returning the system to service.
