Gates G25120-1210 MegaCrimp Male O-Ring Boss Hydraulic Hose Coupling

The Gates G25120-1210 MegaCrimp coupling is a straight male O-ring boss hydraulic hose fitting designed for use with 3/4" (12 dash size) hydraulic hose. This coupling features a 7/8-14 ORB thread connection and is engineered to deliver leak-proof performance in demanding hydraulic applications.

Patented C-Insert Technology:

The MegaCrimp coupling features Gates' innovative patented C-insert that attaches to the ferrule, accommodating hoses of different constructions and wall thicknesses. This design ensures crimping forces are evenly distributed to form a concentric seal, simplifying inventory requirements since one coupling size can accommodate various hose outside diameters on both one-wire and two-wire braid hydraulic hoses.

Key Features:

• Robust bite-the-wire crimp design for secure hose retention
• Tested to an industry-leading 1,000,000 impulse cycles for exceptional durability
• Environmentally-friendly TuffCoat plating provides 347% better corrosion resistance than SAE standards
• Fully qualified EN-performance coupling meeting SAE and ISO standards
• Hose inside diameter: 0.752 inches (3/4")
• Thread size: 7/8-14 ORB (O-Ring Boss)
• Material: Steel with zinc plating
• Straight configuration for direct connections

The G25120-1210 coupling is ideal for hydraulic systems in automotive, heavy-duty truck, construction equipment, and industrial machinery applications where reliable, leak-free connections are critical. The coupling's design helps prevent common hydraulic leak issues while providing world-class performance and simplified installation.
