A trusted global brand since 1917 

Yokohama isn’t just a hose manufacturer. It’s a global brand built on more than a century of innovation and quality. Since opening its doors in 1917, Yokohama has earned a worldwide reputation for producing high-performance rubber products trusted across industries - from automotive to mining and heavy machinery. 

Why Yokohama hoses matter 

Yokohama’s hydraulic hoses are engineered for mobile machinery working under extreme pressure and conditions. Every hose is built with top-grade rubber and high-tensile steel, and they’re tested well beyond industry minimums. 

Here’s what makes the difference: 

• Precision manufacturing for consistent quality 
• Impulse testing of over 1.2 million cycles, more than double the industry standard 
• Certified constant-pressure performance (ISO 18752) 
• Tighter bend radius and smaller outer diameter for easier routing 
• Highly abrasion-resistant cover that handles tough environments 
• Roughly 25% lighter than conventional spiral hose, making it easier to handle and improving fuel efficiency 

It’s a hydraulic hose system built for hard work and long service life.  

Why BOA Hydraulics chose Yokohama 

At BOA, we don’t just sell parts. We deliver integrated hydraulic systems designed to put you in control. Our team visited Yokohama’s factory in Japan to see their process firsthand. We saw the same diligence in their testing and manufacturing that we bring to every customer relationship. 

We now offer matched hose and fitting systems engineered to OEM standards. That includes crimp specifications, assembly support and full traceability. It’s everything you need to install with confidence and keep machines moving.  

Tested to outperform: Why Yokohama’s testing method matters. 

When it comes to hose testing, not all methods are equal. Yokohama goes further, pushing its hoses beyond standard industry protocols to make sure they’re ready for real-world punishment. 

While typical SAE and EN standard tests use a square pressure wave and max out at around 400,000 to 500,000 impulse cycles, Yokohama hoses are tested using a much tougher peak pressure method. This is known as the Komatsu and Hitachi spike testing standard – simulating the hammering conditions of heavy machinery under load. 

Here’s how Yokohama’s hoses are tested: 

• Impulse tested to 1.2 million cycles – more than double SAE/EN standards 
• Pressure testing at 150% of Max Operating Pressure (MOP) – most SAE hoses are tested at only 120% to 133% MOP 
• Test oil temperatures of up to 120°C – ensuring performance in extreme heat 
• Peak wave pressure cycles – replicating the real surges and stress that equipment generates in tough jobs 

This rigorous testing is why BOA trusts Yokohama to stand up in the harshest environments. It’s more than numbers on a spec sheet – it’s performance you can rely on when it counts.

Field-proven: over 7,000 hours and counting 

In the field, Yokohama hoses don’t just perform. They outperform. 

We installed a full set of 2-inch Yokohama Boom Arch hoses on two Hitachi EX1900 excavators — one at Rocklands Mine in Cloncurry, the other at Osborne Mine, 200km south. 

Both machines had previously run other brands of hose. These showed vertical cracks near the crimp within 1,000 hours and had already started to rust internally. 

The Yokohama hose at Rocklands ran for 4,200 hours before the mine ceased operations. The hoses were still in great condition. The other machine at Osborne is still running with the same Yokohama hose after 7,455 hours. There’s no visible damage or wear. Even under clamp contact, the hose holds up better than anything else on the market. 

That’s why we recommend running Yokohama hoses throughout the system. It prevents uneven wear, keeps clamps tight, and extends the life of your setup. 

We even use Yokohama on our flow meters when tuning hydraulic pumps. We have complete confidence in the product.
