Hydraulic Fittings for 70MPa Systems: Choose Reliability Over Risk

Let me be honest with you—if your hydraulic lines are pushing 10,000 PSI, the last thing you want to worry about is whether your fittings will hold up. That's why I'm genuinely excited about our TQ series that just came out of our workshop.

What's the Big Deal About 70MPa?

Most high pressure couplingson the market top out around 3,000–6,000 PSI. Our TQ series? It's rated at 70MPa (10,152 psi) compression resistance. That's not "high pressure"—that's Ultra High Pressure Couplers territory.

We're talking about systems where a weak connection means downtime, safety hazards, or worse. For applications like hydraulic rescue tools, heavy construction machinery, and mining equipment, every joint has to be bulletproof.

Here's what makes our High Pressure Quick Connect actually work:

Material: Nickel-plated steel construction—corrosion-resistant and tough enough to handle rough environments

Sealing: Axial sealing design that actually holds when pressure spikes

Temp Range: NBR seals good from -20°C up to +80°C

Standards: Meets GB/T 40565 series, compatible with similar models

Whether you need male Hydraulic Coupler fittings or the female side, we've got you covered. The quick coupler high pressure connection is secure and reliable—no leaks, no surprises.

A Quick Story

At Hejian Honglun Hydraulic Parts Co., Ltd. , we don't just manufacture quick couplings—we craft the connections that power industries worldwide. Founded in 2010, we've spent over 15 years designing, developing, and producing high-performance couplings. Today, we're a global leader trusted by clients in construction, energy, transportation, and beyond.

Every High Pressure Quick Release Fitting that leaves our factory gets tested. Not by a machine—by our team. The same people who designed it.

Where You'll Use These

If you're running:

Hydraulic power units that need frequent connect/disconnect

Mobile construction equipment operating in extreme conditions

Rescue tools where failure isn't an option

Industrial machinery requiring 70MPa capability

You need High Pressure Quick Release Couplings that don't compromise. The TQ series gives you a quick coupler that connects fast, seals tight, and stays that way.

The Bottom Line 

Other companies sell High Pressure Couplers that look good on paper but fail in the field. We don't play that game. Our TQ High Pressure Quick Connect Fittings are built by people who understand hydraulics—because that's all we've done for 15 years.
