QWORK Fuel Hose Breakaway Coupling 3/4" Female Thread — Single-Use 2-Pack, 350 lb Auto-Seal for Tanker Hoses

QWORK Fuel Hose Breakaway is a single-use safety coupling with 3/4" female threads that automatically seals both ends if separated, sold as a 2-pack for tanker fuel hoses.

Designed for tank truck fuel hoses, this QWORK breakaway coupling helps reduce spill risk by mechanically shutting off fuel flow when excessive force disconnects the hose. Built for use with gasoline, diesel and biodiesel blends, the device installs directly onto the hose and is intended for one-time activation to preserve downstream fittings and limit environmental exposure.

How does the QWORK breakaway stop fuel leakage during a separation?

When the breakaway experiences a pull-off force beyond its design limit, internal valves automatically engage and close on both sides. This mechanical action isolates the hose and the vehicle, minimizing the volume of fuel released.

• Automatic dual-valve closure on separation
• Max pull-off force rated at 350 lbs to trigger sealing
• Single-use design prevents reactivation after a full separation
• Compatible with common petroleum fuels and biodiesel

What are the installation requirements for using this coupling on tankers?

The QWORK breakaway is intended to be fitted onto the end of the tanker’s fuel hose using its 3/4" female threaded connection. Installers should follow vehicle and hose manufacturer guidelines and ensure thread compatibility and proper torque during assembly.

• 3/4" female thread for direct hose attachment
• Fit to tanker hose end according to OEM recommendations
• Verify sealing surfaces and thread engagement before service
• Replace after activation; not designed for reuse

Which fuels and operating environments is this breakaway suitable for?

The coupling is engineered for use with gasoline, diesel and biodiesel fuels; the materials and valve design are selected to withstand common hydrocarbon fuels. It is meant for typical tanker and fuel delivery environments rather than specialty chemicals.

• Compatible: gasoline, diesel, biodiesel
• Not intended for aggressive solvents or non-petroleum chemicals
• Durable for outdoor fueling operations and road transport
• Designed to function reliably under standard temperature ranges

What performance limits and safety practices should users observe?

The breakaway activates at a maximum pull-off force of 350 lbs; operators should design hose routing and vehicle procedures to avoid unintended activation while still protecting equipment. Because the unit is single-use, keep replacements available and inspect regularly for wear or damage.

• Activation threshold: 350 lbs maximum pull-off force
• Single-use — replace after any full separation event
• Periodic inspection recommended for abrasion or thread damage
• Keep spare units on hand for prompt replacement

Who is this for: QWORK’s 3/4" female-thread breakaway is aimed at fleet operators, fuel delivery contractors, and service technicians who manage tanker fueling operations and need a reliable, single-use mechanical device to limit fuel escape during accidental hose separations. It suits businesses that handle gasoline, diesel or biodiesel and require a straightforward, replaceable safety coupling to protect equipment, personnel and the environment.
