This compact brass air shutoff valve is a heavy-duty emergency repair accessory designed for air brake trucks, semi-trailers and commercial vehicles. It serves two core critical functions: emergency air leak isolation for damaged brake diaphragms and manual front wheel brake release for maintenance work. Built with a solid one-piece brass valve body and precision copper core, this small-size cut-off switch features standard 18\*1.5 internal & external threads for universal compatibility with most heavy-duty truck front air brake lines. Its mini lightweight structure takes minimal storage space, making it an essential backup spare part for every truck driver to avoid costly roadside breakdowns and towing fees.
- Durable All-Brass Valve Construction The entire valve body is forged from thick solid brass with an internal copper core for outstanding pressure resistance, anti-rust and anti-leak performance under long-term high-pressure air brake operation. Matched with sturdy iron threaded nuts and external male threads, the valve withstands harsh vibration, temperature changes and road grime common in commercial trucking environments for long service life.
- Precision Smooth Thread Interface Standard 18*1.5 internal female thread + external male thread design with finely machined smooth threads for fast, tight leak-free installation onto front wheel air brake pipelines. Threads seal perfectly without stripping during frequent assembly and disassembly for routine maintenance or emergency repairs.
- Compact Mini One-Piece Body Design Overall length only 72mm, ultra-small streamlined one-piece structure that fits confined undercarriage mounting spaces on all standard heavy-duty trucks. Equipped with easy-grip plastic on/off handle (red/black options available) for quick single-hand operation to open or block air flow in seconds.
- Dual Multi-Purpose Functionality
- Emergency Air Leak Isolation: When brake chamber diaphragms crack and cause critical air leaks, install this valve to seal off the faulty line, allowing you to fully recharge air tanks and drive the rig off remote highways without waiting for expensive roadside tow service.
- Brake Release for Servicing: Mount on front steering wheel brake lines to manually cut air supply and disengage brakes, enabling easy tire changes, suspension inspection and axle maintenance without draining the full vehicle air system.
- Zero Air Leak Sealing Performance Integrated high-quality internal packing leather gaskets deliver complete airtight sealing when the valve is fully closed. No slow pressure loss during highway travel, eliminating partial brake failure risks caused by minor valve seepage.

- Emergency breakdown rescue for air brake commercial trucks, semi-trucks, trailers and delivery rigs
