1. Professional Pipe Stopper Set: This pipe stopper kit includes three differently sized PPR pipe stopper needles (1.27 cm, 1.9 cm, and 1 inch), a release pin, a doublerod Thandle wrench, and extra rubber sleeves, making it suitable for both household repairs and professional plumbing work. Stop leaks instantly without shutting off your main water supply! 2. Effective Under Pressure: Our innovative pipe stoppers can seal under 27 kg of water pressure without needing to drain the system. This means you can perform repairs even if a broken water pipe or faulty main valve cannot be closed, saving you time and frustration in emergency plumbing situations. 3. Ergonomic THandle Wrench Design: The included Thandle wrench tool features an additional protective rod that reduces torque and energy consumption during operation. This thoughtful design sets our product apart, making it easier to use and more comfortable for your hands during pipe repairs. 4. Versatile Application: With heat resistance, these plumbing tools work excellently for indoor and outdoor repairs on various surfaces, including walls, corners, and tunnels. Simply place the pipe stopper on the tube and use the pin to slide the rubber sleeve, stopping the water flow immediately.
