【Small Size and Large Flow】: The booster pump is only palm-sized but has a large flow, which is easy to carry and does not take up too much space. The maximum flow is 25L/min and the peak head is 21 meters, which can help you increase the water pressure and improve the comfort when using water..
【Automatic Flow Switch】: Automatic control can be realized by the water flow sensor switch: when the faucet is opened, the water pump is automatically turned on, and when the faucet is closed, the water pump is automatically turned off. Before turning on the pump, please turn on the faucet to make sure that there is water flowing through the pump..
【Safe and Silent】: 24V DC safety voltage, within the safe voltage range that the human body can withstand, the current is DC2.8A, super pressure and power saving. And adopts a variety of noise reduction technologies, no extra noise will be generated during pressurized work, providing a quiet and comfortable environment for the family..
【Easy Installation】: Provide necessary accessories, including bellows, sturdy stickers and some screws, base, power adapter. Easy to install, only a wrench can be connected to the pump, saving your installation cost..
【Widely Used】: Water pressure pump can be widely u....

Measures air pressure of the single pipe or differential pressure of 2 pipes. Has 11 selectable units of measurement kPa, psi, kgfcm2, ozin2, bar, mbar, inHg, mmHg, inH2O, ftH2O, cmH2O..
Best for measuring the ventilation and air condition systems. Widely used for gas measurement, calibration, and any troubleshooting of any gas pressure systems..
Max / minimum / Average reading record function.

Differential pressure measurement,Large LCD backlit dual display.

Works for all R-134A cans. Doesn't matter if it is the new EPA-required self-sealing freon can or the old-style single puncture bottle we got you covered..
Both our refrigerant can tap valves are made from brass, yes even the silver-colored self-sealing. The output is 1/4" flare, with a NEW 1/2" ACME adapter. We listen to what you the customer wants and have fixed the hose size issue with a free adapter..
Our valve core removal tool works on all Schrader valves.
from a compact car to a full-size Truck..
When selecting tools we look at quality, and function only. That is why we supply brass valves instead of aluminum. If you're not 100% satisfied please return it to Amazon. We buy tools we use on our vehicle, if it isn't to your standard let us know..
Only add R-134a to the low side (blue). "R134A flow" depends on the pressure differential between the can and the system. The can "cools" and the can pressure drops as you add it to the system slowing the flow of gas. Some people flip the can over and add liquid to speed things up, but if the liquid doesn't disperse before the compressor it can destroy the compressor. The slowing is not due to the valve or any other tool, it is just how it works..

845 Gallon Per Hour rating tackles any draining job at a fraction of the time. 66 PSI water pressure makes this pump perfect for irrigation, water transport or pump water. Ideal for sprinkling systems, flow irrigation systems, gardening, rain barrels, large aquariums and ground water..
