Features
  • Feel Better in Summer - Cold and warm air conditioning air is controlled by the duct control motor, is not felt when in cold weather. But when the weather is hot, because his warm air is not closed tightly, some warm air will go to the cold air, which will affect the cooling effect, and the fuel consumption will increase obviously. After installing the warm water valve, the warm water inside and outside will not circulate, and the temperature of the warm water tank in the cab will naturally drop.
  • Application - The bypass valve can control 4 channels respectively to form 2 different flow directions. Widely used in pneumatic system, such as propane gas air hose, fuel line. It can also be used in the reconstruction of automobile heating valve. The purpose of this valve is that the warm water from the control valve is sent to the warm water tank in the cab.
  • Solid Connection - The 4-Way shaped hose barb ball valve can be solid connected to the hose (Fit hose which ID of 16mm). Keep the hose incision flat. It is better to use with clamps. Tighten clamps as tightly as possible to prevent leakage.

Features
  • This kit stops hot coolant from flowing to your heater core from the engine thus not allowing hot air to blend with the cold air behind the dash. This is often caused by a faulty blend door or simply a poor design from the vehicle manufacturer. This kit will NOT fix a non-functioning air conditioner. This kit simply blocks hot air from being introduced into a function air conditioning system. If you have a problem with hot air bleeding into your A/C system you can expect this kit to allow your A/C to blow 8-15 cooler at the vents!
  • This kit installs in minutes without making any permanent mods to your vehicle. NO HOSE CUTTING REQUIRED! With this kit you can control flow to your heater core with a turn of the handle!
  • Easy 5 Minute Install. Locate your heater core inlet hose. There will be two hoses coming from the firewall. One is the heater core "in" and the other is the "out". This kit MUST be installed on the "IN" hose. Follow the hoses from the firewall and install this kit on the other end. Remove the vehicle heater hose from the port on the engine and install the supplied hose, valve, and clamps. This kit can be installed on either end of the heater IN hose. SEE PHOTOS TO THE LEFT.
  • This kit is 100% safe for your vehicle and won't cause any damage or Check Engine Lights. This kit is comprised of PREMIUM components that WILL NOT fail.
  • This PREMIUM kit is MADE IN THE USA and includes - ONE Hi-Temp/Hi-Pressure Shut off Valve, ONE 4 inch Hi-Temp/Hi Pressure Heater Hose, THREE Stainless Steel Smooth Edge Band Clamps that WILL NOT cut into your hoses
  • This Kit includes a 4 inch section of high quality heater hose so you do not need to cut or modify your OEM heater hose to install this valve. Install the supplied valve at the END of your OEM hose and then attach the valve and supplied 4 inch hose to your engine outlet. On some vehicles it will not be easily accessible to install this kit on the engine side of the heater inlet hose. If this is your case you can also install the bypass kit on the fitting at the firewall where the inlet hose attaches.
  • This kit fits all 5/8 inch and 3/4 inch heater hose systems which covers about 99% of all cars and trucks out there.
  • This kit DOES fit 5/8 inch hoses. It does take a little M-A-N to get a 5/8 inch hose on the nipple, if you can't get it on you probabaly shouldn't be working on vehicles or perhaps you should get your wife to help you. A little soapy water might also help.
