how to make a fire hose washer

Image
Fire hoses are made in a variety of sizes for specific user requirements. Portable home fire pump equipment hoses typically use small diameter connection fittings and washers similar to garden hoses. The washers compress as the connections tighten to prevent water leakage at the joints when the hose is pressurized. While the sealing washers are usually available from fire equipment suppliers, you can make your own washers using gasket material and a few tools. Measure the inside diameter of the female fire hose fitting using a vernier caliper. Lock the caliper jaws by tightening the knurled set screw at the top of the caliper clockwise by hand. Lay out a sheet of 1/8-inch thick red rubber gasket material on a hard flat surface. Open the points of a math compass to one-half the distance of the caliper jaws. Rotate the compass in either direction to mark a full circle on the gasket material. Loosen the caliper set screw and close the jaws of the caliper. Insert the caliper jaws into ...

What are the different types of refrigerants gas?

Refrigerants gas play a very important part in air conditioning. Usually, they're found in gaseous or liquid form. The refrigerant can be used to cool a particular space. There are several types of refrigerants that can be used to absorb heat from a particular area and disperse it to other areas where heat is needed. These refrigerants gas are used in a variety of devices, such as air conditioners and coolers. They generally use the thermodynamic occurrence of stage transition to convert gasoline to liquid and vice versa. Refrigerant is an element in liquid or gas form. Specific areas in the refrigeration series use refrigerants for cooling. This process takes heat from the space and then releases it into some other area. This is the use of the refrigerant. The refrigerant process begins with the evaporator of this system. The refrigerant liquid will absorb warmth and eventually become vapor at low pressure. The vapor propagates to the compressor component of the system. Compresso...
