A large basin wrench Large basin wrench, with jaws oriented to apply torque in counter-clockwise direction. A basin wrench, sometimes called a sink wrench, is a plumbing tool which is used in confined spaces to turn fasteners and pipes that would be difficult or impossible to reach with a plumber wrench or other types of wrenches.

A plumber wrench A plumber wrench, with the key ring on the thread of the left handle Johan Petter Johansson with his wrench. A plumber wrench (or plumber's wrench, pipe wrench, Swedish wrench or Swedish pattern wrench [1]) is a form of plier described as a pipe wrench that uses compound leverage to grip and rotate plumbing pipes.
A pipe wrench is any of several types of wrench that are designed to turn threaded pipe and pipe fittings for assembly (tightening) or disassembly (loosening). The Stillson wrench, or Stillson-pattern wrench, is the usual form of pipe wrench, especially in the US. The Stillson name is that of the original patent holder, who licensed the design ...
Turning a valve knob or lever adjusts flow by varying the aperture of the control device in the valve assembly. The result when opened in any degree is a choked flow . Its rate is independent of the viscosity or temperature of the fluid or gas in the pipe, and depends only weakly on the supply pressure , so that flow rate is stable at a given ...
Replacing a valve stem. A valve stem is a self-contained valve that opens to admit gas to a chamber (such as air to inflate a tire), [1] and is then automatically closed and kept sealed by the pressure in the chamber, or a spring, [2] [3] or both, to prevent the gas from escaping.
The valve stem D moves up to open the valve discs C. James Watt was using poppet valves to control the flow of steam into the cylinders of his beam engines in the 1770s. A sectional illustration of Watt's beam engine of 1774 using the device is found in Thurston 1878:98, [ 13 ] and Lardner (1840) provides an illustrated description of Watt's ...
The term wrench is generally used for tools that turn non-fastening devices (e.g. tap wrench and pipe wrench), or may be used for a monkey wrench—an adjustable pipe wrench. [1] In North American English, wrench is the standard term. The most common shapes are called open-end wrench and box-end wrench.
A click torque wrench. A torque wrench is a tool used to apply a specific torque to a fastener such as a nut, bolt, or lag screw.It is usually in the form of a socket wrench with an indicating scale, or an internal mechanism which will indicate (as by 'clicking', a specific movement of the tool handle in relation to the tool head) when a specified (adjustable) torque value has been reached ...
