A similar bonding jumper wire is used between the inlet and outlet of gas meters, but here the purpose is to avoid having a substantial voltage difference between the building’s grounding electrode(s) and buried natural gas lines appear across the gas meter during the brief interval when a line to ground fault is conducting before the ...
For example, a control panel door may have a bonding jumper across the hinges so that the metal door is effectively connected to ground, since the hinges may not provide a reliable contact. Temporary bonding jumpers are used in the handling of flammable liquids and gases, so that static charge on a vehicle or portable tank does not ignite ...
One side is connected to a flexible supply hose; the other may be attached to a manifold, valve, tool, or another hose. A female coupler is used on the supply side, and a male nipple is used on the receiving side. Fitting profiles have identifiable geometry on the male end, but care must be taken to use a compatible coupler.
Compression connectors on an isolating valve; the reddish part is a copper compression ring Compression fittings (sometimes called "lock-bush fittings") consist of a tapered, concave conical seat; a hollow, barrel-shaped compression ring (sometimes called a ferrule); and a compression nut which is threaded onto the body of the fitting and ...
Box connectors join conduit to a junction box or other electrical box. A typical box connector is inserted into a knockout in a junction box, with the threaded end then being secured with a ring (called a lock nut ) from within the box, as a bolt would be secured by a nut.
Grounding connectors. Connectors for earthing installation are a means of communication between the various components of the earthing and lightning protection installations (earthing rods, earthing conductors, current leads, busbars, etc.). For high voltage installations, exothermic welding is used for underground connections.
A compression fitting 15 mm isolating valve. A compression fitting is a fitting used in plumbing and electrical conduit systems to join two tubes or thin-walled pipes together. . In instances where two pipes made of dissimilar materials are to be joined (most commonly PVC and copper), the fittings will be made of one or more compatible materials appropriate for the connect
The "Air King" [14] universal air hose coupling, also known as a "Chicago style" fitting, is malleable iron or brass "quarter turn" "sexless coupling" usually found on large pneumatic tools like jackhammers. [6] The fitting is considered "universal", because a common two-lug head is used on all sizes ranging from 0.25 to 1 inch (6 to 25 mm).
