For hoses and piping, a quick connect fitting, also called a push fitting, is a coupling used to provide a fast, make-or-break connection of gas or liquid transfer lines. Operated by hand, quick connect fittings replace threaded or flanged connections, which require wrenches. When equipped with self-sealing valves, quick connect fittings will ...
When the content of the SprüBü37 comes in contact with water, only the mustard gas in the outer layers of the lumps of viscous mustard hydrolyzes, leaving behind amber-colored residues that still contain most of the active mustard gas. On mechanically breaking these lumps (e.g., with the drag board of a fishing net or by the human hand) the ...
The idealized combustion of mustard gas in oxygen produces hydrochloric acid and sulfuric acid, in addition to carbon dioxide and water: (ClC 2 H 4) 2 S + 7 O 2 → 4 CO 2 + 2 H 2 O + 2 HCl + H 2 SO 4. Bis(2-chloroethyl)sulfide reacts with sodium hydroxide, giving divinyl sulfide: (ClC 2 H 4) 2 S + 2 NaOH → (CH 2 =CH) 2 S + 2 H 2 O + 2 NaCl ...
It uses unique, gas-specific threaded connections to fit equipment to station outlets. It is also used for the connection of additional features to equipment, such as in fixing a suction canister to a suction (Medical vacuum) regulator. Although DISS takes more time to affix, this has become the most popular choice as a threaded connection ...
The pin index safety system uses a face seal between the cylinder valve and the associated yoke clamp. There are two holes in specific positions on the cylinder valve body below the outlet port , in positions associated with the gas mixture, which prevent connection of the cylinder to a yoke or pressure regulator with a mis-matched set of pins.
POL is the common name for the standard CGA 510 (US Compressed Gas Association connection number). The Thread specification is .885" – 14 NGO – LH – INT, meaning 0.885 in (22.5 mm) diameter thread, 14 threads per inch (1.814 mm pitch), National Gas Outlet form, left-hand internal thread. [3]
Flared connections offer a high degree of long-term reliability and for this reason are often used in mission-critical and inaccessible locations. The tool used to flare tubing consists of a die that grips the tube, and either a mandrel or rolling cone is forced into the end of the tube to form the flare by cold working.
