2. Piping and plumbing fitting - Wikipedia

   en.wikipedia.org/wiki/Piping_and_plumbing_fitting

   Push-to-pull fittings are easily removed compression fitting that allows pipes to be connected with minimal tools. These fittings are similar to regular compression fittings but use an O-ring for sealing and a grip ring to hold the pipe. The main advantage is that it can easily be removed and re-used, it is easy to assemble, and the joints are ...

3. Cross-linked polyethylene - Wikipedia

   en.wikipedia.org/wiki/Cross-linked_polyethylene

   A cross-linked polyethylene (PEX) pipe. Cross-linked polyethylene, commonly abbreviated PEX, XPE or XLPE, is a form of polyethylene with cross-links.It is used predominantly in building services pipework systems, hydronic radiant heating and cooling systems, domestic water piping, insulation for high tension (high voltage) electrical cables, and baby play mats.

4. Quick connect fitting - Wikipedia

   en.wikipedia.org/wiki/Quick_connect_fitting

   Quick connect fittings are intended to be applied more easily than traditional fittings, requiring only that the pipes be pushed together firmly to lock the teeth of the fitting firmly. The teeth are forced deeper into the tubing when opposing force is applied to them, preventing their separation from the tubing.

5. Viega - Wikipedia

   en.wikipedia.org/wiki/Viega

   In 1995 Viega presented press technology that joined copper and PEX tubing to plumbing fittings. Products like Viega's ProPress and MANABLOC define a trend to mitigate installation errors. Green or innovative buildings use Viega or other related products for radiant heating and snow melt applications.

6. Push-to-pull compression fittings - Wikipedia

   en.wikipedia.org/wiki/Push-to-pull_compression...

   Push-to-pull, push-to-connect, push-in, push-fit, or instant fittings are a type of easily removed compression fitting or quick connect fitting that allows an air (or water) line to be attached, nominally without the use of tools (a tool is still usually required for cutting tubing to length and removal).

7. Tripping (pipe) - Wikipedia

   en.wikipedia.org/wiki/Tripping_(pipe)

   This is done by physically breaking out or disconnecting (when pulling out of the hole) every other 2 or 3 joints of drill pipe at a time (called a stand) and racking them vertically in the derrick. When feasible the driller will start each successive trip on a different "break" so that after several trips fresh pipe dope will have been applied ...

8. Air-line fitting - Wikipedia

   en.wikipedia.org/wiki/Air-line_fitting

   Nipples with mating safety couplings. Also known as pneumatic couplings, quick disconnects, air couplers, quick connect couplers, and quick couplers, hand-operable air-line fittings allow manual disconnection of gas supply lines, including compressed air and breathable air (a subset of breathing gases).

9. Plastic pipework - Wikipedia

   en.wikipedia.org/wiki/Plastic_pipework

   Plastic Pipe lengths manufactured in Australia by extruding HDPE material.. Plastic pipe is a tubular section, or hollow cylinder, made of plastic.It is usually, but not necessarily, of circular cross-section, used mainly to convey substances which can flow—liquids and gases (fluids), slurries, powders and masses of small solids.
