Application Examples for the Use of Quick-Release Couplings with Liquids

Application:
- For internal water cooling on PCs. – To keep the PC mobile,
  low-leak quick-release couplings were used to connect/disconnect the expansion
  tank and the cooling device for the water.

- simple and quick connection of the cooling lines
- no air inclusion during coupling
- upon uncoupling, a barely noticeable film of the conveyed medium remains
  on the valve body
- made of nickel-plated brass – also available as a stainless steel version
- resistant to water additives
- one-hand operation
