Black serie acetal resin fitting PM serie

John Guest’s fittings from the PM series are made from acetal black resin and equipped with nitrile (NNBR) o-rings for food use. They are particularly fit for beverages like beer or soda.
However they are also fit for gasses like N2 and CO2 (made following the specifics of the Brewers and Licenze Association), and also fit for mixed gasses, pneumatic applications, and vacuums.
