The 48 Series coupling system is available in POM, PVDF and a completely thermoplastic version with springs made of PEEK™ called RectuChem+. RectuChem+ products are refered to as CHEM+ in the tables.
The coupler is fitted with a double shut-off valve, enabling it to be connected to a single shut-off (non-valved) plug as well as a double shut-off (plug with valve).
