Colder Products Company’s new NS4 Series couplings are now available in an ABS version. They feature non-spill valves in a compact size and can be used when even a few spilled drops pose problems regarding safety, media costs or environmental regulations. The NS4/ABS couplings are lightweight, and Gamma stable. Both the new ABS version and the glass-filled polypropylene version of the NS4 couplings resist a wide variety of media.
