- More Info
An economically priced alternative to PEEK, this series of PPS ¼-28 nuts offers three low-pressure sealing options: inverted ferrule, flanged with washer, or VICI Jour’s patented collapsible ferrule.
These nuts provide excellent chemical and pressure resistance for 1/16” or ⅛” tubing (and 1/32” with inverted ferrule). They are fingertight when used with our Color-Sleeve adapters.
Color-Sleeve adapters turn PPS nuts into fingertight fittings and color-code different solvent lines for easy identification.
A PPS nut may also be used with a PEEK ferrule and stainless-steel bushing for high-pressure applications.
