Part Number #JR-55050-10

$19.00 Sale Save

An economically priced alternative to PEEK, this series of PPS ¼-28 nuts

  • High pressure rating – up to 480 bar (7000 psi) with 1/16" tubing
  • For 1/4-28 connections Available for 1/32" and 1/16" tubing
  • This combination of PPS nut, PEEK ferrule, and stainless steel bushing allows a high pressure connection in a 1/4-28 flatbottomed fitting detail.
  • Sold in packages of 10. Order nuts and bushing/ferrules separately.

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.

TECH TIPS

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.
