All high pressure polymeric fittings are manufactured from high quality inert polymers to exacting tolerances. Most are rated for use up to 350 bar (5000 psi) with fingertight nuts, which is well beyond the burst strength of most PEEK tubing. Fittings made with special PEEK-HT can be used up to 1000 bar (14,500 psi).
Fingertight adapters
Color-It fingertight adapters fit all our PEEK and stainless hex-head nuts for 1/16" tubing.
Color-Sleeve adapters are designed to be used with our black PPS nuts and one-piece fittings.
