Houston, TX - VICI Valco’s Cheminert high pressure PEEK fittings are rated at 5000 psi with fingertight nuts, well beyond the burst strength of most PEEK tubing. The taper angle and detail design conform to the industry standard established by the Valco line. The Cheminert UHPLC Fitting designs permit direct connection of 360 micron OD fused silica, PEEK, stainless, or electroformed nickel tubing without having to use troublesome liners. Because of the fitting’s compact size and fine 2-56 threads, a leak-free connection that seals at pressures well in excess of 20,000 psi can be easily formed with the available manual tool. 360 micron fittings in PEEK can be used safely up to 10,000 psi. The 360 µm fittings are available with a PEEK or stainless nut; the PEEK nut is supplied with a glass-filled PEEK ferrule, while the stainless nut uses a 316 SS ferrule. The ferrule snaps into the nut so that the fitting is “one-piece”, but the ferrule is free to rotate and does not twist the tube as the nut is tightened. A range of micron bore sizes are available.
