10-32 Fingertight Fittings • Variety of Fingertights: short, regular & long; one-piece & two-piece; various materials • Pressures up to 7,000 psi (483 bar) • Temperatures up to 125 °C • Fingertights for 1/16" OD and smaller tubing • Replaceable Ferrules for two-piece versions Upchurch Scientific® introduced the world’s first Fingertight fitting in 1984. Fingertight fittings offer the convenience of making a tubing connection without the need for wrenches or specialized tools when tightening the fitting into place. Simply use your fingers to tighten the fitting into the receiving port! In 2005, we added the Rheodyne® RheFlex® Fittings, designed for use with many of the Rheodyne manual valves. RheFlex PEEK Fittings include ChromTRAC™ knobs in the color of your choice for visual identification and finger tightening of fluid connections without undesirable twisting of polymer tubing. Replacement 1/16” RheFlex PEEK ferrules and ChromTRAC knobs are available. Specify the ChromTRAC two-letter suffix for the color choice when ordering* (see the ChromTRAC Suffix Codes table below). For example, to order red ChromTRAC knobs with the RheFlex One-Piece Fitting, specify 6000-282RD.
*NOTE: If you do not add a color suffix to the desired part number, you will receive black knobs, except for part #6000-255 which comes without a knob unless a color is specified. Additionally, replacement ChromTRAC knobs are available in packages of 20 in the following colors and quantities: (2) Black (2) White (2) Green (2) Grey (4) Yellow (4) Red (4) Blue Click for more information. Upchurch Scientific and Rheodyne Fingertight fittings were designed to be used in conjunction with 1/16" OD tubing manufactured either from a semi-rigid or rigid polymer or from stainless steel. As an added benefit, Upchurch Scientific also manufactures some customized ferrules designed for use with our two-piece fittings but engineered to directly connect smaller tubing into traditional 10-32 coned receiving ports. The F-148 ferrule is engineered to couple 190 µm OD tubing into standard 10-32 coned ports, whereas the F-151 is engineered to couple 360 µm OD tubing into standard 10-32 coned ports. For electrospray applications, try our M-215 Conductive Perfluoroelastomer Ferrule instead of graphite ferrules. Because of its elastomeric properties, you can reuse this ferrule through many tightening/retightening cycles — unlike most graphite ferrules. Like graphite ferrules, voltage can be applied through the metallic fitting's port block, allowing the voltage to translate to the flow path through the ferrule. You may also use this ferrule with a stainless steel nut in a plastic port by applying the voltage to the nut. To order the desired nut to complement one of these specialized ferrules, determine which style nut you would prefer to use and then choose the part number that ends with a “-01”. (This version of the nut does not come with a ferrule, allowing you to save money and more efficiently customize your connection.) For example, if you want to use the F-148 ferrule with the nut for the F-200 fitting assembly, order F-200-01 along with the F-148 ferrule. Please Note: These specialized ferrules feature a fixed-length “nose.” While they will work in many receiving ports, in some applications these ferrules may cause leaks or a small pocket of dead volume, depending on the geometry of the receiving port. (See “Fittings Interchangeability” for more information). For best performance, Upchurch Scientific recommends using our “NanoTight fitting system” which will both facilitate the connection of a variety of capillary tubing sizes as well as adjust easily to the variety of receiving port tubing stop depths currently in use. Additional Note: We also offer a complete line of High Performance Fingertight fittings for use with higher temperatures and pressures. For more information, click here.
