RheFlex® Two-Piece Fingertight PEEK fittings provide inert, biocompatible connections for instrumentation

Pressure rated up to 20,000 psi (1,380 bar) when wrench tightened, stainless steel fittings are available in a variety of thread configurations for 1/16” and 1/8" OD tubing and are constructed from 316 stainless steel. The LiteTouch® Fittings System grips tubing at two compressions points to ensure holding to high pressures with Fingertight convenience, while also preventing polymer tubing from twisting. LiteTouch Fittings are available for use with 1/32, 1/16, or 1/8 in OD tubing sizes, and for 10-32 or 1/4-28 coned ports.

All polymer, One-Piece Fingertight Fittings are available for 1/32", 1/16", and 1/8” OD tubing sizes and are available in a variety of colors, materials, and lengths for virtually every application. This original design provides convenience and ease of use because ferrules will not stick in receiving ports making the fitting easy to find if dropped.

Two-Piece Fingertight Fittings are designed to connect 1/16”, 1/32”, 360 µm or 190 µm OD tubing to 10-32 coned ports. The two-piece design, along with a separate ferrule, allows the replacement of just the ferrule instead of the entire unit making these Fingertight fittings more economical than the one-piece version. Use a standard knurled head fitting for traditional fingertight applications or a fitting with wings built into the head for extra tightening leverage. A stainless steel hex headed fitting can be used for applications where a wrench may be needed for added tightening torque.

FlushNut™ Fittings are designed for tight-space applications where nut heads often interfere with each other. When coupled with and appropriate ferrule and tightened into a receiving port, the FlushNuts slotted head seats at or near flush with the top of the port allowing the fitting to reside in closer proximity than any other option on the market. All FlushNut Fittings are manufactured from 316-stainless steel, except the P-321 Plug, which is made of PEEK™ polymer. (To tighten these fittings appropriately, use either the F-345 FlushNut wrench for 10-32 threaded fittings or the F-346 FlushNut wrench for 1/4-28 threaded fittings.)

Each 1/16” fittings set contains a 10-32 threaded nut and a specially designed PEEK ferrule, and the 1/8” fittings sets a 5/16-24 PEEK nut and ferrule. Three lengths of the 1/16” nut are available; standard, short, and extra long. ReFlex Fingertight fittings are rated for use up to 7,000 psi (483 bar). Use ChromTRAC knobs (part number 6000-283) with RheFlex fittings for fingertight convenience and to color-code connections.
