MicroTight™ One-Piece Fittings are designed for 360 µm and 1/32” OD tubing or MicroTight tubing sleeves and provide a superior fingertight connection with capillary tubing

MicroTight fittings withstand temperature to 125 °C, and can be used with NanoPort™ and MicroTight unions, adapters, and inline MicroFilters. MicroTight female nuts may be used with any MicroFerrule, but MicroFerrules are port specific and not interchangeable. 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. 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 1/16”, 1/32”, 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.

Upchurch Scientific® Ultra High Performance fittings are manufactured from a proprietary PEEK™ polymer blend (PK) which allows them to be used at higher temperatures (up to 200 ºC) and higher pressures. The VHP PK One-Piece fittings are available for 10-32 coned, 6-32 coned or M4x0.7 coned ports, and Two-Piece fittings are available to connect either 1/16" or 1/32" OD tubing into 10-32 coned ports in multiple styles. The VHP MicroFerrules are available for use with 1/32" or 360 µm OD tubing and are designed to connect to port-specific products that are engineered for those sizes of tubing.

The Very High Pressure (VHP) line of fittings are designed to withstand extreme pressures found in today’s high performance analytical systems. Pressure rated up to 25,000 psi (1,720 bar), this patent pending design is capable of up to ten repeat assembly cycles with no impact on pressure holding ability or carry-over. Available in 10-32 threads for 1/16” OD tubing or M4x0.7 threads for 1/32” OD tubing and constructed from a stainless steel and proprietary PEEK™ polymer blend (PK).

The all-Stainless Steel Very High Pressure (VHP) line of fittings are designed to withstand extreme pressures found in today’s high performance analytical systems. Pressure rated up to 30,000 psi (2,070 bar), these products are available in 10-32 threads for 1/16” OD tubing or M4x0.7 threads for 1/32” OD tubing and are constructed from 316 stainless steel. MiniTight™ One-Piece Fingertight Fittings are designed to facilitate the connection of capillary tubing to 10-32 coned ports designed for 1/16" OD tubing. The M-100 connects 0.020" OD tubing to traditional 10-32 coned ports. The M-110 is a special version of the MiniTight fitting that works with the MicroTight tubing sleeves to connect capillary tubes of an array of diameters to a standard 10-32 coned port. All parts are machined from PCTFE, and they have an upper pressure threshold of 4,000 psi (276 bar).
