FlushNut™ Fittings are designed for tight-space applications where nut heads often interfere with each other

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.

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.

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.

When coupled with an 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.)
