Fitting tools
Assistance for secure connections
Biotech Fluidics provide several tools that are designed to assist you when making connections with IDEX fittings. We offer torque tools that eliminate overtightening, extender tools that help you tighten fittings in hard-to-reach places, plus special wrenches and fitting removal tools. Choose a tool that match the head design of your fitting and fits the connection situation and the goal of your actions.
Note that tubing cutting tools are listed on a separate webpage.


Torque tools
Although originally designed for the VHP fittings, the torque tools can be used with any fitting that has a corresponding head style. There are two styles of torque tightening tools available for various applications.
The Torque Tools (VHP-1000 and VHP-2000) are breakaway torque wrenches designed to deliver a precise amount of torque to the fitting system. These torque wrenches come calibrated according to ISO 6789:2003 (± 6% of setting) and have been tested extensively with the reusable VHP fittings. Choose the appropriate torque delivered and the proper head style to work with the VHP fittings, increasing the ease of use with these fittings.
The VHP-4000 Torque Driver couples with the specially designed Extender Tools listed below and provides an externally adjustable torque setting. This tool along with the appropriate Extender Tools will tighten any IDEX Health & Science knurled polymer fitting in your system.

Extender tools
Extender Tools can be used to tighten most of our knurled nuts in hard-to-reach places. The extender tools listed with 1/4” Hex Drives are designed to adapt to any torque wrench with a female 1/4” socket, such as the VHP-4000 Torque Driver or a 1/4” wrench (A-304). Manual extenders are designed to be used without any additional tools.

Special wrenches and removal tools
Use the LT-300 Removal Tool to detach LiteTouch® and Super Flangeless™ Ferrules from tubing. Simply slide the appropriate tool blade slot between the lock ring and the ferrule body. With a slight twist, the ring will pop off, releasing the ferrule from the tubing. Please note that this Removal Tool will not work with the LT-135 Ferrule System.
The IDEX Wrench is slotted to fit over 1/16” & 1/8” OD tubing, and has 1/4” & 5/16” internal hex ends, to engage with the heads of the hex-head fittings most commonly used with IDEX valves and the VHP stainless steel fittings.
For your convenience, we also offer wrenches in three standard sizes. You will need two A-304 wrenches to tighten most nuts into unions (for union 1593, you need one A-304 and one A-320 wrench).
The FlushNut Wrenches (F-345 & F-346) are designed to tighten FlushNut fittings into 10-32 or 1/4-28 ports.
