BioTight™ fittings
New biocompatible fitting system for small spaces
The newly introduced IDEX BioTight™ fitting system provides consistent biocompatible performance in low-pressure 1/4-28 flat-bottom port assemblies up to 200 psi (14 bar). These fittings are ideal for small spaces and require very little torque thanks to the metal-free press-fit ferrules that are available for 1/16” & 1/8” tubing OD. One universal PEEK nut accommodates all tubing diameters.
Instructions
- Slide the fitting onto your tubing and add the black-coloured lock ring, ensuring the ridge feature faces the fitting for 1/8-inch tubing.
- Slide the ferrule tube onto your tubing.
- Place the components into your intended port, inserting the port thread into the fitting while keeping pressure on the tube.
- Tighten the nut. Continue until you feel the lock ring bottom-out in the port. It’s that simple.
